Induction Motors

Two original numerical techniques are developed for the finite element (FE) transient analysis of induction and permanent magnet motors operating in demanding aerospace applications. The first technique is the electromagnetic and thermal analysis weak coupling using a multiple slices 2D FE model. The advantage of the specific technique is the representation of complex actuator geometries including skewed magnets and winding ends, by using a low computational cost 2D model while taking into consideration temperature dependent material attributes. The second technique consists in the development of properly defined boundary conditions for the emulation of the cooling housing of actuators. Those boundary conditions are applied at the outer surface of the actuators in contact with the housing and eliminate the need of modeling complex 3D geometries of highly integrated actuator housings.

Currently, the feasibility to replace standard efficiency electric motors with higher efficiency ones is assessed with considerations differing from real operating conditions in the industry. This study compares the feasibility of replacing 26 standard efficiency motors (IE1) with high-efficiency efficiency ones (IE2 and IE3) in a sugar plant, based on three different energy scenarios and considering the incremental costs or depreciated costs of motors. Energy scenario 1 consider that motors operate for 6000 h/year at full load and nominal efficiency. While scenarios 2 and 3 consider the measured operating time and the load factor of motors. The results show that scenario 1 overestimates electricity consumption between 2 and 18 times, contrasted with a difference of 1e7% in scenarios 2 and 3, leading to saving potentials in scenario 1 between 1.2 and 33.4 times higher than for scenarios 2 and 3. Considering the incremental costs in scenario 1, it is feasibly to replace all the motor...

For transient stability analysis, the rotor dynamics of the induction motor have to be included. These dynamics affect the system stability when severe disturbances hit it and cause frequency deviations. For large systems, frequency deviations are small. However, it may cause loss of synchronism and break the system into smaller areas. Motor loads are sensitive to system frequency deviations. Any change in the grid frequency, changes extremely the slip. This follows by changes of the motor torque and the motor speed. The demanded active and reactive powers change as well. Natural frequencies of induction motors is considered a unique property has a great effect on its behavior during different operation conditions. This work presents the performance of the induction motors through different power systems. Based on time domain simulation models study the natural frequency of induction motors, their response in normal and abnormal operation is analyzed to illustrate the dynamics associated.

Selection of electric motors and designing of efficient motor drives are important issues in the manufacturing of electric vehicle's traction system, especially with the highly competitive electric vehicles' market. Many electric motors can be used to drive electric vehicles, but the induction motor (IM) and the interior permanent magnet synchronous motor (IPMSM) are the dominant ones. This paper introduces a dynamic comparative analysis of the IM and the IPMSM in electric vehicles applications. To conduct this analysis, two identical IM and IPMSM have been selected and two motor drives have been built using field oriented control (FOC) techniques in Simulink software. The motors were used to drive identical vehicle body models with a fuzzy logic controller used to control the vehicle's speed. Both motors were compared mainly in terms of the speed and the torque responses with and without vehicle body load. The results showed a convergent performance between both systems; however, the IM-driven vehicle model has a little faster response compared to the IPMSM-driven one, whereas the latter has a higher torque ripple compared to the IM drive.

Indirect Field Oriented Control (IFOC) is very popular technique in industries due to its simple designing and structure, in comparison to the direct method since it requires flux and torque estimators. This paper presents detail calculation of all values needed for the development of an indirect rotor flux oriented induction motor model fed by a current-controlled voltage source inverter. With the calculated values for 1 hp 50 Hz 3 phase induction motor; an indirect rotor flux oriented model is developed using MATLAB/Simulink. The simulation results are outlined and discussed.

We have designed this project to control the speed of a single phase induction motor by using cycloconvertor technique by thyristors. Induction motors in particular are very robust and therefore used in many domestic appliances such as washing machines, vacuum cleaners, water pumps, and used in industries as well. A.C. motors have the great advantages of being relatively inexpensive and very reliable. The induction motor is known as a constant-speed machine, the difficulty of varying its speed by a cost effective device is one of its main disadvantages. As the AC supply frequency cannot be changed, so this project uses a thyristor controlled cycloconverter which enables the control of speed in steps for an induction motor. A pair of slide switches is provided to select the desired speed range (F, F/2 and F/3) of operation of the induction motor. These switches are interfaced to the microcontroller. The status of the switches enables the microcontroller to deliver the pulses to trigger the thyristor in a dual bridge. Thus, the speed of the induction motor can be achieved in three steps i.e. (F, F/2 and F/3). This very concept can be further enhanced and implemented to control the speed of a three phase induction motor. It can also be coupled with firing angle control for any desired speed.

Three phase induction motors in various industries are very important to be stopped within a short time. Dynamic braking of three phase induction motor has been commonly used to break an induction motor electrically. However, dynamic braking method does not stop the rotation of the motor as quick as mechanical braking. In this research, will discuss about dynamic braking using direct current method. Buck Converter design is made as DC source for direct current braking in three phase induction motors. Based on the result of measurement, buck converter can operate on minimum duty cycle 10% with output voltage 11,3V and output current 0,16A. When duty cycle operates at maximum duty cycle 90%, output voltage is 29,95V and output current is 1,15A. The test results also prove that the buck converter was successfully applied to direct current braking of the three phase induction motor and has succeeded in stopping the motor fastest in 0.18 seconds when the motor are not coupled with DC generator and 1.7 seconds for the condition is coupled with the DC generator. Keywords— 3-ph induction motor, buck converter, direct current braking I. INTRODUCTION Three-phase induction motors are commonly used in various industries because of their simple construction, easy use, high durability, high reliability, and low maintenance costs. One of the important control parameter of induction motor is braking. Braking is needed when a system requires in stop process, either when the device operation is completed or when there is a system error to secure the equipment at work. One method of three phase induction motor braking is dynamic breaking method by injecting direct current on the stator coil of three phase induction motors after the stator coil is removed from the supply.

This paper presents the phenomenon of electromagnetic noise and vibrations in electrical machines , and focuses on the analysis of the noise reduction of skewing in surface permanent magnet synchronous machines (SPMSM). The origin of the main rotating and pulsating magnetic forces is detailed in terms of stator slotting and rotor magnet harmonics, and the optimal value of stator and rotor skew is derived. Some numerical electromagnetic and vibroacoustic simulations are then carried and confirm the analytical work. It is shown that the minimization of cog-ging torque does not necessarily lead to lower acoustic noise. Depending on the vibration waves responsible for noise (pulsating or rotating), the optimal rotor skew value is different. It is therefore necessary to run electromagnetic and vibroacoustic simulations to optimize the noise level of the electrical machine.

The modelling of 3 phase induction motor which is a dynamic load is carried out with the help of dq0 axis transformation. The dq0 axis transformation is used to create such model because it reduces the complexities of time-varying variables. Simulink Implementation of an induction machine using dq0 axis transformations of the stator and rotor variables in the arbitrary reference frame has been carried out. The relevant equations are derived and stated at the beginning, and then a generalized model of a three phase induction motor is developed using MATLAB. In the end, the parameter of the load model is estimated using system identification app of MATLAB.

The dynamic characteristics such as speed and torque as well as voltages and currents of PWM brushless DC motor inverter are analyzed with a MATLAB model. The contribution of external load torque and friction torque is monitored. The switching function technique is adopted for the current control of the embedded three-phase inverter that drives the brushless DC motor. In switching functions, power conversion circuits can be modeled according to their functions rather than circuit topologies. Therefore, it can simplify the overall power conversion functions. The trapezoidal type (back EMF) is used in the model as it has lower switching loss compared with sinusoidal type (back EMF). Results show reliable time analysis of speed, torque, phase and line voltages and currents. The effect of current commutation is clearly observed.

A mathematical model for a three-phase induction motor was developed using d-q axis theory. Investigations were carried out using MATLAB/SIMULINK for steady-state, as well as transient conditions when the motor is supplied from balanced and unbalanced voltage sources. Furthermore, soft and smooth starting of 3-phase induction motor was studied and analyzed through the proper choice of the firing angle () of thyristors over the starting period to control the applied voltage. The simulation results were analyzed for three induction motors with different power ratings: 3 hp, 50 hp and 500 hp. The results showed that the soft starting method has the lowest current magnitude, thus eliminating shaft-torque pulsations during the starting process and ensuring smooth build-up of torque and speed. It was also shown that increasing the firing angle caused torque and current magnitudes to increase faster, but at the same time it caused the motor to reach the steady-state faster.

The paper presents the description for diagnostic methods of induction motor's stator windings fault. The presented methods use Frequency Response Analysis (FRA) technique for detection of Winding Faults in Induction Motor. This method is previously reliable method for faults diagnosis and detection in many parts of transformers including transformer windings. In this paper, this method was used for motor windings faults detection. This paper presents the FRA response interpretation on internal short circuit (SC) fault at stator winding on three cases studies of different three-phase induction motors (TPIM), were analysed according to two status: healthy induction motor at normal winding status and same motor with windings shorted of main windings. A conclusion of this paper provides the interpretation of and validation the FRA response due to internal SC fault case by using NCEPRI algorithm, which is considered as one of certified statistical indicators. The proposed method in this paper had a useful result for detect and diagnosis of stator windings faults of TPIM. The applications of developed method can be used to detece the other machines types faults.

This paper presents a proposed sensorless algorithm for induction motor (IM) speed control based on artificial neural networks (ANNs). The Indirect rotor field oriented (IRFO) technique is applied to control the motor. It is designed based on the proportional integral (PI) controller. The particle swarm optimization (PSO) algorithm is used as a good solution for the problems associated with the design of the proportional integral (PI) controller gains. The PSO is compared with the conventional methods. The proposed controller (PSO-PI) is then integrated with the artificial neural network (ANN) speed estimator. The MATLAB/Simulink is used for the simulation of the system. The obtained simulation results for the proposed technique are very close to the actual ones.

An effective scheme of induction motor control without using stator sensor is proposed in this paper. The effective scheme consist of speed calculation algorithm and voltage/frequency control. The speed calculation algorithm is achieved by sensoring the current of stator and compared with the prospective speed then calculation by DSP. The principles of constant voltage/frequency (V/Hz) control for AC Induction motor and sine wave generation of PWM technique are used. The control system has been tested at the real time operating conditions and the experimental results have shown that the system has good characteristic in steady state and during transient as well.

Induction motors are widely used in transportation, mining, petrochemical, manufacturing and in almost every other field dealing with electrical power. These motors are simple, efficient, highly robust and rugged thus offering a very high degree of reliability. But like any other machine, they are vulnerable to faults, which if left unmonitored, might lead to catastrophic failure of the machine in the long run. On-line condition monitoring of the induction motors has been widely used in the detection of faults. This paper delves into the various faults and study of conventional and innovative techniques for induction motor faults with an identification of future research areas.

In this paper, a smart drive system of the induction motor (IM) is proposed and adapted for applications in electric vehicles (EVs). Objectively, the EV drive systems are robust over wide speed and torque ranges. The proposed drive system is independent of encoder (encoderless) and concerned with the torque control drive (TCD) and indirect rotor field-oriented control (IRFOC) using the sliding mode observer (SMO). This arrangement of monitoring system and control techniques are smartly integrated for the IM applications in EVs. The encoderless technique utilizes SMO to estimate the stator current, rotor flux angle, and rotor speed. The SMO is verified in motoring mode at very low and zero speed conditions. The accelerator pedal is utilized for TCD to generate the reference torque required to accelerate the EV by the driver. The rotor flux angle is estimated based on IRFOC method. The laboratory waveforms illustrate the robustness of the encoderless control of the IM-based torque con...

This paper presents the results of a study about the effects of unbalanced voltages on the energy performance of three-phase induction motors. The principal contribution of this paper is that presents a detailed analysis of the influence of positive and negative sequence voltage components and the angle between them on several characteristics such as: line currents, losses, efficiency and power factor under different voltage unbalanced conditions. A three-phase induction motor of 3 HP was used as a case study. The results of the investigation show that the positive sequence voltage must be considered together with the voltage unbalance factor (VUF) or percent voltage unbalance (PVU) index to evaluate the performance of the induction motor. It is also shown that the behavior of the motor load influences on the positive sequence parameters next to the voltage, while in the case of negative sequence only influences the negative sequence voltage.

Abstract:—Fault diagnostics of induction machines have been widely researched however, an integrated motor control with automated fault detection, prevention and condition monitoring is still missing. Condition monitoring can reduce the downtime of the processes and increase the maximum interval between failures, thus minimizing the number and cost of unscheduled maintenances, which is highly beneficial. Also an integrated approach can reduce the cost of the system and enhance its integrity. A new algorithm is introduced for control with embedded systems fault prediction and analysis of AC induction machines. The embedded control and diagnostics algorithm is implemented using the Analog Devices Blackfin ™ ADSP-BF531 digital signal processor (DSP) which mainly controls the AC induction machine, and communicates to a Windows XP ™ PC through the USB to monitor and display the electrical parameters of the inverter and the Motor. The algorithm employs various techniques to detect and pre...
