Brushless motors cannot be driven with DC choppers, they do require 3 Phase or more AC currents. Also by using Inductor pick-up method, Sinusodial SVPWM with 1050Hz(depends on the variants) asynchronous pattern/ synchronous 24-pulse patterns can be observed. This can be imitated on VVVF simulations as well. undo Tags: Mobile edit Mobile web edit
