Abstract :
A trapezoidal waveform is usually used instead of the actual back EMF in numerous research literatures on simulation of brushless DC (BLDC) motors, which causes the errors to the simulation and calculation of the motor. This paper adopts the flux linkage changing rate matrixes of the permanent magnets to calculate the back EMF, establishes the mathematical model of a 30 kW six-phase BLDC motor based on it, simulates the dynamic performance of the motor, and verifies the validity by experimental results.
