Abstract :
In this paper the skewed effects are introduced in an equation that describes the brushless (BDC) motor behaviour. Then, with this equation, the steady state, starting, and step change in torque performance are simulated and compared with those of an unskewed motor. The steady state torque-speed characteristics of the BDC motor are compared in different conditions, both with and without skewing. The dynamic and transient behaviour of the skewed BDC motor drive is simulated with sinusoidal, quadratic, and PWM waveforms. The results are in agreement with theoretical predictions.
