Abstract :
The brushless dc motor has a permanent-magnet rotor, and the stator windings are wound such that the back electro motive force(EMF) is trapezoidal. The paper develops a phase variable model of the BDCM and uses it to examine the performance of a BDCM speed servo drive system when fed by hysteresis and pulse width modulated (PWM) current controllers. Particular attention is paid to the motor torque pulsations. Some experimental verification is given.
