| Abstract |
Permanent magnet synchronous motors are often used in servo drives. The spatial distribution of the flux density can be rectangular or sinusoidal. The adjustment of the supply resulting in a pulsation-free torque is dependent on the flux density waveform. The motor with rectangular flux density is examined by Park-vectors in this paper. Basically there are two ways for the current control of the synchronous servo drive with rectangular flux density: the traditional two-phase conducting control with 60° skipping current vector, and the novel three-phase conducting control with continuously moving current vector. Both of them are PWM current vector control, and both of them can be implemented by hysteresis control or by pulse width modulator. The new method is derived, investigated and compared to the traditional one in more respects. |
