Analysis of Pulsating Torque for Permanent-Magnet Synchronous Motors at Synchronous Speed.

Direct Torque Control of Permanent Magnet Synchronous Motors

Fractional Slot Permanent Magnet Synchronous Motors for Low Speed Applications

Digital Control of Permanent Magnet Synchronous Motors

Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...

Pulsating Torque Reduction for Permanent Magnet AC Motors

Control methods for pulsation of torque reduction for the surface-mounted permanent magnet motors are discussed in the paper. The pulsation torque is a consequence of the non-sinusoidal flux distribution and due to interaction of the rotor’s permanent magnets with the changing stator reluctance. Proposed control method is estimator based. To assure parameter convergence Lyapunov’s direct method...
