摘要： A system includes a permanent magnet motor having a rotor and a stator. The rotor and the stator have a configuration that causes the motor to generate a back-electromagnetic force (EMF) waveform that is substantially sinusoidal. The system also includes a motor controller having a sliding-mode observer configured to identify the back-EMF waveform and a position observer configured to estimate at least one characteristic of the motor using the identified back-EMF waveform. The stator may include multiple teeth projecting towards the rotor and multiple conductive windings, where each conductive winding is wound around a single tooth. The rotor may include multiple magnetic poles, where each magnetic pole has a span of about 60° or less. The sliding-mode observer may be configured to receive current measurements associated with three-phase signals and voltage commands generated by the motor controller. The position observer may include a proportional-integral (PI) regulator.
