Permanent magnets

Currently, permanent magnet synchronous motors with on-line starting are being increasingly researched and applied to partialy replace squirrel cage asynchronous motors, which are commonly used. The reason is that these motors have many advantages such as high efficiency, and high power factor value, stable speed, higher power density compared to induction motors, and the ability to self-start.

Brushless Permanent Magnet Motor Design- P7: You've just picked up another book on motors. You've seen many others, but they all assume that you know more about motors than you do. Phrases such as armature reaction, slot leakage, fractional pitch, and skew factor are used with little or no introduction. You keep looking for a book that is written from a more basic, yet rigorous, perspective and you're hoping this is it.
