The permanent magnet synchronous motor

Proceedings of the Institution of Electrical Engineers, 1962
A synchronous motor, constructed by modifying an induction motor by fitting a permanent magnet inside the squirrel-cage rotor, is very useful for drives where synchronous operation is required or where the drop in speed of an induction motor is too great.

The Study of Permanent Magnet Demagnetization in Permanent Magnet Synchronous Motor

2021 IEEE International Conference on Advances in Electrical Engineering and Computer Applications (AEECA), 2021
Permanent magnet demagnetization is one of the common faults of permanent magnet synchronous motor, which seriously threatens the safe and reliable operation of the motor and reduces the service life of the motor. Based on the principle of permanent magnet demagnetization, this paper analyzes the causes of irreversible permanent magnet demagnetization.

Permanent magnet synchronous motor emulator

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
In order to test the performance of the motor driver, a power converter can be used to replace the real motor, both of which have the same electrical characteristics. This is a real-time control system. The foremost challenge in this system is the modeling of the real-time motor simulator based on the mathematical model of permanent magnet synchronous ...

Permanent-magnet motors for brushless operation

IEEE Transactions on Industry Applications, 1990
The design considerations for permanent-magnet motors intended for brushless operation are discussed. Two rotor configurations are described: the imbricated rotor and the segmented rotor. The segmented rotor is designed specially for high-speed operation.

Analysis of permanent magnet synchronous motors

IEEE Transactions on Industry Applications, 1991
A detailed representation of buried permanent magnet synchronous motors at steady state is presented. An equivalent circuit is proposed that accounts for the saliency of the machine and for the particular influence of iron core losses on the machine operations.
