Full Parameter Estimation for Permanent Magnet Synchronous Motors
IEEE transactions on industrial electronics (1982. Print), 2021This article elaborates a novel online full parameter estimation method for permanent magnet synchronous motors (PMSMs). Usually, only two parameters can be estimated using voltage functions in the d-q frame due to the problem of rank deficiency. The α-β

The permanent magnet synchronous motor
Proceedings of the Institution of Electrical Engineers, 1962A 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), 2021Permanent 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, 2017In 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 ...
