Drive motor and its control system

AC permanent magnet motors mainly include two categories: Permanent Magnet Synchronous Motor (PMSM) and Brushless DC Motor (BDCM). The main difference between the two is that the permanent magnet excitation field is located in the stator phase winding. The electromotive force waveform induced in each phase of the PMSM is a sine wave, while the … Read More “What is an AC permanent magnet motor drive system?” »

Drive motor and its control system

The variable voltage and variable frequency speed regulation algorithm based on the steady-state model of the motor does not take into account the complex electromagnetic dynamic changes in the motor, so the dynamic control performance is not ideal. Until 1971, F.Blaschke of Siemens and others put forward the “control principle of induction motor field orientation”, … Read More “What is the vector control algorithm of AC induction motor?” »
