On the sensorless synchronous direct drive control of permanent magnet motor for three-blade roots vacuum pump

Different from the traditional permanent magnet motor, the permanent magnet motor for three blade roots vacuum pump (PMM for TBRVP) is difficult to use sensors (or encoders) to achieve multi-motor collaborative control due to its special structure, extreme operating environment and harsh operating r...
