Abstract: Generally, the FOC (Field Oriented Control) is used for PMSM (PermanentMagnet Synchronous Motors) control, and the rotary transformer is used as the rotor position tracking detector .In this paper, introduced the principle of the rotary transformer, and the methods to detect the initial position of the rotary transformer. Analyzed the methods to ensure the consistency of the initial position of the rotary transformer, the influence of the cogging torque to the initial position calibration and the way the initial position error effect the performance of the motor.
Key words: PMSM; cogging torque; rotary transformer; initial position calibration |
