Sin-Cos Encoder Design
Permanent magnet synchronous motor gearless transmission frequency conversion speed regulation drive mode will become the main development direction of elevator drive technology. According to the test of the National Small and Medium-sized Motor Testing Center, the efficiency of the hydromagnetic conformal motor is 96.4%, and the power factor is 0.99. In order for the permanent magnet synchronous motor to achieve high-efficiency index parameters during operation, the electromagnetic field added by the frequency converter to the motor stator winding must be perpendicular to the permanent magnetic field of the motor rotor. Therefore, a high-precision rotary encoder is required to track the permanent magnet in real time. The initial position of the magnetic field. This is different from the traditional asynchronous motor.
