Estun servo motor - how to choose a servo motor?
The selection of servo motor is not only affected by the weight of the mechanism, but also the movement conditions of the equipment will also change the selection of servo motor. The greater the inertia, the greater the acceleration and deceleration torque, and the shorter the acceleration and deceleration time, the greater the output torque of the servo motor. When choosing a servo motor specification, follow the steps below.

Estun servo motor - how to accurately control the torque of synchronous motor?
1. The electromagnetic torque of the synchronous motor is the interaction between the rotating magnetic field of the stator generated by the power supply voltage and the main magnetic field of the rotor;
2. The intersection angle of the magnetic pole axis of the rotating magnetic field of the stator and the main magnetic field of the rotor is called the work angle;
3. When the power angle is zero, the electromagnetic torque is zero, and the work is zero.
