The difference between synchronous motor and asynchronous motor

The difference between synchronous motor and asynchronous motor 1. The difference between motor synchronization: the synchronous motor speed is synchronous with the electromagnetic speed, while the asynchronous motor speed is lower than the electromagnetic speed. The synchronous motor, regardless of the load, as long as it does not lose step, the rotation speed will not change, and the rotation speed of the asynchronous motor will always change with the change of load size. 2. Structural difference: synchronous motor has high precision, but complicated manufacturing, high cost and relatively difficult maintenance. However, asynchronous motor is slow in response, but easy to install and use and cheap at the same time. Therefore, synchronous motors are not widely used as asynchronous motors. 3. Differences in use occasions: synchronous motors are mostly used in large generators, while asynchronous motors are almost used in motor occasions. 4. Main difference: synchronous motor and asynchronous motor have no slip (Difference between magnetic field speed and rotor speed).
