1. 工作原理不同：异步电动机的工作原理是在转子中产生感应电流，使其在旋转磁场中运动。而同步电动机的工作原理是在旋转磁场中，转子和旋转磁场同步旋转。

　　2. 转速控制不同：异步电动机是常规的交流电动机，转速只能由电源的频率决定；而同步电动机的转速可以通过改变电源频率来控制。

　　3. 启动方式不同：异步电动机在启动时，通过起动电阻或者变压器来限制启动电流，而同步电动机需要从外部提供起动，如在电机转子上附加起动电源。

　　4. 功率因数不同：通常情况下，异步电动机的功率因数是滞后于电压的，而同步电动机的功率因数是等于电压的。

　　5. 适用范围不同：异步电动机广泛应用于各个领域，而同步电动机适用于较高的功率和速度，如大型机械和电动车等。
