交流电机的缺点：

1. 控制难度较大：相对于直流电机，控制交流电机的转速和效果需要复杂的电子电路，使得其在控制方面相对复杂。

2. 启动困难：由于交流电机的运转相关于“旋转磁场”，因此如果起动速度较快或者负载较重，其需要很大的起动电流，这对小功率的设备来说可能会做成较大的压力。

3. 负载效率偏低：由于它是电磁式设备，负载效率有时会因磁转换效果的不同而产生一些浪费。

4. 可靠性延迟：交流电机在启动时与运行时相关的电流频率和电磁场峰值，有时需要时间的适应过程，其运行效率可能在两三分钟后才能稳定。

5. 需要稳定的电源：当电流和电压波动比较大时，交流电机有时可能会表现出不同的失真情况，尤其是在频率变化时。
