工作原理：异步电机是通过旋转磁场和转子的感应电动势相互作用而产生转矩的，而永磁电机是利用永磁体和电流之间的相互作用来产生转矩的。

　　转矩特性：异步电机的转矩与转速之间存在的滑差，转矩随转速的增加而降低，且在低速时转矩较小；而永磁电机的转矩随着转速的增加而逐渐降低，但是其转矩与转速之间的关系比较线性。

　　运行控制：异步电机通常需要外部的电源提供旋转磁场，并且需要控制转子的滑差，才能保持稳定的运行；而永磁电机不需要外部电源提供磁场，因为永磁体本身就具有磁场，且转子的位置和转速可以直接控制。

　　成本和可靠性：由于异步电机的结构比较复杂，需要大量的铜线圈和绝缘材料，因此制造成本较高；而永磁电机的结构相对简单，制造成本较低，且由于没有复杂的控制器，因此可靠性更高。

　　综上所述，异步电机和永磁电机的工作原理、转矩特性、运行控制、成本和可靠性等方面都有所不同，需要根据具体的应用场景进行选择。
