效率特性：交流电机的效率特性是指电机在不同负载下的能量转换效率大小，通常采用效率-负载曲线来描述。当负载较小时，电机的效率较低；当负载增加时，电机的效率逐渐提高，直到达到大效率。

　　总体而言，交流电机的工作特性与其设计参数、工作条件和负载特性等因素有关，需要进行合理的设计和调整以满足不同的应用需求和工作要求。

　　交流电机转速公式为：

　　n = （120f） / p

　　其中，n表示电机的转速，单位为rpm（每分钟转数）；f表示电源的频率，单位为Hz；p表示电机的极数。

　　这个公式称为“同步转速公式”，它描述的是交流电机在理想情况下的转速，即在空载条件下电机的转速。在实际应用中，电机的实际转速受到负载和其他因素的影响，因此需要考虑转速-负载曲线和负载特性等因素来确定电机的实际转速。
