Application of Battery and Pointer Multimeters in Determining the Phase Sequence and Steering of Three-phase AC Induction Motor

三相交流异步电动机的旋转方向决定于其电源相序和定子三相绕组与电源相序的对应连接。根据负载要求的电机转向,用直流感应法确定三相交流异步电动机绕组的相序,从而确定三相绕组与三相电源正确的对应连接关系。对该方法的原理和实用性进行了介绍。

The rotating direction of three-phase AC induction motor is determined by its three-phase power supply phase sequence and the corresponding connection of the stator windings and power supply phase sequence.The winding phase sequence of the three-phase AC induction motor is determined by the DC induction method according to the motor’s rotating direction required by load,and as a result the correct corresponding connection of the three-phase windings and the three-phase power supply is determined.An introduction is made to the principle and practicality of this method.
