Three-phase motor winding or a coil is embedded reversely, due to the direction of winding current flowing changes reversely, it will cause three-phase motor vibration, noise, and a serious imbalance in three-phase current, motor overheating, speed reducing, and the motor even can not start, and the fuse is blown. In general, one winding is reversed as external leads being connected correctly. Microampere meter block is available for inspection as this time, and the circuit is shown as the chart. When operation, the three-phase windings are connected at the head and tail according to the marks, then turn the three-phase motor rotor by hand, if the table pointer does not move, then the winding head and tail are connected correctly as shown in Figure (a).
