If the resistance value unbalance is within 5%, there is no problem. If the deviation is large, it indicates that there is something wrong with the winding, and there may be problems such as inter tur

Generally, the three-phase motor will not be short of phase, and the phase missing is the three-phase power supply. If you must know how to use a universal meter to measure whether the three-phase mot

① For the outer sliding bearing, the motor must measure the air clearance.

② Use a feeler gauge or special measuring tool to measure the air gap values of the stator and rotor at the upper, lower, le

The basic rotation principle of three-phase asynchronous motor. The three-phase asynchronous motor works by rotating magnetic field, and its working principle can be intuitively understood through the
