When the equipment is running, it sometimes occurs when the three-phase asynchronous motor is powered on, but it does not rotate; So what are the causes of this? Today, Senli Electric Xiaobian will take you to understand the reasons why the three-phase asynchronous motor does not turn after being energized.
1Wiring error of control equipment;
2The power supply is not connected, such as the fuse is burned, the switch is faulty or the contact is poor, the lead is broken, etc.;
3The setting value of overcurrent relay adjustment is too small;
4The connection between the power supply and the motor is faulty;
5Motor windings have faults, such as interphase short circuit, grounding, wrong wire connection, open circuit, etc.
6The winding rotor asynchronous motor starts incorrectly or the starting resistance is too small;
7The motor bearing is faulty and stuck;
8The rotor core rub (sweep the bore), which is equal to increasing the excessive load;
9The motor load is too large or the mechanical rotation part is stuck.
