The common external faults of the motor are mainly manifested in the following aspects, and the method of discharging the fault. Senli Motor Xiaobian simply lists some. Below, we will understand the common faults of the three-phase asynchronous motor.
I.
Fault problem: the motor can not turn after power, but no noise, no odor and smoke.
Solution: Check whether there are breakpoints in the power circuit switch, fuse, and junction box. If so, repair them.
Two.
Fault problem:Three-phase asynchronous motorNo load current imbalance, the three-phase difference may be rewound, the stator three-phase winding turns are not equal, winding head and end of the wrong connection, power supply voltage imbalance, winding there is a short circuit between turns, coil reverse connection and other faults.
Solution: Eliminate and eliminate these faults one by one through the winding turn impact voltage tester and bridge test.
Three.
Fault problem: the asynchronous motor does not turn after energizing, and then the fuse is burned, which indicates that there may be a lack of a phase power supply or a short circuit between sub-windings, the stator winding is grounded, the stator winding wiring is wrong, etc.
Solution: First check whether there is a phase of the brake is not good, the power circuit is the voltage machine, the turn test instrument, the bridge one by one to eliminate the fault point.
