Problem-solving Method Of High-voltage Motor

Zhejiang Kening Motor Co.,Ltd | Updated: May 13, 2016

1. power supply does not work, fuse, overcurrent relays is too small, the wrong connection
2. the lack of a power supply, stator winding short-circuit, grounding, fuse section and small, short circuit power
Winding there are
3. circuit breakers, power supply voltage is too low, bearing
4. low voltage, welding cage rotor or breaking, motor overload, increased number of turns when you repair motor winding
5. stator three phase winding turns are not equal, tail-end of the winding connected to the wrong group turn to turn short circuit, coil reverse fault
6. squirrel cage rotor bars open or broken weld, winding rotor fault
7. power supply voltage is too high, large gaps or uneven
