![]() ![]() If the cooling water (air), so that the coil can not heat, may burn coil.Ģ. Large-scale use of air-to-air heat exchanger, air-water heat exchanger cooling. General motor coil are air-cooled shell, submersible pump is water-cooled housing. During the operation of the motor should pay attention to the motor waterproof and moisture.Ĭ, pump mechanical failure caused by motor overload, the current is too large and burn coil.ĭ, the heat of the motor problems. Before the motor starts to check the coil insulation and phase-to-ground insulation, the use of different voltage insulation requirements are different, you can refer to the relevant national standards. ![]() In particular, the starting current of the motor is 3-5 times the rated current, so you should try to avoid starting the device with load or full load operation (mainly depends on the motor rated current and normal operating current matching margin)ī, the motor work in a more humid working environment. Overload operation of the equipment, so that the motor for a long time at rated current or over rated current operation. Over-current short circuit, there may be several reasons:Ī. If the fault is burning coil, mainly due to over-current caused, sometimes too high or too low voltage will cause the coil heat short-circuit, so first check the running voltage and rated voltage difference is not too much. First, first find out whether the motor burns the bearing (mechanical failure) or burns the coil (electrical fault). ![]()
