Explosion-proof brushless motor in use is sometimes have some trouble, as in the face of all kinds of fault should be how to solve? Let's look at the specific method.
1, the explosion-proof motor can't start, and there is no any sound
:
(1)Blown fuse.
（2)The starter off the brake.
（3)The power supply without electricity.
2, explosion-proof motor can't start, have a buzzing sound
:
(1)Break, the power cord a photograph, or a fuse, fuse or a phase winding wire motor.
（2)The air gap between the stator and rotor not normal, the collision of the stator and rotor.
（3)Bearing damage.
（4)Jam is driven machinery.
3, brushless motor starting blown fuse
:
(1)The stator winding of an opposite.
（2)Short circuit or stator coil grounding.
（3)Bearing damage.
（4)Drive belt is too tight.
（5)Jam is driven machinery.
（6)Wrong operation when starting.
4, after the motor starting speed low
:
(1)The power supply voltage is too low.
（2)Will pick a star delta connection of the motor.
（3)Stator coil short circuit.
（4)The rotor end ring and cage faults or welding.
（5)Motor over load.
5, the motor temperature is too high, but no more than current rating
:
(1)The environment temperature is too high.
（2)Motor ventilation plugging.
（3)Motor oil sludge, dust too much heat.
6, an explosion in the operation of the explosion-proof motor in
