There are several types of electrician employment certificates for Dongguan 2016 Shijie Electrician Training

If the motor rotor is heavy and the shaft extension is long, a crane can be used to extract the rotor. During operation, use the crane's wire rope to hang the rotating shaft, slowly move the center of gravity of the rotor to the outside of the stator, and then place its removed end on a bracket padded with insulating cardboard. Then tie the crane's wire rope to the rotor's center of gravity to lift the rotor. out. When the rotor shaft of the motor is short and the center of gravity of the rotor cannot be moved out of the stator, a steel pipe (dummy shaft) of appropriate length can be added to the shaft. When pulling out the rotor, be extra careful to prevent scratches on the stator winding. If necessary, put insulating cardboard on the end of the coil for protection

Check whether the core laminations are tight and have no defects such as burrs and corners; whether the clamping bolts are symmetrically pressed and whether the chains, pins, etc. are loose; whether there are any debris blocking the ventilation trench and whether the ventilation plates are welded firmly. Check whether the coil insulation has bubbles, peeling and damage; whether the binding wires, slot wedges and pads of the coil are complete and fastened, and whether they are loose, moving or the slot wedge protrudes from the iron core; check whether the magnetic poles and the coil are firmly fixed and insulated Whether the insulation of the bolts is good, whether the compensation coil on the palm is tightly wedged, and whether the connections are bent or short-circuited.
