How to remove the motor

How to remove the motor?
(1) first remove the motor of the external wiring, and make a mark, for example, asynchronous motors, should be prepared with the three-phase power line to the label, for DC motors, shunt winding should make respectively, armature windings, and external wiring to the label. Then release the foot screws to separate the engine motor and transmission machinery.
(2) Figure 1-1 shows the tools to remove the motor shaft pulley or coupling, and sometimes need to add some kerosene in the pulley of the gap between the engine motor shaft, so that the penetration lubrication, easy to disassemble . Axis and round with some tight, but also the rapid heating of the wheel (and wrap the shaft with a damp cloth) to remove the wheel.
a) feet clamp b) three-pin clamp
(3) fitted with rolling bearings for the motor, should first remove the bearing cover, then loosen the end cap screws, and cover with the base case in the joints and marked (before and after the two end caps of the mark should not be the same), will remove the cover fastening screws screwed into the motor cover screw on a special set of two, will cover ejection. Without this engine screw motor, you can only use a chisel (also known as flat shovel) and hammer cover and base of the joints, remove the cover from the base station to. Cover, such as heavy lifting equipment applications Diaozhu cover, and gradually remove.
(4) removal of the engine motor with a brush, the brush should be removed from the brush holder on to the DC motor, but also to brush neutral position marked.
(5) out of the rotor must be careful not to bruise the stator coils, rotor weight is not, and can hand out; larger weight on the lifting equipment should be used to hang out, the steps shown in Figure 1-4 for the super-show. Both ends of the rotor shaft to the first set of hoisting ropes used with lifting equipment Diaozhu rotor (Figure 1-2a), slowly out, and should prevent the coil break something. Then put in a steel pipe shaft at one end, in order not to scratch the steel journal, can be lined with a thick cardboard tube (see Figure 1-2b) to continue to gradually remove the rotor, the rotor’s center of gravity has to be moved to the stator outside, in the rotor shaft Xiadian a bracket, the wire rope set in the middle of the engine rotor (see Figure 1-2c), all you can out of the rotor.
