How to remove the brush holder, windshield and fan blades?
The method of disassembling the motor brush holder, hood and vane is as follows.
1 For a closed motor, after removing the pulley or coupling, unscrew the outer hood cap and remove the hood. Then unscrew the set screw on the fan end of the rotor shaft or remove the pin. Gently and evenly tap the fan around with the wooden hammer, the fan can be loosened and removed.
2 For the wound motor, first loosen the brush holder spring, lift the brush holder to remove the brush, and then remove the brush holder. To ensure an accurate reset during assembly, mark it before disassembly.
3 For small motors, the fan does not have to be removed, but is pulled out with the rotor. When the bearing in the end cap needs to be greased or replaced, the fan should be removed.
4 The method of dismounting the blades should vary depending on the installation method. Some of the blades are fixed with clamping screws, some are fixed with a head screw, and some are made of pins. The new type of plastic fan has two square holes for the purpose of disassembling the two hooks of the puller. The large shaft of the large motor is drilled with two threaded holes on the proximal shaft. It is used to alternately screw two screws commensurate with the hole to push the blades out. The blades of large motors are tightly packed and are not easily removed. Therefore, when disassembling the blades, the method of fixing the blades should be carefully observed, and then the corresponding disassembly measures should be taken.
