Repair Methods: In this case we add a little oil to the motor on the line (if it can not find oil, rapeseed oil is used at home possible.
2 Most people probably will encounter the following phenomena, fans do not turn up, you move a hand to pull out or to wait a long time will slowly turn up, and then after a period of time will not find a hand to pull Moved. This phenomenon is most likely reason is that the start capacitor smaller fan inside, enough to make motor rotation.
Maintenance: Replace the capacitor fan inside, we can see that after removing capacitor fan motor housing. We can replace the same specification capacitors, capacitors may be a little larger than the original (not more than 20% of the original capacitance).
3 fan uses a long time, within the fan motor loss, after the motor bushings wear, it is easy to burn.
Maintenance: For non-rotating blades abrasion, the easiest is to replace the bushings
4 motor shaft axial clearance is too large can cause not drag the load.
Maintenance: If disassembled the motor shaft axial clearance is too large to be adjusted by adjusting shims. When installing the motor, the rotor and the bearing must be concentric job, slowly tightening the screws to the diagonal, and then use a screwdriver to knock wood shaft, making concentric. Dismantle the motor is simple, but putting it back on again is not casually pretend back, do not occur above case, otherwise, direct repair "bad".
