Cooling Fan Manufacturer conservation methods

"Cooling Fan Manufacturer" from the inside of the motor in terms of its internal protection devices, there is a thermal breaker that is part of the coil windings short-circuited, causing a sharp increase in heat, breaker circuit, the motor this case, the general strike . This rarely happens. Another is to start capacitance becomes smaller, although the nameplate reads those parameters, but a long time, the capacitance is reduced, resulting in smaller starting torque of the motor, can not drive the load. This simple, remove the "Cooling Fan Manufacturer" capacitance, go for a new, same model should be no problem. But the best for a 20 percent larger than the original, and will get better results. The motor shaft axial gap is too large will cause can not drag the load. If it is demolished motor, shaft axial gap is too large to be adjusted by adjusting shims. When installing the motor, the rotor must be concentric with the bearing for the job, slowly tightening the screws diagonally want, and then use a screwdriver to knock wood shaft, making concentric. Demolition "Cooling Fan Manufacturer" motor is simple, but putting it back on again is not casually pretend to go back, do not occur above case, otherwise, direct repair "bad".
