Problems encountered by the wholesale ceiling fan electric machine include noise failure of ceiling fans, abnormal sound and noise of ceiling fans in normal operation, the main reasons are the loose structure of mechanical parts;Motor stator and rotor rubbing, as well as serious deformation of the blade.Balance correction should be carried out in time for ceiling fans with deformed blades.Under amateur conditions, a ruler can be used to measure whether the horizontal height of the tail ends of each blade is consistent. If any error occurs, the blade can be adjusted to the same height by pulling it.For severe deformation of the blade, professional personnel should be asked to correct or replace the blade.Some ceiling fans that have been used for a long time and not maintained in time make friction noise when their bearings are worn and run. At this time, a little oil can be added to the central shaft after cleaning to reduce the noise. If the bearings are badly worn and damaged, the bearings should be replaced.Ceiling fan governor failure Ceiling fan governor generally adopts reactance type governor, when the speed failure out of control, can be checked from three aspects.
1. The speed of each gear slows down, which is mostly caused by local short circuit between motor turns or windings;Or ceiling fan capacitor leakage, capacitance reduction and other reasons.
2. The speed of the first gear of the governor is normal, while the other gears are slow or fast. At this time, the fault occurs in the governor.You can remove the governor shell, check whether the switch contact solder joint is good, the transformer wire drawing head is not broken, short circuit and desoldering.
3. The governor and ceiling fan do not match to produce poor speed regulation, which should pay attention to the selection of matching governor in the installation of ceiling fan.
