Electric fan motor winding tap repairs

Speed motor winding tap repair experience we described below：

1. Removal of the old winding electric motor: These are basically single-phase four-pole rotor motor sixteen slots. Remove fixed, four screws and the lower end of the stator core, the stator core together with winding can be removed, but turn the leaf fan, Bishan, a small desk fan, the lower cap would buckle in the middle of the core, the core which is difficult to remove, first from the two end caps with a screwdriver to pry open the seam, remove a cap; core card in the other end cap in with a screwdriver to pry around the core, and slowly remove the core, absolutely not hammer to knock the cover cap to prevent deformation.

2. Replace fan stator winding: winding tap speed motor is basically a secondary winding secondary winding tap tap, simple, and start-up performance and operating performance are good secondary winding to the secondary winding grouping method is total number of turns in each slot of 1: 2 : 3 ratio separately, and then the three groups of coils is embedded in the same manner as the sub winding slots, these last three sets of coils can be connected in series.

For example secondary winding eight slots (stitches package should make a note), the total number of turns per slot 1200 turns; a first winding four line package, 200 turns per pack; second winding 400 turns of four packages per pack; four packages tertiary winding 600 turns per pack.

That is the first to third winding turns, respectively, the total number of turns (1200 turns) 1 / 6,2 / 6,3 / 6. Then these three sets of coils embedded in the same way the secondary winding of the eight slots to form a quadrupole wiring method is to end the first set of coils connected to a second set of coils of the first, leads first to second gear;. Last second set of coils are connected to the first third set of coils, leads first to third gear. The first group was the first deputy head coil windings; the tail end of the third set of coils of the secondary winding.

3, the installation:

(1) the ceiling fan winding core has been replaced, first uniformly placed in a cap, placed in a depth of 1/2 of a thickness of the core.

(2) loaded rotor wear another cap, if the rotor is not flexible, and can be used a rubber mallet or stick to gently tap the housing and the shaft.
