Discussion Starter · #1 · Aug 23, 2012 (Edited) Hi, we are ready to do a test rewind for an industrial AC induction motor. We have a motor, an aluminum frame 7.5 kW nominal 4-pole 50 Hz motor that weighed 50 kg. We already did strip old windings from the stator, and built a simple winding machine, and will be getting a 22 kg reel of new.. Calculation: Number of poles = 6. Total number of coil = 36. Number of slots = 36. P o l e p i t c h = ( N u m b e r o f c o n d u c t o r s) N u m b e r s o f p o l e s. Pole pitch = 36 / 6 = 6. In the case of Full Pitch winding, the full pitch is equal to pole pitch is 6. Download Solution PDF. India's #1 Learning Platform.

To the number of winding slots per generator pole. In Figure 2 (top half), which shows a 4 pole machine with 48 total slots, there will be 12 slots per pole, and since the coils span 10 slots, the alternator slot-to-coil ratio is 10/12, or "5/6 pitch." In the lower half of the illustration we see an alternator winding that spans 8 slots, so..

The number of brushes required by this winding. equal to the number of poles. is always equal to 2. 5. The machine using lap winding requires equalizer rings 5. The machine using wave winding does require dummy. for obtaining better commutation. coils to provide the mechanical balance for the armature. 6. The original surface mounted PM synchronous motor has 6 poles on the rotor iron and 36 slots in the stator iron. One pole of the motor is shown in figure 1. The winding is double layer and excited with 3 phase supply. Slots per pole per phase (spp) are 2 (36/3*6). The magnets are radially magnetized. Their operating point is Br =1.08 Tesla and. 6 A/mm2. In the light of these parameters, the slot/pole combinations of 24/18, 24/20, 36/24 and 36/30 which are suitable for in-wheel BLDC motor structure are investigated by means of FEA study. FEA is rather useful particularly for divergent slot/pole combinations [3, 15-17]. For the electromagnetic analysis ANSYS Maxwell software.
