Sep 08, 2010 · Abstract: The paper presents a new double layer three phase 4 to 6 pole-changing winding, with 48 slots and 6 terminals. In order to obtain a higher fundamental winding factor when winding is 6-pole connected, a degree of asymmetry is accepted for the winding when 4-pole … (PDF) A new 4/6 pole-changing double layer winding for PDF | The paper presents a new double layer three phase 4 to 6 pole-changing winding, with 48 slots and 6 terminals. In order to obtain a higher fundamental winding factor when winding is 6-pole COIL PITCH IN AN AC ARMATURE WINDING FULL PITCH … COIL PITCH IN AN AC ARMATURE WINDING CALCULATING PITCH FACTOR TERMS 1. Coil Throw: The location in an armature core of the sides of a coil starting in slot number one (1). Example: the throw could be slots per pole would be 48 ÷ 4, or 12 slots per pole. ... A 72-slot stator has a 4-pole, three-phase winding

Table I shows the winding factor according to the pole/slot combinations [4]. As can be seen in Table I, if the pole/slot ratio is 10/12, 14/12, 16/12, 20/24,…, the maximum winding factor of 0.966 can be obtained.
The best in the world, 12 / 6 pole winding in 48 slots. Offer for manufacturers and designers of electric motors, as well as technicians dealing with motor repair. If you are dealing with motor design, you probably know the reason why this slot-pole combination is so tricky. We have managed to create a winding with the lowest content of harmful
