tooth the same as Figure I-A. Figure I-C is an (8) pole, (18) slot motor with (3) phases and a (2) slot coil winding pitch. Figure I-D is a common brushless configuration for (3) phase motors with (4) poles, (12) slots and a (3) slot coil winding pitch. Figures I-E and I-F are brushless designs with (6) pole imbedded rotor magnets. Multi-pole (6 slots, 9 slots and 12 slots) stator coil ... This Multi-pole Stator Winding Machine is used for winding 6 slots, 9 slots and 12 slots stator. (3)Machine function and characteristic: Easy operation, high automation. PLC and touch screen control.. Reducing cogging torque in brushless motors | Machine Design The largest cogging torque waveform amplitude is the 12 slot in a family of curves for 6, 9, 12, and 15-slot lamination motors. The curves indicate that for an eight-pole motor with a 9-slot ...

Then I get current flowing into the page in slots 1 through 9 and slots 19 through 27. And I get current flowing out of the page in slots 10 through 18 and slots 28 through 36. That's 4 poles. Try it for any other valid three phase power. Here's a general rule of thumb when determining how many poles in a motor: End turns don't mean shit. fractional slot motor -2005-9 - RCGroups.com Fractional Slot PM Motors Professor Z. Q.

2 pole 4 pole 8 pole motors | Physics Forums Jun 26, 2011 · I assume you mean an induction motor. On a 60 hz system a 2 pole motor runs at 3600 RPM minus slip. 4 pole would be half of this speed, 8 pole a quarter, etc. Wiki should have something on this if you want more detail.
