4 The University of Sheffield Electrical Machines & Drives Research Group 2p - pole number has to be multiples of two N s - slot number has to be multiples of 3 for a balanced 3-phase motor Possible combinations of slot and pole numbers 4-pole/6-slot, 8-pole/6-slot. May 07, 2018 In This Video I Showed Motor Rewinding 36 Slots 3 Phase 6 Pole With Diagram. Here I Described and Calculate All Data. If You New And Want To Learn Induction Motor Rewinding. This Video Is. We have demonstrated that 12-slot/10-pole SPM bearingless motor produces stable suspension force, whereas 9-slot/8-pole CPM and SPM bearingless motors and 12-slot/10-pole CPM bearingless motor have significant force ripple caused by the harmonics in the MMF distribution.

10 Pole Motor
Are there any generalizations that can be made about the # rotor bars and # stator slots in an induction motor?
One thing I know is that most higher-speed windings are integral-slot (vs fractional-slot) windings, the number of stator slots is divisible by 3 and by the number of poles.
Are there any other generalizations that can be made?
The reason is that vibration spectra sometimes show rotor bar pass frequency and stator slot pass frequency... but may not be able to distinguish if we haven't inspected the motor to count the number of bars and slots.
