Harmonics in an Induction Motor Space harmonics fluxes are produced by the windings, slotting, magnetic saturation, inequalities in the air gap length.These harmonic fluxes induce voltages and circulate harmonic currents in the rotor windings. Craps or blackjack odds. If you assume that all of the motors are basically the same size, then. When the pole/slot ratio is a lower value 4/12= 1/3, the motor will have a higher KV for the same # of turns around each tooth than a motor with a 6/12 = 1/2 ratio, or a 6/9= 2/3.
4 pole motors will be same, but will include 72, 84(rarely), 90 (common on changeovers) or 96 (common on changeovers). 6 pole motors include all the above mentioned, but also include 54 slot designs. I've seen 108 slot motors as well. Anything above an 8 pole design will be above 72 slots. Colonial beach va facebook.

I'm in the process of trying to design a 36 pole induction motor for one of our test beds in the factory. It'll be used to test a range of winches that we manufacture and by controlling this motor through a VSD we can perform certain tests without the primary gear box that gets fitted to the completed unit.
I've looked on the web at the various motor manufacturers - a motor of this size (55kW)does not exist as far as I can see, hence my efforts to design a fit for purpose motor.
Despite my best efforts, all I can achieve is a 25kW design, that runs, but with a terrible power factor (copper losses and a huge differential reaction are killing the machine).
My question (eventually) is this: is this a viable proposition in motor design? Should I be looking at a different type of motor (such as a brushless DC or similar)?
Has anybody had any experience with a motor of this size?
Best Regards
