Hi There,
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

Ings overlap and each winding slot has two windings in it usually from different phases. (See 4 and 6 pole distri-butions on the handout from class.) Here I assume a two pole distribution because it makes the explanation eas-ier. Such a motor runs at the nominal speed range of 3500 – 3580 RPM. (Four and six pole motors run at 1720 to. An optimal stator and rotor pole numbers until 1. Feasible combinations for a three-phase FSPM machines with magnets are given in (1) 1. N s =6k 1,k 1 ∈ N∗ N r = N s ±k 2,k 2 ∈ N∗ (1) N s is the slot and magnet numbers, which must be even and N r is the rotor pole number. Thus, for a 12-slot machine, any rotor could potentially be.
