Hi
I am working on my M.Tech project. Now i need to identify whether other than brushless dc motor and permanent magent synchronous motor , is there any other possible motor which can drive a reaction wheel in a satellite.
please give suggestions

With today's power electronics and microprocessors, you can convert most types of electrical machines to high efficiency servo motors. Have you ruled out induction and reluctance motors?

It really depends on what you're looking to optimize. Efficiency? Power density? Cost?
