From our experience, the motor would have to meet specifictions, both
mechanical, and electrical.

You can call around to some of the electronics parts suppliers that
sell parts for servicing appliances and electronic equipment, but in
the end, they may have to order the same part as the one from the
origional manufacture.

The only other alternative you have is to get a scrapper microwave oven
that is if the same manufacture, and the same model, or the same for
its parts. Using parts from a scrapper unit, does not gaurantee that
the used replacement part will be reliable.
