An efficient motor is designed to keep the magnetic field inside.

Perhaps it is made of a non-ferrous material?

The yoke/frame is generally made out of a metal with poor magnetic properties. Is this an AC or DC machine?

I've only heard the term "yoke" used (in motor context) with regard to DC motors.

Is there any current flowing in the yoke? A single broken wire could be responsible!

That would, of course, be a mechanical failure. After all, the electrons are willing but they can't just ignore a broken bridge. That is why I maintain that there is no such thing as an electrical failure. Electrical people have to do twice the work. Before the electrical problem can be fixed, the mechanical failure must first be identified.
