Abstract :
Two different ball-bearing motors have been investigated. The experimental results do not agree with the prevailing electromagnetic theories of ball-bearing motor operation. The results suggest that the driving force arises from an electromagnetic interaction between the ball race and the surface of the ball in the region of their contact point.
