Investigation on Driving Force of Ball Bearing Motor

Article Preview

Abstract:

To study ball bearing motor working principle, an ingenious experiment was self-designed, which results indicated that the nature for driving torque of the ball bearing motor was thermal expansion rather than electromagnetic force as generally considered. Furthermore, the threshold current and cutoff temperature for the ball bearing motor were found in our experiment.
