Abstract
A D.C. motor is disclosed having a magnetic plate disposed on the upper surface of the rotor for normally urging a rotor of the motor downwards. The spacing between the magnetic plate and a cover plate of the motor is made larger than the spacing of the rotor from the cover plate to ensure that the magnetic plate will not be unduly attracted to the cover plate.
