ABSTRACT:
An electromagnetic drive apparatus comprises a stator yoke excited with supply of power to a coil, a rotor arranged as capable of being driven by excitation of the stator yoke so as to move a driven member, and a fixed member for positioning and supporting the rotor and the stator yoke. The stator yoke has a projecting portion or a recessed portion and the stator yoke is positioned and supported relative to the fixed member by the projecting portion or the recessed portion to provide a compact motor without causing a drop of efficiency in the power of the motor.
