ELECTRIC MOTOR, CONTROLLER THEREFOR AND METHODS FOR CONTROLLING AND ASSEMBLING SAME

摘要

A miniature electric motor (100) is provided including stator (110) and rotor (130) assemblies wherein the rotor assembly (130) has a magnet (134) and a shaft (138) adapted to be coupled to a load to move the load and wherein the magnet (134) is positioned about the stator assembly (110) for rotating without the stator assembly (110). The stator assembly (110) includes a stator (112) having a plurality of branches (120) made of a magnetic material angularly positioned with respect to each other and a plurality of coils (118) wound about their respective branches (120). The shaft (138) extends through the stator (112) and also, preferably, through a brake (146) which supplies pressure to the rotor assembly (130) to thereby supply a braking force to the rotor assembly (130) after the load has been rotated to a desired position.
