An improved actuator assembly is disclosed. The actuator has a rotor assembly rotatably mounted in a stator frame formed of a synthetic resin material. The stator frame has a borehole therein that receives a rotor assembly, a pair of mounting recesses, and a pair of bobbins portions. Each bobbin portion includes a slot. Induction magnets are mounted in each mounting recess of the stator frame such that they face the rotor assembly. A coils is would about each bobbin portion of the stator frame. The coils and induction magnets are angularly spaced about the rotor assembly. A core having a plurality of poles and holding portions, is also provided. Each core pole extends through an associated one of the bobbin slots and faces the rotor magnet. The holding portions are arranged to hold the induction magnets in place.
