ABSTRACT:
A stack assembly is disclosed of the type used in linear brushless DC motors, the stack assembly having a base portion, a plurality of teeth extending from the base portion and about which the windings can be positioned, and in which the plurality of teeth are spaced apart from each other so as to define slot openings at ends of and between adjacent teeth, and magnetic material shaped and positionable to enclose one or more of the slot openings between adjacent teeth. Also disclosed is a mounting bracket positionable along the back iron of the stack assembly and shaped so that the ends of the mounting bracket engage with the ends of the stack assembly.
