Modular motor

Abstract

A small motor assembly is shown which requires little, if any, hand work for assembly. A terminal assembly is associated with the magnetic frame and held in place by the field coils. The terminations of the field coils are connected to selected terminals of the terminal assembly. An end bracket which supports an end bearing for the armature and brush holders is secured to the terminal assembly to provide a complete motor assembly. The brush holder is secured to the end bracket by a plurality of protuberances which mate with slots in the end bracket. The brush holder has formed thereon a projection which makes connection with a predetermined terminal on the terminal assembly when the end bracket is secured to the terminal assembly. The brush holder may be secured to the end bracket in a plurality of positions thereby causing its projection to make a connection with different predetermined terminals on the terminal assembly. The particular selected position for securing the brush holder to the end bracket and the consequent change of terminal contacted by the projection from the brush holder can influence the direction of rotation of the armature. The brush and brush spring may be assembled in the brush holder after the end bracket is secured to the terminal assembly. The brush and spring may be captured in the brush holder by bending an end wall into position after the brush and spring are assembled in the brush holder. At an appropriate time, wires for connection to a power source may be inserted into appropriate terminals of the terminal assembly.
