Abstract
A motor includes an electrically conductive yoke housing and a noise limiter circuit. The yoke housing is configured in an oblate cylindrical cup form having a couple of opposed flat side walls and a couple of opposed arcuate side walls that join opposed lateral edges of the flat side walls together. The noise limiter circuit includes choke coils. Each choke coil is arranged adjacent to a corresponding corner of the yoke housing located between a corresponding one of the flat side walls and a corresponding one of the arcuate side walls in such a manner that each choke coil extends substantially parallel to a central axis of the yoke housing.
