Abstract
A motor assembly having a field plate and a gear train mounted on at least one face of the field plate. The field plate defines an aperture which, in turn, defines a plurality of field poles for a rotor mounted in the aperture. A field coil is wound about a portion of the field plate to provide a motor for the field-plate-mounted gear train.
Claims13
A motor assembly comprising a substantially planar field plate having means defining a first aperture therethrough and defining a plurality of salient field poles, a permanently magnetic disc rotor mounted for rotation within said aperture, said rotor having an axially projecting drive shaft, first gear means mounted on said rotor, second gear means rotatably mounted on said field plate and being in driving engagement with said first gear means.
A sequential timer for controlling circuits of an electrical appliance comprising, in combination:
- (a) a sequencing cam having a plurality of tracks jointly defining a timing program;
- (b) a series of switches for connection in said circuits and controlled by said tracks;
- (c) a housing enclosing said sequencing cam and switches;
- (d) a motor for driving said sequencing cam;
- and
- (e) gear means drivingly connecting said sequencing cam and said motor;
- said motor having a field plate consisting of a portion of said housing.
