ABSTRACT:
A rotating device such as an orbital motor has a stator which includes a pair of opposed, generally annular magnetic units each comprising a plurality of groups of permanent magnets such as ceramic or ferrous magnets arranged in a side-by-side relationship, each plurality being separated from an adjacent plurality by a magnetically permeable member, such as a malleable steel member or a malleable or molded iron member, to focus the lines of magnetic flux. A core armature is rotatably secured to a rotable shaft between the opposed pair of generally annular magnetic units for rotation therebetween. A commutator is fixedly secured for rotation with the armature coil and for receiving power supplied to or received from the motor and input electrical terminals. Preferably, each magnetic unit forms an annulus made from a plurality of arc-shaped permanent magnets, each having an inner face, an outer face separated from the inner face defining the axially-directed thickness of the magnet, an inner radial surface, and an outer radial surface separated from the inner radial surface defining the radially-directed thickness of the magnet. Each magnet also includes a pair of arcuately-displaced ends joining the inner face, the outer face, the inner radial surface, and the outer radial surface. The ends are in contact with intermediate T-shaped magnetically permeable members as described.
