Abstract: A motor is provided for use in a machine. The motor includes a segmented stator and a resiliently flexible clip. The stator includes a core having spaced apart arms and a yoke. The arms define an opening therebetween, and the yoke spans the opening. The clip is removably retained on the core so as to apply pressure against each arm toward the yoke such that the arms are retained in contact with the yoke.

Abstract: A stator of an electric motor or generator comprises a core formed of ferromagnetic material having a plurality of teeth arranged circumferentially about an axis. In one aspect of the invention, at least one retaining member connects the end portions of at least two of the teeth to each other in a manner inhibiting relative movement between said tooth end portions. By inhibiting relative movement between said tooth end portions, vibration is reduced. Vibration can also be reduced by welding interior surfaces of a core to each other. Reducing the vibration reduces the noise emissions of the stator during operation.
