A second end cap is located adjacent to a second end of the stator assembly. An endbell is formed separately from the second end cap and is positioned within the second end cap. The endbell supports a bearing for a second end of the rotor shaft. An overmold material extends through the stator assembly. The overmold material may form the first end cap, supporting the bearing insert therein, and extends within and substantially fills an annular space within the second end cap.Type: GrantFiled: July 22, 2010Date of Patent: April 2, 2013Assignee: Globe Motors, Inc.Inventors: Daniel L. Kottmyer, Robert J. Marks

Patent number: 8405268Abstract: A stator comprises a ferromagnetic core having teeth. The stator also comprises first and second insulator members. The first and second insulating members collectively encircle each of the teeth of the core. The first insulating member comprising a plurality of mounting bosses spaced circumferentially from each other about the axis. Each of the mounting bosses has first and second retaining surfaces. The first and second retaining surfaces face axially opposite directions from each other and are exposed and are unobstructed by the second insulating member.Type: GrantFiled: February 18, 2010Date of Patent: March 26, 2013Assignee: Nidec Motor CorporationInventors: Daniel E. Bailey, Daniel E. Hilton, Gary E. Horst
