Patent number: 9391493Abstract: An electric machine includes a stator having a first end and a second end and an end frame including a first cup portion arranged to at least partially contain a portion of the stator. The end frame is positioned adjacent the first end of the stator. A potting cup includes a second cup portion arranged to at least partially contain a portion of the stator. The potting cup is positioned adjacent the second end of the stator. A potting member is coupled to the stator, the end frame, and the potting cup to permanently bond the end frame, the potting cup, and the stator to one another.Type: GrantFiled: August 23, 2013Date of Patent: July 12, 2016Assignee: Regal Beloit America, Inc.Inventors: Ngan Fai Leung, Stephen Thomas English, Matthew William Critchley, Janice Fitzgerald, Frank Edward Staigl, III, Joseph Henry, Barbara Mary Shanks, John R. Belko

Publication number: 20130342051Abstract: An electric motor assembly. A stator includes a set of windings and has a first end, a second end, and an outer radial surface. A rotor includes a shaft having an axis. A first frame supports the shaft at a first axial position. A canopy substantially surrounds the first frame. The canopy includes a fluid inlet and a fluid discharge. A second frame supports the shaft at a second axial position and includes at least one fluid outlet. A chute is positioned downstream of the canopy fluid discharge. The chute directs fluid flow along the outer radial surface of the stator towards the fluid outlet. A fan is coupled to the shaft downstream of the fluid outlet for rotation with the shaft.Type: ApplicationFiled: August 23, 2013Publication date: December 26, 2013Applicant: Regal Beloit America, Inc.Inventors: Ngan Fai Leung, Stephen Thomas English, Matthew William Critchley, Janice Fitzgerald, Frank Edward Staigl, III, Joseph Henry, Barbara Mary Shanks, John R.

Patent number: 8497611Abstract: An end-frame of an electro-dynamic machine includes a bearing housing defining an annular bearing cavity for rotatably supporting a rotor shaft about an axis. A support body is coupled to the bearing housing. The support body has a terminal end and a base end opposite the terminal end. The base end includes a first radial support surface having a first diameter, a second radial support surface having a second diameter, and an annular wall axially disposed between the first radial support surface and the second radial support surface. A radial extension extends radially from the support body adjacent the terminal end. A mounting member extends axially from the radial extension portion. The mounting member defines an aperture for receiving a BX fitting.Type: GrantFiled: April 22, 2011Date of Patent: July 30, 2013Assignee: Regal Beloit America, Inc.Inventors: Ngan Fai Leung, Frank Edward Staigl, III

Patent number: 6882070Abstract: An electric motor including having a housing, a stator fixed relative to the housing, a shaft rotatable about a motor axis, a rotor supported by the shaft for rotation with the shaft relative to the stator, a terminal board fixed relative to the housing, and first and second electrical terminals supported by the terminal board. The electric motor also includes an operating condition selection device including a moveable portion supported by the terminal board for pivotable rotation about a second axis between a first position corresponding to a first operating condition and a second position corresponding to a second operating condition. At least a portion of the moveable portion substantially remains in a fixed axial position relative to the second axis while pivoting between the first and second positions. The electrical terminals are accessible through a conduit receiving aperture for testing purposes.Type: GrantFiled: April 1, 2003Date of Patent: April 19, 2005Assignee: A. O.
