US Patent:

20100148605, Jun 17, 2010

Filed:

Dec 16, 2008

Appl. No.:

12/336370

Inventors:

Michael E. Moore - Haubstadt IN, US
Terry J. Stuckey - Evansville IN, US
Kawall Malhotra - Princeton IN, US
Randall R. Floyd - Evansville IN, US
John S. Bandas - Evansville IN, US

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

H02K 5/128
H02K 7/06

US Classification:

310 86, 310 80

Abstract:

An electric motor assembly includes a rotor rotatable about an axis and a stator spaced radially away from the rotor. An isolation housing, configured to permit magnetic flux to flow therethrough between the rotor and the stator, is disposed between the rotor and the stator and defines an internal rotor chamber, in which the rotor is located. The isolation housing fluidly isolates the internal rotor chamber from the stator. An encapsulating cover is provided that radially and axially surrounds the stator. The cover is formed of a resin material and bonds the stator to the isolation housing to prevent relative movement therebetween.
