US Patent:

46741780, Jun 23, 1987

Filed:

Aug 22, 1986

Appl. No.:

6/899258

Inventors:

Navinchandra R. Patel - Rockford IL

Assignee:

Sundstrand Corporation - Rockford IL

International Classification:

H02K 1514

US Classification:

29598

Abstract:

Loose or frayed fibers at the axial end of a fibrous wrap 42 about the periphery of rotor hub 10 mounting permanent magnets 22 are avoided by placing steps 40 between first and second diametral sections 36, 38 in side plates 32, 34 sandwiching the magnets 22 with the wrap preventing radial displacement of the magnets and the side plates preventing axial displacement.

Abstract:

In a dynamoelectric machine, a stator assembly is mounted directly in a bore of a housing for surrounding a rotor. The bore has an axially extending slot. The stator assembly includes a plurality of laminations bonded together in a stacked array for circumferentially surrounding the rotor. A given number of the laminations at one end of the stator assembly are radially enlarged to define a tab-like flange for projecting into the slot of the housing to prevent the stator assembly from rotating relative to the housing. Complementary axially abutting shoulders are provided between the stator assembly and the housing to prevent relative rotation therebetween.
