Resilient isolation members and related methods of reducing acoustic noise and/or structural vibration in an electric machine
First Claim
1. A resilient isolation member for an electric machine having a housing, a stator within the housing, and an end shield, the resilient isolation member comprising a first end portion, a second end portion, a sidewall extending between the first and second end portions, and a lip disposed along an outer surface of the sidewall, the resilient isolation member being sized for mounting between the end shield and the stator, with the first and second end portions respectively abutting against a first inner portion of the end shield and a portion of the stator and with the lip abutting against a second inner portion of the end shield and a portion of the housing.

Abstract
A resilient isolation member is configured for use with an electric machine having a housing, a stator within the housing, and an end shield. The resilient isolation member includes first and second end portions, a sidewall extending between the first and second end portions, and a lip is disposed along an outer surface of the sidewall. The resilient isolation member is sized for mounting between the end shield and the stator, with the first and second end portions respectively abutting against a first inner portion of the end shield and a portion of the stator and with the lip abutting against a second inner portion of the end shield and a portion of the housing.
