Abstract
The invention provides for a motor attachment assembly that includes an electric motor having spring clips adapted to securely lock onto the isolation posts of a plastic post vibration isolation system. The motor includes an end cap that has notches which cooperate with locator tabs of the motor housing to lock the cap onto the housing with the spring clips therebetween. Each clip includes an axial slot that is expandable in an open direction to receive an isolation post and biased in the closed direction to retain the isolation post. Each clip also has an inner surface with barbs protruding into the channel to allow insertion of the isolation post into the channel in the direction of the output shaft and to resist movement of the isolation post in a direction opposite to the output shaft. The inner surface has a retention groove to receive plastically deformed portions of the isolation post.
