Abstract
To accomplish conflicting goals of weight and noise reduction in a small motor, a plastic motor case with a flange is divided into two parts in the axial direction and an elastic body is mounted between the motor body and motor case so as to absorb vibration. A thin end bracket and motor housing can be used and not only for weight reduction but also for noise reduction can be realized.
