Abstract
A high speed electric motor for automotive applications that is designed to effectively minimize vibration of its component parts and thus suppress noise generated during its operation. The motor incorporates acoustic engineering principles including surface vibration control, acoustic radiation efficiency, active intensity field control and noise control using acoustic materials to reduce overall vibration of the motor components and the motor noise sensed by the passenger of the vehicle.
