Analytical study on the acoustic noise reduction method of the permanent magnet motor

Abstract

Motor applied to the vehicle as shown in traction motor (inwheel, inline) and MDPS (Motor Driven Power Steering) has been newly developed in various ways to deal with this in the energy depletion and environmental regulations. In addition, improvement efforts are also underway in the range of related issues are constantly raised issues related to noise and vibration in the motor vehicle becomes increased. In this paper, we pick up the contents of motor, the noise and vibration, was conducting research into noise and vibration reduction through the Force analysis of the stator slot as an approach for improvement and their causes, and trying to prove its validity through comparison with actual experimental data.
