A Study on vibration of slim type Permanent Magnet Synchronous Motor for driving elevator

Electromagnetic system of motor is being minimized by superior magnetic material and advanced design technology. But this type of motor causes a serious vibration. This is a big problem of motor operation. To decrease a vibration, motor is need to be designed considering mechanical vibration. This paper study about torque, natural frequency and mechanical vibration according to displacement.
