Review of Research in Japan on Electromagnetic Force Induced Vibration and Noise from an Electrical Motor

Abstract

An induction motor and synchronous motor are applied as a source of drive for machines such as power plants, home appliances and cars. Recently, electrical efficiency have been improved and mechanical structures have become lighter and smaller. As a result of these trends, mechanical vibration and noise are increasing. Vibration and noise caused by electromagnetic force must be reduced to provide a comfortable environment. To satisfy these needs, a system to simulate vibration and noise precisely and effectively at the mechanical design stage is needed. Such a simulation system would reduce the time needed for experimentation and reduce the length of development periods and costs of production.
