Increasing interest in environmental matters, a quiet motor are drastically demanded lately. Among of acoustic noise of the motor, electromagnetic acoustic noise is jarring and is studied recently. In order to reduce electromagnetic acoustic noise, it is necessary to design the motor, of which natural frequencies does not coincide with electromagnetic force frequencies. In order to avoid the resonance of the natural frequencies of the core and the electromagnetic force frequencies at designing phase, machine designer has to accurately predict these frequencies. In order to reduce the electromagnetic acoustic noise, this paper studies the following things, which are not clarified in previous research. Simulation method s of the natural frequency in rotor.
