This paper studies for influence of permanent magnet on the vibration at synchronous motor IPM SM with NdFeB and Ferrite magents two type which is same Back-EMF and output power have been desined. First, the dynamic simulation is performed with these two motors parameters. The current waveforms can be evaluated. And then based on the equivalent magnetization current principle, the magnetic force density and force including the tangential and radial direction components can be calculated. According to the relationship between the vibration and radial force, the vibration , and characteristic performs of these motors can be predicted. This result will give meaningful advice to the motor design.
