Abstract Stator vibrations in permanent magnet DC motors have distinct characteristics which are also useful for analyzing other types of motors. The magnetic fields and the electromagnetic forces in permanent magnet DC motors were analyzed to characterize the physical mechanisms driving the vibrations. The order of the slot-frequency electromagnetic exciting force is not equal to the spatial order of the stator slot-frequency vibration shape. Accurate analyses of the vibrations inputs the magnetic field and electromagnetic force distributions calculated by finite element simulations into a structural finite element simulation to predict the stator vibrations. Experiments must have enough sensors to obtain the vibration mode shape. The predictions agree well with data from DC motor tests.
