摘要：

In order to evaluate the electromagnetic forces, the air-gap field is analysed. In the case of a periodical and phase balanced supply the radial and tangential force waves can be calculated analytically. When considering the deviations of currents caused by asynchronous pulsing, a numerical calculation will be necessary. By means of experimental investigations on the acoustic noise of a 1,5 MW motor the method of calculation is verified. In coordinating the numbers of phases, slots and poles the oscillating torques are eliminated and the acoustic noise can be minimized taking the vibrational behavior into account.
