Development and analysis of radial force waves in electrical rotating machines
Vibrations in electrical machines lead to undesired operating conditions and noise. The reasons lie in the design of the machine and the lack of precision in manufacturing. In order to avoid excessive vibrations, complex numerical analyses are carried out. This work deals with the development and analysis of electromechanical excitations in asynchronous machines with a short circuit rotor. The time-dependent electromagnetic forces acting on the stator bore are simulated with the method of finite elements. Subsequently, the force waves with respect to the frequencies and amplitudes are analyzed.
