Abstract
According to the electromagnetic field theory, a set of differential equations is derived for coupling of the transient process for an electrical machine and transverse and torsional vibrations for the rotor by a unified method. A non-dimensional constant coefficient state equation is obtained by transformation. Computation is done. Rules of the change are obtained for transverse and torsional vibration, unilateral magnetic pull, electrical torque, and so on in the starting process. The theoretical results are shown to be in good agreement with the experimental results.
The mathematical model verified by the experiment is used to analyse the effect of electromagnetic and mechanical parameters on electromagnetic force and vibration.
