초록

The mechanical unbalance of the rotor in motors generate vibrations and make its shortened their life, therefore, it is important that search for a cause of the vibration in the point of economics. In this paper, to reduce the vibration we will analyse the unbalance magnetic pull in induction motor. Namely, the electromagnetically generated forces, the airgap flux density distribution in a single phase induction motor is calculated by analytical and numerical method.
