Simulation study on rotating radial electromagnetic force for use in dynamic balancing

A tentative idea of introducing rotating electromagnetic force for dynamic balancing is presented in the paper. A method of generating the force is put forward, the force generated has adjustable magnitude, speed and phase angle. Working characteristics of the force are analyzed. Phase windings fed with half sine currents are designed to restrain pulsation of the force vector in space. Simulation results of a model indicate that a rotating force vector can be obtained by selecting a proper number of phases simultaneously fed with currents, which is able to meet the needs of ordinary engineering problems.
