A NEW APPROACH TO THE ANALYSIS OF ELECTRICAL MACHINES WITH ELECTROMAGNETIC SPEED REDUCTION

A new approach has been used for the analysis of physical processes in electrical machines with electromagnetic speed reduction. It has been shown that a magnetic conductance wave revolving in space with a spee d considerably exceeding the speed of the rotor is produced in machine s with a developed bilateral tooth arrangement. For its synchronizatio n with the fundamental harmonic of the stator m.m.f., the speed of the rotor must be many times lower than the speed of m.m.f, rotation. Fea tures of the physical processes in various types of machine with elect romagnetic speed reduction have been considered.
