|RELUCTANCE MOTOR WITH TOOTH PITCH STATOR WINDING|
|D. L. KALOUJSKI, A. M. STRIZHOV|
An inductor motor with the rotor without windings and stator with the multi-phase winding in its slots is investigated. The winding consists of alternating phase zones. The authors propose to use discrete Rademaher function to account whole the spectrum of space harmonics in equations of space magnetomotive forces. The methods of equivalent conductance and symmetrical components gave voltages equations, matrices of self and mutual inductance parameters. The matrices have (3m-4) elements. It distinguishes them from ones having 2 elements, that is typical for the most if electric machines. Hence, all symmetrical currents components including zero component effect on energy conversion, forming the torque. This cause higher noise and vibration if the motor is powered by the industrial network. The controllable mode gives possibility to vary levels of the fundamental and high harmonics of current. This allows to increase torque and to reduce electrical losses in windings.
