CONTACTLESS ELECTRICAL MACHINE Russian patent published in 2006 - IPC H02K1/16 

FIELD: electrical engineering.

SUBSTANCE: proposed electrical machine that can be used in off-line electrical equipment as dc or ac power supply (dc or ac thyratron generator) and also as electromechanical dc or ac thyratron motor has stator whose teeth carry m-phase winding and rotor with 2p alternating poles. Stator tooth number z is a multiple of phase number m, z number and rotor pole number 2p are chosen to provide for |I| > 1 difference between them; m-phase winding is wound so that direction of turns on stator teeth within coil group is alternating and slot opening angle α_s depends on design and engineering restrictions as function of z chosen from equation

EFFECT: reduced specific loss, reactive torque, and mechanical noise in motor.
