ELECTRICAL MACHINE Russian patent published in 2014 - IPC H02K1/06 H02K21/12 

FIELD: electricity.

SUBSTANCE: invention is related to electric engineering and may be used predominantly for electrical machine constructions, and namely for AC electronic motors and synchronous generator with excitation from permanent magnets. The suggested electrical machine comprises a stator with laminated slots, multiphase armature winding and rotor with slots where permanent magnets are placed thus forming a system with alternating poles, at that active length L of the rotor is selected equal to (2.8-3.1)τ, where τ is polar pitch of the rotor.

EFFECT: improvement of power and dynamic performance of the electrical machine due to increase efficiency of active material usage.
