MODULAR ELECTRIC MACHINE Russian patent published in 2014 - IPC H02K29/00 H02K16/00 H02K1/06 

FIELD: electricity.

SUBSTANCE: modular electric machine comprises electromagnetic modules, which consist of two U-shaped cores arranged with their ends to each other so that ferromagnetic inserts on the rotor installed between two cores match in the projection with ends of each pair of two U-shaped cores. Electromagnetic modules are fixed along the circumference without radial displacement relative to each other, windings of the anchor are wound separately on each rod of the U-shaped core, which are arranged further from the machine shaft, and the excitation winding is made toroidal, common for all electromagnetic modules of each fixed part of the stator, as a result of which rods of U-shaped cores that are close to the machine shaft are arranged tightly to each other, which results in maximum reduction of distance between electromagnetic modules. At the same time anchor windings of one phase displaced by a pole division are connected as matching in series.

EFFECT: provision for reduced diameter of a machine and torque pulsations, simplified design of a modular machine, which makes it possible to implement different machine versions in one design for various voltages and currents, provision of the possibility to section anchor windings and to increase reliability, increase capacity in radial and axial directions.
