ELECTRICAL MACHINE WITH DISC ROTOR Russian patent published in 2014 - IPC H02K21/24 H02K1/06 

FIELD: electricity.

SUBSTANCE: stator electromagnetic systems (EMS) of the electrical machine have a flat-topped shape with open poles facing the open poles of magnetic elements of the rotor, connected in pairs by magnetic bridges placed on the opposite side of the rotor relative the open poles of its magnetic elements. The distance between centres of poles of the stator EMS is equal to the distance between centres of poles of neighbouring magnetic elements of the rotor. The disclosed electrical machine has low material consumption of the structure owing to use of fewer magnetic elements in the stator EMS, simple technique of assembling and dismantling the structure owing to one-sided arrangement of the disc rotor relative the poles of the stator EMS, and the arrangement of the poles of the stator EMS in one plane enables to reduce the air gap between poles of the rotor and the stator, and the length of the middle magnetic line of the stator EMS, which considerably increases energy efficiency of the machine.

EFFECT: low material consumption and high manufacturability and energy efficiency of the structure of electrical machines with a disc rotor.
