ROTOR SYSTEM OF MAGNETOELECTRIC MACHINE Russian patent published in 2015 - IPC F01D15/10 F01D5/08 H02K1/32 H02K1/28 H02K1/27 

FIELD: machine building.

SUBSTANCE: rotor system of magnetoelectric machine contains a casing of the turbine block, shaft installed turbine, the shaft installed in bearings, a generator casing, a rotor. The rotor contains uniformly installed permanent magnets, magnetised in radial direction with alternating polarity. Turbine and rotor are installed on same hollow shaft, with possibility of coolant pumping through its cavity by the pump installed at the turbine side. At end of the hollow shaft a spiral channels are made. The hollow shaft with rotor creates a cylinder with permanent cross-section, on its external surface a bandage shell is installed out of high strength non-magnetic material. The bearings can be made in form of the contact-free gas supports, electromagnetic bearings or hybrid magnetic bearings.

EFFECT: minimised heating of the permanent magnets, and heat transfer between the turbine shaft and generator shaft, increased rigidity and mechanical strength of the system due to the generator shaft and turbine shaft making as single hollow shaft with possibility of the coolant pumping through its cavity, and spiral grooves making at the rotor end.
