DEVICE AND METHOD FOR CLAMPING AND FIXATION OF CONSTANT MAGNETS AND IMPROVING COOLING IN ROTATING ELECTRICAL MACHINE Russian patent published in 2011 - IPC H02K1/27 H02K21/12 

FIELD: electricity.

SUBSTANCE: device intended to retain at least one constant magnet creating magnetic flow on surface of rotor of electrical machine during cooling of the machine, which contains at least one slot sunken from surface and spreading from one end of the above surface, and at least one clamping shaped element inserted at least in one appropriate slot having the projection projecting beyond the surface to come into contact at least with one magnet; at that, at least one slot and at least one clamping shaped element have the shape providing the possibility of retaining at least one clamping shaped element at least in one corresponding slot for retention at least of one magnet brought into contact on surface of the device.

EFFECT: providing reliable clamping and fixation of constant magnets on surface of rotor of electrical machine at simultaneous provision of the device for its cooling.
