NON-CONTACT SYNCHRONOUS MACHINE HAVING SMOOTH ANCHOR WITH SLOTLESS ACTIVE ZONE AND CONSTANT MAGNETS ON ROTOR Russian patent published in 2009 - IPC H02K21/12 H02K21/22 H02K16/02 

FIELD: electricity.

SUBSTANCE: invention can be used for electric drives, for example in electric propulsion systems of sea vessels, submarines, in traction drives of ground electrically propelled vehicles, hoisting devices, drives of pumps, fans, electric tools, etc., at increased requirements for level of torque pulsations, vibrations, noises and with the possibility of supplying power to motors from typical bridge converters which are batch-produced.

EFFECT: improving operating properties, reaching high efficiency and reliability, simplifying machine design as a whole, providing unique low-level vibration and noise characteristics of electric drive on the basis of the proposed non-contact synchronous machine owing to using stator representing non-ferromagnetic cylinder formed of copper windings of slotless design and filled with special compound with high thermal conductivity, which is placed between cylindrical surfaces of internal and external parts of the rotor made from ferromagnetic material.
