INDUCTOR MACHINE Russian patent published in 2014 - IPC H02K19/20 H02K19/06 H02K1/06 

FIELD: electricity.

SUBSTANCE: invention relates to electrical machines, namely to noncontact synchronous generators of inductor type operating mainly with rectifying load, used, for example, in generating units of motor-and-tractor machinery. The invention is aimed at overcoming of impossibility to use as the base the widely widespread and reliable asynchronous machines with a square-cage rotor. It is achieved by that the inductor machine, containing front, back covers, stator with a working winding, source of excitation, rotor with the shaft, according to the invention is equipped with a ferromagnetic sprocket with a central hole, the sprocket is located between a source of excitation and non-magnetic insert, which is attached to a cover, and each teeth of the star has threaded hole from the side part with fastened closing elements with a chamfer coupled connected with the stator.

EFFECT: use of the given structure allows on the basis of the initial asynchronous machine by adding of the source of excitation and details of the magnetic circuit to obtain the synchronous inductor machine, which has such a positive feature, that EMF is generated by the rotation speeds of the shaft from low up to rated one, while for operation in the mode of induction generator it is required to provide the rotor rotation higher than the rated speed.
