SYNCHRONOUS GENERATOR Russian patent published in 2014 - IPC H02K19/16 H02K1/06 

FIELD: electricity.

SUBSTANCE: invention refers to the sphere of electrical engineering. The proposed synchronous generator is designed for power characteristics of up to 1.5 kW/kg, higher efficiency factor of up to 95%, output voltage of 220/380 V and output frequency of f = 700 Hz. Separation of generating windings along the shaft in each section in the proposed generator makes it possible to increase the number of poles in the stator and the rotor. The proposed synchronous generator comprises a salient-pole stator with anchor winding and a rotor with poles that alternate in direction of the magnetic field. At the same time according to the first version of realisation the generator comprises N-sections arranged along the shaft, in each of which there is its section of the rotor and the stator with the anchor winding, each winding of the section covers all poles of the stator of its section, the rotor of each section is displaced relative to the adjacent one by 1/N period of alternation of the magnetic poles of the rotor. According to the second version of realisation, in the proposed synchronous generator the active sections of the anchor winding laid in slots between poles are made of steel plates, ends of which are connected by separate wires with ends of the plates of the adjacent slot in a mirror-like-symmetric manner relative to the pole between them.

EFFECT: increased output capacity of a synchronous generator with preservation of its dimensions.
