LOW-SPEED GENERATOR OF STABILISED AC PULSES WITH STATOR OF GENERATING MODULES AND ROTOR WITH CONTROL SYSTEM BASED ON PERMANENT MAGNETS Russian patent published in 2010 - IPC H02K21/24 H02K21/12 

FIELD: electric engineering.

SUBSTANCE: invention relates to design peculiarities of low-speed generators of stabilised AC pulses and is intended for use in small power engineering as source of alternating current in case of emergency disconnection or full unavailability of power supply in composition of power generating using energy of natural events, operating in low-speed and unstable modes. In proposed end electric AC generator with stator assembled from coil groups fixed in its frame and rotor of two disks fixed on shaft and arranged near ends of stator and comprising magnetic system of permanent magnets, poles of magnetic system face stator coils, according to invention, the element that induces EMF in each stator coil is diametrically magnetised ball installed inside each coil, with the possibility of free rotation, from high-energy magnetic material (MB), magnetic fields of which may interact with magnetic fields of rotor. Specified MB turn at each step of rotor in planes that are radial to axis of its rotation clockwise or counterclockwise, depending on direction of rotor rotation. Each MB, rotating, induces EMF in coil, where it is located, being per se an independent rotor in each generating module of stator. Provided that time of each half-turn of MB is less or equal to time of each rotor step variation, magnetic system of rotor will set identical moment of MB rotation, stabilising EMF pulse induced by them.

EFFECT: simplified design, reduction of weight, dimensions and specific cost of power generating systems with provision of alternating current generation with required voltage in low-speed and uneven mode with efficiency factor comparable to traditional systems of electromechanical transformation.
