MODULAR UNIVERSAL ELECTRIC MACHINE BY BELASHOV Russian patent published in 2010 - IPC H02K23/66 H02K23/54 

FIELD: electric engineering.

SUBSTANCE: invention is intended for use in any fields of economy as DC generator, single-phase or multiphase DC generator, high-speed or slow-speed DC machine, single-phase or multiphase AC motor, welding AC or DC machine, metering device, voltage and current converter. Modular universal electric machine comprises body with even and uneven number of modules. Each module includes detachable shaft joined to support bush via connecting element installed on rotor with magnetic systems and magnetic conductors, which interacts with stator, having multiturn windings, closed collector with contact plates, electronic commutator and brushes conducting current, which are electrically connected to system of automatic tracking and control. System of automatic tracking and control additionally comprises intelligent unit, including a system of input metering devices, which are installed inside stator. System of input metering devices is arranged in the form of Hall sensor, frequency sensor, inductance sensor, voltage sensor, current sensor and temperature sensor. Metering devices interact with comparators, controller of sensitivity and proportionally-integrally-differential controller, having unit of power supply, integrator and logical devices, which generate signals of control coming to output devices, object of control. Output devices are installed in shoe to supply and remove voltage, having transistor or symistor optical isolators joined to control relay. Control signals arrive to commutator, and via adapter of communication interface, to personal computer, which includes system of data registration, system of diagnostics and control, system of automatic tracking and control over technological process, system of correction, programming and protection of settings. On outer base of support bush, via connecting element, there is a fixed and movable disk of rotor installed with end fixing facilities, which interact with rotor stands via fixation elements. Support element of swinging or sliding is located at movable disk of rotor and interacts with stator, which is fixedly installed between stand of stator, bush of stator and pressing plank. Besides number of rows of multiturn windings must correspond to number of rows of rotor magnetic systems, and multiturn windings of stator and magnetic systems of rotor must have specified angular motion.

EFFECT: improved efficiency coefficient, reliability, safety and manufacturability of modular electric machine with simultaneous expansion of its functional resources.
