PLANETARY ELECTRIC MOTOR - REDUCER Russian patent published in 2007 - IPC H02K7/116 F16H1/32 

FIELD: electric engineering and electro-mechanical engineering, in particular, electric machines, particularly concerns features of structural realization of planetary electric motor - reducer.

SUBSTANCE: planetary electric motor - reducer contains body, positioned wherein are toothed gear wheel of planetary reducer and gear of planetary reducer, stator and rotor of electric motor, mounted eccentrically and connected to planetary reducer. In accordance to invention, in aforementioned device toothed gear wheel of first step of planetary reducer performs function of stator of electric motor, while gear of planetary reducer realizes function of satellite-anchor of electric engine, mounted on which is end collector with current-feeding and current-draining contacts, while end collector may move eccentrically relatively to body, toothed gear wheel - stator of electric motor has electromagnet coil and is made with internal engagement teeth, engaged with teeth of gear of satellite-anchor, having coils of other electromagnet, while teeth of internal engagement of gear of satellite-anchor are in contact with teeth of spindle, while aforementioned toothed gear wheel - stator of electric motor and gear of satellite-anchor of electric motor have grooves, positioned in which are coils of appropriate electric magnets, feeding of current into which creates torque and causes shift of satellite-anchor relatively to point of greatest mutual engagement of its teeth and teeth of toothed gear wheel - stator of electric motor, or relatively to contact point of friction couple formed by them.

EFFECT: improved mass-dimensional characteristics of planetary electric motor - reducer by means of combination of electric motor and planetary reducer in one structural unit.
