LINEAR VALVE INDUCTION GENERATOR MOTOR Russian patent published in 2010 - IPC H02K41/03 H02K16/00 

FIELD: electricity.

SUBSTANCE: invention is a machine (linear valve induction generator motor) that can equally operate as a generator and as a motor and possesses a number of characteristics allowing optimisation of weight and power ratio as well as production costs. The machine concerned has several air clearances crossed by a single magnetic flux wherein magnetising force is formed. The flux is generated by a series of coils (6) arranged on active parts The active parts are two frames (4) and (5) whereon the magnetic flux is grounded. In the above magnetic circuits other active parts may exist wherethrough the magnetic flux grounding fails to occur. A series of passive elements (habitually represented by transducers (1) and (2)) in the course of their motion relative to the active parts cause change of the circuit magnetic with respect to the position causing magnetic force. The most unique feature of the invention consists in the magnetic flux returning through only two butt-end active parts (4) and (5).

EFFECT: reduction of stray flux at the poles of the proposed generator motor and reduction of its mass, weight and cost.
