LINEAR ASYNCHRONOUS MOTOR Russian patent published in 2011 - IPC H02K41/25 H02K1/34 

FIELD: electricity.

SUBSTANCE: in linear asynchronous motor with open magnetic conductor containing the inductor consisting of core and multi-phase winding, and secondary element including the core in slots of which there arranged one under the other are at least two electrically conducting pins of secondary winding, thus forming vertical row, which are closed on one side with common electrically conducting bus; according to invention, each electrically conducting pin is connected to its electronic switching-control instrument connected to common electrically conducting bus closing electrically conducting pins on the other side and connected to multi-channel programmable control with feedback as to movement speed of secondary element.

EFFECT: enlarging functional capabilities of linear asynchronous motor with squirrel-cage rotor owing to providing the possibility of simultaneous voltage control on inductor and active resistance of secondary element by switching the number of active conductors in slot of secondary element.
