ELECTRO-MECHANICAL RAIL DRIVE WITH GEAR RAIL Russian patent published in 2018 - IPC B60L13/03 H02K41/03 

FIELD: electricity.

SUBSTANCE: electro-mechanical rail drive with gear rail includes electromagnets attached to the trolley and switching devices of electromagnetic windings. On the gear rails the teeth are made in the form of rail poles, analogous to the poles of electromagnets. Near the pole of the electromagnet there are sensors for the position of the rail pole connected by their outputs to the inputs of the control device. The outputs of the control device are connected to the inputs of the switching devices, which connect the electromagnetic windings to the power supply. The output of the traction and braking control device is connected to the other input of the control device. Next to the electromagnet there is attached to the frame of the trolley a retainer containing a pin.

EFFECT: increase the reliability and efficiency of the electromagnetic rail drive.
