LOCOMOTIVE ANTI-SPIN DEVICE Russian patent published in 2009 - IPC B60L3/10 

FIELD: transport.

SUBSTANCE: wheel-anti-spin device comprises circuit including excitation windings and transistor connected in parallel. Other circuit comprises excitation winding and inductive shunt connected in series with the transistor, while the inductive shunt elements are shunted by diode. With wheel spinning, accumulated magnetic power in excitation windings restrains magnetic flux fall to prevent run-away spinning. The aforesaid inductive shunt connected, additional transistor allows smooth adjustment of traction motor excitation degree.

EFFECT: improved anti-spin properties, stabilised magnetic flux of traction motors, better traction and adjustment properties of locomotives.
