Claims

[Scope of utility model registration request]

A vehicle having two types of field windings, a direct-wound field winding and a separately excited field winding, and in which the separately excited field winding is excited from an overhead wire or a third rail via a thyristor chopper control device. In the traction traction motor, the separately excited field winding is configured to increase the utilization rate of the thyristor chopper device that controls the excitation current of the separately excited field winding, and to suppress inrush current when commutation fails. A field winding for a vehicle traction motor, characterized in that a device for increasing resistance is provided inside the traction motor.
