Abstract
A control arrangement is described for dynamically braking a vehicle driven by an electric motor having a single field winding. The control arrangement comprises means for controlling the supply of power to the motor, a permanent magnet generator for mechanically coupling to the motor, and circuit closure means arranged to complete a circuit between the output of the generator and the field winding to dynamically brake the motor when the motor is de-energized by the controlling means.
