Abstract
A bogie for a rail-based vehicle, such as a train or tram. The bogie comprises one or more rail wheel arrangements, each having two rail wheels. The rail wheels are driven by a motor arrangement, comprising one or more electrical motors. The operation of the motor arrangement is controlled by alternating signals provided by an inverter arrangement formed in the bogie. The inverter arrangements converts a direct current (power supply) to one or more alternating currents, or one or more alternating current power supplies, for controlling the torque applied by the electrical motor(s) of the motor arrangement.
