Combined induction-type electrical machine and braking arrangement

Abstract

A combined induction-type electrical machine and braking arrangement for use in a heavy vehicle comprises a stator configured to be coupled to a body of the vehicle, the stator comprising stator windings; a rotor configured to be coupled to at least one wheel of the vehicle, the rotor comprising rotor conductors; a configuration switching arrangement coupled to the rotor conductors of the rotor and controllable to switch between a first configuration, in which induced current flowing through the rotor conductors experiences a first total resistance, and a second configuration, in which the induced current experiences a second total resistance, higher than the first total resistance; and a controller configured to control the configuration switching arrangement from the first configuration to the second configuration in response to a braking command.
