A drive system includes an engine, an alternator coupled to the engine, the alternator being configured to power at least one auxiliary load, a traction motor system operatively coupled to drive wheels of the vehicle, the traction motor system being configured for receiving primary electrical power from the alternator and for propelling the vehicle in response to the primary electrical power, and a motor electrically connected to the traction motor system and mechanically coupled to the engine. The motor is configured to receive electrical power from the traction motor system in a dynamic braking mode of operation of the traction motor system and to communicate power to the engine during the dynamic braking mode.

System and method for reducing fuel consumption in a vehicle

A system (for controlling cooling of an alternator) comprises a control system, an alternator, and a blower fan, the alternator having a stator and a rotor. The control system is adapted to estimate one or more temperatures of the stator and/or rotor of the alternator using a thermal model. The control system is also adapted to control the blower fan to cool the alternator by providing a specified amount of air flow across the stator and rotor of the alternator, based on the estimated one or more temperatures of the stator and/or rotor.

Method and system for alternator thermal protection

Various systems and method for generating electrical power in a rail vehicle are provided. In one embodiment, a vehicle system includes an electrical power generation unit operatively coupled with a drive shaft of an engine. The electrical power generation unit includes a fraction alternator and a head-end-power (HEP) alternator. The traction alternator is excited by power electronics positioned external to the traction alternator. The HEP alternator is self-excited by an exciter winding positioned in the HEP alternator.
