Locomotive Systems
AC Propulsion
American Traction Systems AC Propulsion Systems for Locomotives have been operating in daily service since 2013.
Features include:
- Independent axle control – one inverter per motor
- Wheel Slip Control algorithm that compensates for wheel wear
- Operates at or near break down torque of the motor across the entire speed range
- Rotor temperature compensation algorithm
- Fully-integrated dead band compensation of the IGBT firing circuit
- Brake Chopper that can be used as a machine load bank
DC Propulsion
With a over 25 years of operational experience, the ATS DC propulsion system is a proven solution for modern locomotive operations
Features include:
- Motor thermal overload protection
- Adjustable overcurrent protection
- Automatic wheel slip control
- Optional Field Controller eliminates reversing contactors
