Locomotive Systems
AC Propulsion
American Traction Solutions Inc. AC Propulsion Systems for Locomotives have been operating in daily service since 2013.
Features
- 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
Since 2008 years of operational experience, the ATS DC propulsion system is a proven solution for modern locomotive operations.
Features
