American Traction Systems (ATS) designs and manufactures high effeciency propulsion systems and accessories for Locomotives and MOW equipment. Our IGBT based choppers and inverters provide excellent wheel slip control, speed regulation and dynamic braking to zero speed.
ATS now offers the AC77 High Torque Traction motor. The AC77 allows the modernization of a legacy DC locomotive to more efficient and powerful AC traction for the fraction of the cost of a new AC locomotive.
