Traction motors up to 1250 kW for locomotives and electric multiple units

Description

Traction motors are asynchronous electric motors for the traction drives of freight and passenger locomotives and electric multiple units (EMU). The company supplies motors with ratings up to 1250 kW and also manufactures special-purpose machines to customer requirements; each motor is designed for the operating conditions of the specific rolling stock. A traction motor must provide high torque at low speed, which is needed to accelerate the train and overcome inertia when starting from rest. The motors work over a wide speed range from the traction converter, adapting to the track profile, rail condition and energy consumption, and can be designed for different voltage levels for electric and hybrid rolling stock. According to the catalogue: rating up to 1250 kW, class F or higher insulation, high starting torque, forced cooling, standard and compact design. Copper alloy bars are used in the rotor, which improve conductivity, durability and reliability at high speeds and torques. Stators are impregnated with silicone-organic resin for operation in harsh conditions, with dust, water and snow. The manufacturer is certified by the Association of American Railroads to standard AAR M-1003. The manufacturer takes part in programmes of Indian Railways: the company supplies stators and rotors to a large corporation that performs the final assembly of traction motors for locomotives. Stators and rotors are manufactured at plants in Bangalore, with robotic lamination stacking, automatic insulation and impregnation. Applications: main-line and shunting locomotives, electric multiple units, and modernization of traction rolling stock.
