In Russia, the development of two traction asynchronous motors for promising railway transport has been completed almost simultaneously. Thus, TAD430 will be used in the new fully domestic two-section 16-axle 2TE35A main-line diesel locomotive with electric transmission, and DTA-380U1 is being created for the latest high-speed DC electric train "Ivolga 3.0".
TAD430 was created and tested for two years, but in the end, the design turned out to be reliable, and the motor itself is easy to maintain and unpretentious. Its weight is 2350 kg, efficiency is 96%. The release of a pilot batch of 160 asynchronous traction motors is planned for the current year.
2TE35A is designed for driving heavy trains weighing up to 7100 tons, its design speed will reach 120 km/h.
As for DTA-380U1, the pilot batch here will be larger – 1500 pieces. "DTA-380U1 is the first Russian traction electric motor that can provide train acceleration up to 1 m/s2 and speed up to 160 km/h," said Alexander Polikarpov, managing partner of the Rollingstock industry agency.
