Russia: A Chelyabinsk-based subsidiary of Transneft, Russian Electric Motors (RED), has completed testing of the prototype TAD330 asynchronous traction motors.
After successful acceptance, production of the pre-series of 50 units has been approved, to be followed by issuance of the Certificate of Conformity TR CU 001/2011 authorising serial production and operation.
The new 330 kW TAD330 motor is designed for two types of vehicles. The Lastochka EMUs operated by Russian Railways will receive them to replace Siemens Mobility motors. The other train is the new Finist, which is built by Ural Locomotives, a subsidiary of Sinara–Transport Machines, from 2023. “When manufacturing the new motors, experience gained in the production of power units for oil pipelines was used, as they have a number of identical components: stator, rotor and bearing units”, RED points out. According to the company’s website, the efficiency of the motors is at least 89%.
The TAD330 is an evolution of the range of electric traction motors manufactured by RED for rolling stock. The ATD1000 and the TAD430 motors have already been certified for the rolling stock produced by Sinara–Transport Machines. The former is designed for the ES8 mainline electric locomotive and the latter for the 2TE35A mainline diesel locomotive. Now, the TAD650 electric motor is also being developed for the Russian high-speed train project, with the prototype to be manufactured in 2025.
