At the production site of the "Russian Electric Motors" plant in Chelyabinsk, acceptance tests of the new TAD-650 traction asynchronous motor, developed specifically for use in high-speed electric trainsets, have been completed. The tests confirmed that the product meets the stated technical and operational characteristics.
The TAD-650 model has a nominal power of 650 kW and demonstrates a high level of energy efficiency - the efficiency reaches 96%. At the same time, the motor is distinguished by its compact dimensions and reduced weight, amounting to only 750 kg, which makes it competitive against foreign counterparts.
Plant specialists noted that in terms of a combination of parameters - including reliability, energy consumption, and power-to-weight ratio - the domestic development corresponds to the best global models used in modern railway transport.
Eight such motors will be used in the configuration of an eight-car high-speed train. It is planned to install motor bogies under the first, third, sixth, and eighth cars - two on each of them. The remaining cars will be equipped with non-motor bogies. This distributed traction system ensures uniform application of force along the entire length of the train, which has a positive effect on acceleration dynamics, smoothness of ride, and energy efficiency of movement.
