Acceptance tests of the new TAD-650 traction asynchronous motor, developed specifically for use in high-speed electric train sets, have been completed at the production site of the Russkie Elektricheskie Dvigateli plant in Chelyabinsk. Based on the test results, the product's compliance with the declared technical and operational characteristics has been confirmed.
The TAD-650 model has a rated output of 650 kW and demonstrates a high level of energy efficiency, with efficiency reaching 96%. At the same time, the motor features compact dimensions and reduced weight of only 750 kg, which makes it competitive against foreign counterparts.
Plant specialists noted that in terms of the combination of parameters, including reliability, power consumption, and specific output, the domestic development matches the best global examples used in modern railway transport.
In the configuration of an eight-car high-speed train, eight such motors will be used. Powered bogies are planned to be installed under the first, third, sixth, and eighth cars, with two on each of them. The remaining cars will be equipped with non-powered bogies. Such a distributed traction system ensures uniform application of force along the entire length of the trainset, which has a positive effect on acceleration dynamics, ride smoothness, and energy efficiency of movement.
