  • Traction Motor Repair

Traction electric motors are used to drive various equipment (electric trains, diesel locomotives, self-propelled cranes, trams and trolleybuses). The main differences between traction motors are related to the limited space in which they are located. The consequence of this was the specificity of the design (more compact dimensions, multifaceted frames, the presence of special devices for fastening, etc.). Electric motors for urban and railway transport must withstand significant operating loads, regardless of difficult weather conditions, as well as dusty and polluted air. Traction motors are designed to operate in a variety of modes (short-term, intermittent and intermittent with frequent starts). Current loads during vehicle propulsion can be 2 times higher than the rated ones. Since such electric motors are installed on passenger vehicles, they must meet safety requirements, in particular the requirements relating to explosion-proof electrical equipment.

Frequently asked questions

The repair time depends on the type: routine repair takes 1-2 days, rewinding takes 3-7 days, and overhaul takes 7-14 days. For urgent orders we work around the clock, and most jobs are completed within 1-3 days.

Yes. We provide a written warranty for all types of work: from 6 months for routine repairs up to 12 months for overhauls and rewinding. The warranty covers factory defects and errors in the repair performed.

Yes. We repair electric motors from any manufacturer — local (AIR, 4A, DAZO) and imported (ABB, Siemens, WEG, Mitsubishi and others). We use original spare parts or high-quality analogues.

Yes, an on-site visit by a diagnostic engineer is available in Tashkent and the Tashkent region. We will assess the motor's condition, perform initial diagnostics and draw up a work plan. The cost of the visit is discussed separately.

In most cases, repair costs 2-4 times less than buying a new motor of similar power. This is especially true for motors above 7.5 kW. See our article "Rewinding or a new motor" for a detailed comparison.

After the repair you receive: a certificate of completed work, a warranty card, and a post-repair test report (insulation resistance, no-load current, RPM). All documents can be handed over to your accounting department for asset registration.
