  • Rotor Rewinding

High-quality, timely repair of the electric motor rotor will maximize its service life, minimizing the likelihood of breakdowns. The structural complexity of this equipment requires special attention to professional repair. Below we will look at how to repair and rewind an electric motor rotor, briefly outlining the features of the services offered, while recalling the types of electrical installations.

Repairing an electric motor rotor - key steps

Qualified performance of repair of rotary electric. enginewill provide factory efficiency, restoring the original functionality of the device. To achieve impeccable quality, our craftsmen strictly observe all the details of technological operations in accordance with the technical instructions of the manufacturer of a specific model of installation. Only experienced specialists can repair the electric motor rotor, guaranteeing no breakdowns and a long uninterrupted operating period, subject to operating rules.

Regardless of the selected type of service, rewinding an electric motor rotor involves the following operations:

  • dismantling and disassembling of the electrical installation;
  • removal of old windings and failed mechanisms;
  • restoration of insulating layers, windings, lamellas and other parts;
  • replacement of bearings with subsequent painting of the housing;
  • assembly of electrical. motor;
  • visual assessment of winding quality;
  • final diagnostics of the device.

It is worth understanding that the exact list of steps depends on the degree of damage and customer requirements. We offer a full range of repair services, including, in addition to motor rewinding and motor rotor repair, restoration of explosion-proof models after complex emergency situations.

Types of repair services

  1. Routine repair of the electric rotor. engines is carried out in order to eliminate various malfunctions, by replacing or restoring (if possible) damaged elements.
  2. Technical - implies a routine check of the functionality of electrical equipment. If necessary, the electric rotor is rewinded. engine, as well as restoration of failed components.
  3. Urgent - performed in emergency cases and in the shortest possible time. The cost of rewinding the electric motor rotor in this case is higher due to unscheduled work. Major - involves the complete restoration of the electric motor rotor with a detailed check of each structural element. This approach ensures maximum efficiency and functionality during long-term operation.

Types and features of serviced electric motors

  • Crane electric machines are used in the design of lifting equipment and cranes. They are distinguished by a closed explosion-proof housing at high frequencies and magnetic fluxes, which ensures maximum overload capacity. By type of power supply, installations can be either AC or DC.
  • High-voltage traction motors are adapted to harsh operating conditions at extreme conditions. Powerful units are designed to drive vehicles and industrial equipment. Despite the massive design, the stages of repairing the rotor of an electric motor of this type are similar to those for repairing other versions of machines.
  • Elevator installations are used to drive winches and elevators. The line of these machines is distinguished by a large list of modifications, including brushless versions, as well as synchronous and asynchronous models. Rewinding of the rotor of an electric motor of this type can be carried out at the site of operation of the equipment. Rotary motors can be either three-phase or single-phase.

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.
