Asynchronous motor repair at SPEC SERWIS means comprehensive repair work carried out so as to restore drive functionality as quickly as possible and limit production downtime. We deal both with the rectification of sudden failures and with planned overhauls of motors critical to maintenance.
Professional asynchronous motor repair for industry
We repair industrial asynchronous motors used in conveyors, pumps, fans, mixers, packaging lines, sorters and other process machines. We work both with individual motors and with drives integrated with gear units and frequency inverters.
We combine service experience with practical knowledge of drive operation in difficult working conditions – from the food industry and waste management to logistics and automated warehouses. Thanks to this, we can quickly diagnose the cause of a fault and select the optimal repair scope.
Scope of repair work
Within the “Asynchronous motor repair” category, SPEC SERWIS offers, among other things:
- detailed electrical and mechanical fault diagnosis (winding insulation, measurements, vibration, temperature, bearing condition),
- mechanical repairs: replacement of bearings and seals, shaft refurbishment or replacement, rotor balancing,
- overhauls of the electrical part: stator rewinding, repairs after overheating or flooding, restoration of catalogue parameters,
- cooling system repairs (fans, covers, cleaning of cooling ducts),
- repairs and adjustments of drives with a frequency inverter (parameter selection, error analysis, setting corrections),
- modernisations accompanying the repair – selection of better bearings and seals, changing the starting method, restoring compliance with the manufacturer's documentation.
Depending on the condition of the machine, we propose a routine repair, a partial overhaul or a general overhaul of the asynchronous motor.
The asynchronous motor repair process
To make maintenance planning easier, the repair process at SPEC SERWIS is as structured as possible:
- Report and initial consultation – we take the basic data from the name plate, the description of symptoms and operating conditions, and agree the mode of execution (standard or urgent).
- Disassembly and transport – depending on the situation, we disassemble the motor on site or accept it delivered by the customer; if necessary, we organise transport.
- Diagnosis and quotation – we carry out a detailed inspection and measurements, and prepare a report with the cause of the damage and the recommended repair scope together with a cost estimate.
- Repair execution – we carry out mechanical and electrical work, replace worn elements, perform rewinding if needed, assemble the motor and prepare it for testing.
- Final tests and acceptance – we carry out test-bench trials (checking heating, vibration and operating current), after which the motor is ready for installation at the customer's site, together with the handover of the repair documentation.
This scheme makes it possible to clearly define the time and scope of work, and to assess in advance the cost-effectiveness of the repair compared with purchasing a new motor.
Why entrust the repair to SPEC SERWIS
SPEC SERWIS specialises in industrial drives and geared motors, which is why we always treat asynchronous motor repair as part of a wider drive system, not an isolated case. In practice, this means:
- many years of experience in repairing motors and drives from leading manufacturers,
- knowledge of typical faults in specific applications (conveyors, pumps, fans, agitators),
- access to high-quality spare parts and consumables,
- the ability to carry out a parallel assessment of the gear unit and frequency inverter working with the motor,
- flexible turnaround times, including an accelerated mode for drives critical to production continuity.
As a result, the customer receives not only a repaired motor, but also recommendations on how to reduce the risk of similar failures in the future.
FAQs – asynchronous motor repair
Below we have gathered answers to the most common questions related to asynchronous motor repair. They will help you better plan service work and assess the cost-effectiveness of an overhaul.
What symptoms indicate that an asynchronous motor needs repair?
Worrying signals include excessive heating of the housing, a marked increase in noise and vibration, tripping of protections, a drop in torque or uneven running. If discolouration from overheating or traces of oil or grease around the seals are also visible, it is worth commissioning a diagnosis as soon as possible – at this stage a cheaper, partial repair is often still possible.
How long does a typical asynchronous motor repair take?
The repair time depends on the scope of work and the availability of parts. Simple mechanical repairs (e.g. bearing replacement) can be completed within a few working days, while general overhauls with rewinding and additional testing can take longer. For drives critical to production, we strive to carry out the work in an accelerated mode, after agreeing the deadline in advance.
Is repair always worthwhile, or is it better to buy a new motor?
Not always. That is why, before starting work, we prepare a quotation and compare the cost of repair with the cost of buying a new motor of comparable parameters. If the overhaul is to be close in price to a new unit, or there is a risk of further failures, we recommend replacement with a new unit. The final decision is made by the customer, with a full picture of the costs and risks.
Can you collect a damaged motor from my plant?
Yes, in many cases we organise disassembly and collection of the motor directly from the customer's plant. The scope of logistical support (disassembly, loading, transport, re-installation) is agreed individually at the reporting stage. Thanks to this, the maintenance department does not have to organise all the drive-related work itself.
