Extend the life of your equipment.

Expert maintenance and performance restoration for KOMAX submersible motors, using original design blueprints and factory-grade components.

Minimising downtime with factory support.
Precision maintenance by industry experts

Minimising downtime with factory support.

Our ISO 9001 certified facility and engineering team restore your equipment to its original factory efficiency — whether it is a routine overhaul or a critical breakdown.

  • Skilled technicians: certified experts with years of submersible motor assembly experience.
  • Factory-grade materials: premium rewindable winding wire with PVC / PE2 / PA insulation.
  • Specialised factory support: as the original manufacturer we use official blueprints to restore “as-new” performance.
Comprehensive testing and analysis

A scientific approach to motor restoration.

  1. Failure analysis & diagnostics

    We record every motor failure and advise you on preventing future issues from voltage spikes or hydraulic loading.

  2. Precision rewinding

    Our in-house automatic winding plant rewinds to the motor’s original power factor and amperage draw.

  3. Full-load performance testing

    Every repaired unit is tested on our dynamometers (IEEE 112 Method A) for a Pass/Fail result before it returns to the field.

Beyond repair

Upgrade the motor while it is open.

If a motor failed because of its environment, we can modify it during the repair.

01

Metallurgical upgrades

Convert standard components to 316 stainless steel.

02

Thermal protection

Install PT100 sensors for real-time temperature monitoring.

03

Voltage adaptation

Modify the stator for regional power grids (50 Hz vs 60 Hz).

When to repair vs. replace

Common rewinding questions.

How do I know if my motor needs a stator rewind?

We perform an insulation resistance test to determine whether the winding is damaged.

Does rewinding affect motor efficiency?

When it is done in a factory setting like KOMAX with premium wire, efficiency stays at peak levels.

What is the lead time for a standard repair?

Our automated production line gives us some of the fastest turnaround times available. Contact us with the motor model for a firm date.
