Nothing is too strange, every challenge is solvable

Our value lies in what comes after the catalogue. In our Dordrecht workshop we modify motors to your exact specifications: IP upgrades to IP67, C5M maritime coating, shaft work, mounting conversion (B3 ↔ B5 ↔ B14 ↔ B35), insulation class upgrades, thermal protections and brakes. Per IEC 60034 and IEC 60079 for ATEX.

Protection class upgrades

Upgrade standard IP55 motors for harsher environments, within one working week.

  • IP66 / IP67 / IP68 conversion
  • C5M coating for maritime use
  • Tropicalisation & anti-condensation

Custom shaft machining

Our lathe modifies the shaft exactly to fit your drive line, often within 2-3 working days.

  • Shaft turning to required diameter
  • Build-up (welding + machining)
  • Shortening or extending

Mounting form conversion

Conversion between mounting forms so a new motor fits directly into an existing construction.

  • B3 → B14 or B35 conversion
  • 4-point suspension on request
  • Special flanges and adapter plates

Cooling & ventilation

Adaptation of the cooling method to your process, essential at low speeds or contaminated environments.

  • Conversion to TENV (totally enclosed, no fan)
  • Forced cooling (IC416)
  • External fan for low-speed operation

Functional add-ons

Additional components built in or fitted on per your specification.

  • Brakes (DC, AC, spring brake)
  • Encoders and PT100/PTC sensors
  • Anti-condensation heater, insulation upgrade

Like-for-like replacement

Send us your nameplate or photo, we supply a fitting alternative that needs no installation changes.

  • Identical dimensions and coupling pattern
  • Compatible with existing foundation
  • No installation modifications required

Electric motor repair near Rotterdam, own workshop, as-new warranty

Why overhaul instead of a new motor?

A reconditioned electric motor offers an attractive alternative for larger powers (typically above 30 kW). Benefits: substantially lower cost (typically 30-60% of list price), shorter lead time, proven mounting dimensions and full as-new quality documentation.

Pump motor repair and gearbox overhaul

Besides electric motors, Van Bodegraven also overhauling pump motors with special designs, vertical pump shaft motors, submersible pump motors (IP68) and combined motor-pump sets. For gearboxes we overhaul gear boxes, worm reducers and planetary reducers, including bearing, gear and seal replacement.

ATEX motor overhaul

For chemicals, offshore and oil sector we carry out overhauls on ATEX-certified motors. After overhaul we bring the motor back into conformity with ATEX 2014/34/EU and an Ex certificate is issued, essential for zone 1, 2, 21 and 22.
