Electric Motors
Shop single-phase and three-phase electric motors from 1.5 kW to 7.5 kW for compatible compressors, pumps and industrial machinery.
Replacement Electric Motors for Compressors & Machinery
A replacement motor must match both the electrical supply and the mechanical arrangement of the driven equipment.
The current range includes 230 V single-phase and 400 V three-phase motors, with B3 foot-mounted and selected IE3 options.
Do not select by kW or HP alone — voltage, phase, speed, frame, shaft and mounting arrangement all matter.

How to Choose the Correct Electric Motor
Match both electrical and mechanical details to the original installation.
Power
Confirm kW/HP and driven load.
Supply
Confirm phase, voltage and frequency.
Frame & Mounting
Match frame size, foot centres and shaft height.
Shaft & Speed
Match shaft dimensions, keyway and motor RPM.
Electrical Supply Matching
Single-phase and three-phase motors use different supply and control arrangements and are not direct substitutes without wider system changes.
- Check 230 V single-phase or 400 V three-phase
- Confirm starter and overload arrangement
- Check capacitor requirements on single-phase designs
- Verify direction of rotation and connection method
Motor Speed & Pulley Ratio
On belt-driven compressors, motor RPM and pulley ratio determine pump speed.
- Match original motor speed and pole count
- Check motor shaft and pulley fit
- Maintain the intended pulley ratio
- Set belt alignment and tension correctly
Frequently Asked Questions
Can I replace a compressor motor using kW alone?
No. Voltage, phase, speed, frame, shaft and mounting must also match.
Can single-phase and three-phase motors be swapped directly?
Normally not without considering the electrical supply, controls and complete equipment design.
Can you help match a replacement motor?
Yes. Send the motor data plate, compressor model, shaft and mounting details.
