From standard off the shelf motors to one-off specials designed from scratch for an OEM, we have the motor to suit.

All of our standard stocked motors conform to IEC standards, meaning the mounting points are universal and the frame sizes will match your existing motor if it too is an IEC motor. All of our 3 phase electric motors are rated for use with an inverter.

Single-phase Motors - 110v or 230v

Single Phase motors run from either 110v or a 230v supply. They are supplied mostly into residential markets where the supply is 230v. Due to the fact these motors are a low volume item, they command a slightly higher cost than the equivalent 3 phase version. Single Phase Motors are available in two versions, permanent capacitor or capacitor start capacitor run. Due to the setting, they are used in and the maximum current available, Single Phase motors are usually only available up to 3kW. For more information, please visit this page 'Single Phase Motors'.

3 phase Motors - 415v or 690v

3 phase motors are widely available and are used throughout the world in industrial and commercial settings. All of the 3 phase motors we stock are 100% inverter compatible and have been thoroughly tested by our engineers. With power ratings from 0.25kW all the way through to 315kW, available for next day delivery and the added bonus of having technical support on hand or the ability to have the motor integrated into an inverter package or complete system, we are well placed to suit your requirements.

How do I Know Which Which Motor I Need?

If you are replacing an existing motor, the motor will usually have a metal plate attached. This plate will differ depending on the manufacturer, but will usually list all of the technical specifications of the motor. From this, we will be able to work out the main parameters and offer a replacement motor. If you can send us a photo we will send you a link to a replacement from our website. We may also need a photo of the motor as the nameplate does not always tell us the mounting type, in order to work this out we need to see the motor in situ.

Which Motor Have I got? Step by Step...

The two major differences in the motor are the supply, this will either be Single Phase or 3 Phase incoming supply. To check this we recommend isolating the motor first. Once this has been ascertained, the bullet points below will help determine which motor from either the 1P or 3P range you require.

Motor parameters required:
  • Speed (number of poles 2, 4, 6 or 8)
  • Frame Size
  • Mounting
  • Power (kW or HP)
  • Voltage
  • Any special requirements - Double shaft, force vent etc
