3 Phase AC Motors

3 Phase motors are more compact and run more smoothly than their single phase counterparts while providing nearly twice the power. All of the 3 phase motors we list adhere to the latest European mechanical and electrical standards to ensure safe operation for the life of the product.

Our range of motors can rotate at speeds of up to 3000 RPM (higher for short periods depending on load) and we offer a variety of options for mounting. Water and dust tight cooling fans mean the operating conditions can be preserved inside the unit in most working environments. Our motors come as standard with Class F insulation. Our AC Motor range are all Inverter rated Motors, so can be used with any of the inverters we supply.

We have access to the largest stock of AC Motors in the UK, so we can provide a motor of up to 315kW on a next day service if required. If you require any assistance selecting your motor, please call us, we use these motors every day in our project and service work, call our team on 01905 887 667.

Which Motor Do I Need?

If you are replacing an existing motor, the motor will usually have a metal plate attached. This plate lists all of the technical specifications of the motor. You can send us a photo of this if you cannot nterpret it, and we can spec a replacement motor to suit for you.


Motor Plate

The basic parameters we need are as follows:

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

How Many Poles does my Motor Have?

A motors base speed is usually determined by the number of poles it has. The less poles, the higher the maximum speed, with more poles, the speed decreases, but the torque produced by the motor increases. The table below is a rough guide to the base speeds, these vary due to efficiency differences.


Number of Poles
2 Pole 3000rpm
4 Pole 1500rpm
6 Pole 1000rpm
8 Pole 750rpm

I need a Final Output Speed of...

If the Output speed you rquire from your motor doesnt match the ones in the chart above, dont worry. By using either an inverter, or a Motor Gearbox, we can give you a solution for almost any speed you may require. By adding a gearbox, you will also massvely increase the final torque output from your motor. See our Gearbox section for more details.

Common Questions


  • Can I run a 3 Phase motor from a Single Phase 230VAC Supply?
  • Yes. With the motor configured in a Delta set up and the correct Inverter, you can run motors up to 4kW from a Single Phase 230VAC supply. See the image to the right (below on mobile devices) to show Star or Delta setups.

  • How do I determine which mount or flange I require?
  • We have an infographic to help you to determine which mount you need. You can find it here. The basic types are Foot, Flange or Foot and Flange.

  • Can you fit Anti-Condensation Heaters to your motors?
  • Yes we can. This would be necessary if your motor is in an environment where it may be subject to atmospheric condensation.

  • Can I Speed Control a 3 Phase Motor?
  • Yes you can. Any of the Inverters in our AC range provide speed control, if you would like help in selecting one, please call us or use the contact us button below.

  • Do you have data sheets for the motors you sell?
  • Yes. Click on any of our motors and in the 'Downloads' section, you will find the relevant data sheets and dimensional drawings.
