VARIABLE SPEED DRIVES

We have over 20 years experience in Industrial Automation, Electrical Engineering and Variable Frequency Drives, our engineers are experts on ABB Drives, Danfoss, Emerson Control Techniques as well as all other manufacturers

Installation, Commissioning & Repair

We can provide on site installation commissioning and repair of all major drive types, our engineers will install your Variable Speed Drives following the latest electrical regulations and technical standards. We will commission your drive to match your application requirements, ensuring parameter settings are set up correctly to your needs. 

Drive repairs can be done on site or off site and all issues will be fully diagnosed and repaired. We hold stock of spares for ABB Drives as well as other manufacturers. Once your drive is fully restored, we can come back to site and re-install and commission for you. 

What is a Variable Speed Drive?

A Variable Speed Drive (VSD), in general is a device either mechanical, hydraulic or electrical that will vary the speed of driven equipment. A sub-category also known as a Variable Frequency Drive (VFD), is an electronic controller that adjusts the speed, torque, and direction of an electric motor by varying the input frequency and voltage.

In simple terms — it lets your motor work only as hard as it needs to, saving energy and reducing wear.

Common uses include:

  • Controlling pumps, fans, conveyors, and compressors
  • Reducing start-up current (no more electrical spikes)
  • Matching motor speed to demand for smoother processes

Benefits of Using VSDs

Energy Savings

Motors consume only the energy required for the task, reducing power use by up to 50%.

Precision Control

Fine-tune your motor performance for smoother acceleration, constant speed, and soft stopping.

Reduced Wear & Maintenance

Lower mechanical stress means fewer breakdowns and longer life for both the drive and motor.

Lower Operating Costs

Save on electricity and maintenance — and extend the lifespan of your equipment.

Versatility

A single VSD can serve multiple applications — from simple fans to complex automation systems.
