Motors and drives 

Running motors and drives uses almost two thirds of the electricity consumed by UK industry. In fact the cost of running a motor for a year can be ten times what it cost to buy in the first place. The efficiency of your motor operation is therefore of critical importance to the lowering of your carbon footprint and reduction of your energy bills.

The motors and drives technology overview (PDF) gives an introduction to the main energy saving opportunities for businesses.

This section offers indispensable advice for making your motors and drives more efficient, from simple housekeeping tips to detailed advice on upgrading equipment and systems.

Introduction

 

The motors and drives technology overview (PDF) introduces some basic energy saving opportunities for businesses using motors and drives, and demonstrates how simple actions save energy, cut costs and increase profit margins. For more practical motors and drives energy-saving guidance why not listen to our training webinar delivered by industry expert, Charles Gaisford?

Top 2 recommended carbon saving measures for motors and drives:

1. Select higher efficiency motors


Specifying higher efficiency motors for new and replacement applications will save money, the small additional price premium usually paying for itself in less than two years. For higher duty motors, look out for best in class efficiency motors (at least IE3).

2. Install variable speed drives


If the load being driven by your motor has a varying demand then a variable speed drive could save energy. A small speed reduction can lead to substantial reductions in energy use. The most common applications are to control flow rates in fan or pump systems, as an alternative to using dampers or valves. See the difference a variable speed drive makes, in this short video of a typical installation.
