Ian Allan, ABB's UK Business Unit Manager for Motors and Generators, writes: Alongside purchase price and the cost of running an electric motor, there are also the costs associated when a motor is not running. This is the direct cost to a continuous process industry of lost production due to a motor failure. Such costs vary widely, depending on the industry.

So, the cost of ownership is the purchase price and installation costs, plus the cost of running, plus the cost of not running.

For example, a 45 kW motor costing £1,738, with 94.1 percent efficiency and running for 6,000 hours per annum could cost around £600,000 over a 20 year life. This assumes an average electricity price of £0.09 and the downtime cost of every five years of say £20,000.

As we can see, true cost of owning a motor is far more important than the initial purchase price. Which is more expensive to own: an electric motor that costs £790, or one with a price tag of £1,185?

The IE3 regulations are your chance to ask your motor vendor what they provide to help you cut these costs down to size. High reliability?  A service plan?

Clearly, a low purchase price doesn’t tell the whole story and you need to ensure you are buying a lifetime of low costs, not a one-off cheap deal.
