Electric motor–driven systems consume large amounts of electrical energy and can provide an opportunity for significant energy savings. Energy represents more than 97% of total motor operating & maintenance costs over the motor’s lifetime. However the purchase of a new motor or the maintenance of an existing motor often tends to be driven by price or performance, not the electricity it will or is consuming. Even a small improvement in efficiency could result in significant energy and cost savings while also reducing the greenhouse gases that contribute to climate change.

The table below compares the capital cost of various motor sizes with their running costs by showing approximately how long it takes to consume their own capital cost in energy cost,

A motor, irrespective of its rating, will consume its purchase price in energy costs during its first month of continuous operation
