Reduction of power consumption in motor-driven systems by using PM motors

On the basis of measurement on asynchronous motors and permanent magnet motors (PM motors) of various sizes and of ventilator and pump tests, the project calculated the savings potential of replacing existing motors by the more energy-efficient PM motors in the industry. The potential was determined at 556 GWh/year, equal to 8%. Furthermore, with other system optimisation initiatives (ventilators, pumps, transmission components and energy-efficient control and adjustment), similar savings can be achieved, equal to a total of about 16% of electricity consumption for motor operation.
