Electric motors cut losses by 40%

Said to be quieter, more reliable, easier to maintain and more cost effective than competing models, the three-phase induction motors are the only ones on the market which exceed IE4 regulations, enabling manufacturers to increase energy efficiencies throughout their plants and processes, and reduce their total cost of ownership. Suitable for industrial applications including fans, blowers, pumps and compressors, they are specified to work across the full power range from 3 to 355kW and optimised to offer up to 40% less losses compared to previous designs. The motors have been designed to have low operating temperatures, which WEG says increases the insulation time and results in a long service life. The frame and cooling system of the motor has been optimised to deliver 'exceptional' airflow to its components, improving operating efficiency even in tough environmental conditions. According to the company, it delivers increased lubrication intervals and therefore needs minimal maintenance and servicing. High performance rubber drains allow for easy motor drainage during servicing, and provide high protection at harsh conditions. Special bearing seals also extend the lifetime of the motor in aggressive environments by protecting it against the ingress of water and dust.
