Cooling System & Frame Optimised

The 90, 132 and 160kW motors and drives are being used in models from Atlas Copco’s ZS range of blowers, supplied for a range of demanding applications including wastewater treatment, food and beverage manufacture and chemical processing.

The WEG W22 three-phase motors have been designed specifically to meet the requirements of the most demanding industrial users, including reduced energy consumption, increased productivity, extended lifetime and lower maintenance. The frame and cooling system of the motor have been optimised to deliver better airflow to its internal components, for example, improving operating efficiency even in tough environmental conditions. Special bearing seals also extend the lifetime of the motor in aggressive environments by protecting it against the ingress of water and dust.
