High Speed: Totally Enclosed Air Cooled and Non-Ventilated Motors

PRODUCT FAMILIES

HIGH SPEED: TOTALLY ENCLOSED AIR COOLED AND NON-VENTILATED MOTORS

Reuland's Totally Enclosed Fan Cooled motors (TEFC) are typically offered with a shaft-mounted fan for efficient cooling. An auxiliary blower is used in place of a shaft-mounted fan for motors (A-TEFC) operating at very low or very high speeds or to achieve a higher power performance. For applications, where the use of a shaft-mounted fan or an auxiliary blower is not practical, Reuland offers a line of Totally Enclosed Non-Ventilated motors (TENV).
