Description

VEM K21R 280 M4 WS 3-Phase Induction Motor - 1997

The VEM K21R 280 M4 WS is a high-performance 3-phase asynchronous (induction) motor manufactured by VEM motors GmbH in Germany, designed for rugged industrial operations with continuous (S1) duty. Featuring a horizontal foot-mounted (IM B3) design, this motor is built with a ribbed cast iron housing and an external fan for efficient TEFC (Totally Enclosed Fan-Cooled) heat dissipation, suitable for dusty or humid environments.

With a frame size of 280, the motor's precision-balanced rotor and laminated high-efficiency core ensure smooth operation and minimal vibration. It conforms to DIN EN 60034 / IEC 60034 standards and comes with IP55 enclosure protection, making it resistant to dust ingress and water jets. The motor is equipped with C3-grade ball bearings (6317 C3) on both drive and non-drive ends, extending bearing life in high-demand environments.

Ideal for long-term, maintenance-friendly installation, the K21R 280 M4 WS is suitable for various heavy-duty industrial machines requiring reliable, high-output motors.
