Engineered for Reliability and Serviceability

The 21-VLL series is designed with features that maximize reliability while

simplifying maintenance and operation. Application-specific thrust bearings

and optional non-reversing ratchets ensure upper bearing performance

under varying loads. A precision-built, split-core stator reduces core loss and

assembly time, while the copper bar rotor is optimized for pump applications

with enhanced starting torque and robust construction.

Modular cooling options—including water-to-air, air-to-air (IP55), and open air

circuits—support a wide range of operating environments with durable,

corrosion-resistant materials.

The TM21-TG Series generators are 2-pole, air-cooled generators.
