Introducing the VLL Series: High-Capacity Vertical Motors

The 21-VLL series three-phase medium-voltage motors are designed

for large capacity applications.

• UP to 6500 kW (8.700 HP)

• WPII, TEAAC and TEWAC and custom frames

• Designed to meet worldwide standards

• Fabricated steel plate construction

• C5 steel lamination

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.
