UNITROL excitation systems for motors

Automatic start and smooth operation for synchronous motors

UNITROL

6080 - Proven flexible solutionsUNITROL 6000 is ABBs latest generation of indirect (AVR)

and static excitation systems (SES). Its smaller version,

UNITROL 6080, is a compact and cost-effective solution with

full functionality. It offers high performance control, easy op-

eration, monitoring and maintenance of the system. Limiting

and protecting functions keep the system within safe range

and increase the reliability.

Synchronous motors are used in many industries for

driving pumps, fans, mills and other large loads.

No matter the application, UNITROL automatic voltage

regulators ensure optimal and safe operation of the motor

at all times. Operator commands can be reduced to start

and stop with the integrated sequence control.

UNITROL excitation systems can be fitted to any motor

brand.
