Direct-drive motor with high-voltage option

By Control Engineering Staff November 1, 2001

Radford, Va. – Goldline DDR (Direct Drive Rotary) motors have a new high-voltage option allowing them to work with the company’s ServoStar 600 drive amplifier at 400 V or 480 V ac input. At these voltage levels, there is no need for a transformer in many applications. Resulting cost and space savings complement the direct-drive objective. DDR high-voltage motors offer two types of feedback-sine encoder or resolver, peak torque ratings up to 225 lb-ft, and speeds up to 500 rpm for driving direct-coupled loads with large inertia. IP67 sealing is an option.
