DC Motor Controls
Introl Design, Inc.

Introl Design, Inc. has been designing and manufacturing SCR drives for DC motors since 1970. Introl Design’s product line ranges from 1/8 hp single phase to 50 hp three phase drives, and includes regenerative and unidirectional drives for shunt and permanent magnet motors.

Some drives found in our product line are analog, while others are microprocessor based, allowing excellent response characteristics. The three phase drives are full wave, which improves efficiency and form factor, resulting in cooler operation.
