Pacemaster 2

The Pacemaster 2 series from Cleveland Machine Controls is a family of DC motor controls built to regulate the speed and torque of DC motors in industrial applications. These SCR-based drives handle armature and field circuits and are commonly found in paper handling, material handling, and general industrial machinery.

The series includes drives rated for 3 to 5 horsepower DC motors, offered in multiple enclosure configurations such as open chassis and NEMA 4 versions, along with standalone control boards. Configurations use a bridge rectifier arrangement with adjustable horsepower settings, and typically operate on single-phase AC input to provide adjustable DC output.

Common Variants

• Enclosed and open-chassis drives — 3 to 5 HP DC motor controls for standard and NEMA 4 environments
• Control boards — board-only replacements for existing installations
• PM2C and PM2E controls — configurations providing adjustable DC output with relay logic for armature contactor control
