Model 4000 Motor Controller

The Model 4000 Motor Controller series is a family of DC motor speed controls manufactured by Eaton Dynamatic. These products provide regulation of motor speed and, on units equipped with the appropriate option card, torque control for industrial drive applications.

The series is built around a common Model 4000 base control, identified primarily by the 15-533, 15-535, and 15-536 part-number families. It includes standalone control boards, complete controllers, and assemblies fitted with add-on options such as the torque option card. Many variants share the underlying control board design, distinguished by their specific configuration and option content.

Products in this series are commonly applied in paper processing equipment and similar industrial machinery where precise motor speed regulation is required.
