The Rotary drive is designed for steering systems that can be driven from the helm position through a chain and sprocket (for example: cable and rod steering systems).

The outstanding design of the Raymarine rotary drive unit provides smooth, powerful autopilot-controlled steering with quiet operation.

The main parts of the drive are:

• a rugged electric motor, that drives a precision epicyclic gearbox via a high tensile drive belt

• an electromagnetic clutch that transmits high torque loads without slipping
