Rotary Drive - Installation Guide
Introduction
Product description
Welcome to the installation guide for the Raymarine rotary drive.
This product is intended to operate the boat's steering mechanism as
part of a Raymarine autopilot system. It 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
• an electromagnetic clutch that transmits high torque loads
