LINEAR DRIVE UNIT
The output ram of the linear drive unit is driven by
a declutchable recirculating ball leadscrew which
enables the drive unit to be permanently coupled
to the rudder stock via a simple crank or tiller arm.
The drive is automatically engaged by means of
an internal friction clutch when the autopilot is
switched to ‘Auto’ and will disengage instantly
even under heavy load when the autopilot is
switched to ‘Stand-by’. The motor is controlled by
the course computer which regulates peak
current and eliminates the need for end limit
switches.
