Section 6: GYRO SPECIFICATIONS
Arrangement
The Model 8000 Gyro System consists of the Gyro unit, Motor Drive Box, Gyro Control Box, Cooling Loop
Components, Display, and Cables (for cables not supplied by Seakeeper, refer to Seakeeper Drawing
90149).
Installation Location
The Gyro is a torque device and does not have to be installed in a specific hull location or on the
centerline. However, the Gyro should not be installed forward of the longitudinal center of gravity in a
planing vessel where the vertical accelerations exceed ±1 G.
Mounting Dimensions
See Seakeeper Installation Details Drawing 90123.
Loads
The installer is responsible for designing the foundation to which the Gyro’s saddle beams are attached
and for ensuring that this foundation can safely transfer the concentrated Gyro loads from the saddle
beams to the adjacent hull structure. Loads that the Gyro imposes on the saddle beams are explained
on page 6 of Seakeeper Drawing 90123.
Cooling
The Gyro bearings, Motor Drive Box, and hydraulic manifold are cooled by a closed water / glycol mix
cooling loop that incorporates a sea water heat exchanger. The installer is responsible for providing 15
LPM (4 GPM) minimum and 30 LPM (8 GPM) maximum raw water at ambient sea temperature and 1.4
Bar (20 psi) maximum sea water pressure to the heat exchanger. The ambient air temperature in the
compartment in which the Motor Drive Box is mounted should not exceed 60
o
C.
Electrical
The installer is responsible for supplying 208 ‐ 230 VAC, 50/60 Hz, single phase power on a 20A service to
the Motor Drive Box and 24 VDC @ 10A service to the Gyro Control Box. Separate circuit breakers
should be used for each Motor Drive Box in multiple gyro installations. Similarly, separate circuit
breakers should be used for each Gyro Control Box in multiple gyro installations.
