6.1.1 Intended use. The motor is to be used to actuate the control sur-
faces in an automatically controlled steering system.
6.1.2 Description. The motor is a direct current type with integral
gear reduction.
6.1.3 Storage life. The motor when packaged and preserved for overseas
shipment shall be capable of meeting all requirements after a minimum pe-
riod of 5 years.
6.1.4 Installed life. The motor, in the ready, nonoperating condition,
shall be capable of meeting all requirements after a minimum period of
1 year.
6.1.5 Design considerations. While stall torque is not a requirement
of this specification, it is a useful design parameter which may be em-
ployed, with no-load speed, to summarize the speed/torque capabilities
of the motor. Assuming a linear relationship of speed and torque, the
stall torque obtained by extrapolation horn speed versus load data (4.7.-
3.5) is intended to be at least 600 oz-in.
6.2 Ordering data.
Procurement documents should specify the following:
(a) Title, number, and date of this specification.
(b)
Required
level
of
preservation
and
packaging.
(c)
Required
level
of
packing.
(d) Assigned activity for preproduction and periodic tests.
(e) Required data.
(f) Any exceptions to this specification.
(g) All additional samples required shall be provided and inspec-
ted at the expense of the supplier, when such additional samples are re-
quired because of failure of any sample(s) to pass the prescribed inspec-
tions.
6.3 Definitions. For the purpose of this specification, the following
definitions apply:
6.3.1 Vibration. Vibration is a sinusiodal motion defined by amplitude
and frequency.
The amplitude may refer to displacement or acceleration.
The displacement is given in inches peak-to-peak or the corresponding
maximum acceleration in gravity units (g). The frequency iS given in
Hertz (Hz).
