. Development of an underwater manipulator for use on a free-swimming unmanned submersible. Manipulators (Mechanism); Oceanographic submersibles. HANDLING. STORAGE, INSTALLATION Greater care is required for handling frameless dc torque motors than for housed units or conventional ac motors. The armature, field, and brush assembly are supplied as a matched set identified serially and should not be interchanged with other components. They are packaged separately in the shipping container. During unpacking and handling, and throughout installation, care must be taken to avoid bending or distorting the brush assembly springs, and to protect the commutator surfaces from scratching or contamination by oil or fingerprints. The field is supplied with a "keeper" ring, attached by magnetic force, which must not be removed until the field is installed and the armature is in place. To do so will result in approximately 1/3 reduction in torque sensitivity. Frameless units should be stored in nonmagnetic racks or containers — the shipping container is suitable — to prevent interaction of magnetic fields. Attraction of magnetic particles also should be avoided. Protect the armature core from moisture with desiccant. 14. Using the motor armature (with the rotor spacer in place), push the keeper out of the motor field. ATTENTION: Removing the keeper with- out substituting it with the field; - or placing the field on steel shelves or benches, unless separated from the steel by at least one-half inch of non- magnetic material; - or letting the field come in contact with the ferrous tools or measuring instruments will demagnetize the field up to 50%.. COMPONENT PARTS - DEFINITIONS Armature. The rotating element. The wind- ings are in this part. Commutator. A conductive segmented ring on the armature, which allows electrical power to be transferred to the winding from the stationary element. Field. The stationary permanent magnet assembly that produces the magnetic flux fi
