Bearingless AC Generators Model 758 |
|||||||||
| Basic
These
are AC generators of the most basic form, consisting of only a stator and
a permanent magnet rotor wich mounts on a rotating shaft in the customer's
equipment. Designed primarily for use by OEM's, these extremely
rugged and dependable generators have no bearings or brushes and
therefore, require absolutely no maintenance. Because they are
impervious to oil, grease, and relatively high temperatures, they may be
installed in inaccessible areas, such as gear boxes, which permits the
saving of space and cost reduction. They have extremely low torque
burdens of less than one ounce-inch and are capable of speeds up to
100,000 rpm. Potted Models Units are available with the stator windings encapsulated with an epoxy material for greater protection. These are designed with the letter "P" in the type number. Mil-Spec Compliance. Model 758, types XPF86 and GF86 are designed to meet Mil-S-901 high shock as required by specification Mil-T-16049. |

| Rotor Installation The rotor of the generator unit should be mounted to the true center of the shaft with extreme care, particulary in higher speed applications. The relatively small inertia of the rotor makes it possible to secure it to the shaft with a right hand thread regardless of the direction of the rotation. It is recommended that a steel screw having an SAE thread be used to permit maximum tightening. NOTE: DO NOT press fit the rotor to the shaft, or the rotor will shatter because of the brittle nature of the magnetic rotor material. | |||||||||
| Indicators WestCon offers digital RPM indicators that operate from AC & DC voltage signals, and from AC frequency. These meters are specially modified to reduce the rapid fluctuation in display digits that result from varying speed rates. | |||||||||
