Installation and Operation Manual 1329R Small AC Motors • 1/3 through 3 HP • 56-W180T
1329R Small AC Motors Installation and Operation Unpacking Unpack motor carefully and inspect for possible damage during shipment. Check packing materials and save any instruction tags or wiring diagrams found in the carton. Report any damages or shortages immediately to the local transportation agent. Before connecting motor to the electrical supply, inspect for any damage resulting from shipment. Turn shaft by hand to assure free rotation.
1329R Small AC Motors 3 Since 15/16” is not a standard bolt length, a 7/8” bolt or a 1” bolt with a lockwasher can be used. ! ATTENTION: To guard against motor damage such as premature failure and/or a loose assembly, use only mounting bolts that are the correct length. A bolt that is too long may cause damage to the motor. Wiring Check nameplate data on motor before installing to assure correct rating and that the available power supply agrees with the motor power supply.
1329R Small AC Motors Blower Motor Connection Vector Duty W180T frame motors may incorporate the use of a blower motor for cooling. In these cases a single-phase, 115V, 60 Hz blower motor is used.
1329R Small AC Motors 5 Maintenance ! ATTENTION: High Voltage. Electric shock may cause serious or fatal injury. Disconnect power before touching any internal part. The fundamental principle of electrical maintenance is – Keep The Apparatus Clean And Dry. This requires periodic inspection of the motor, the frequency depending upon the type of motor and service. The following should be checked at regular intervals. 1. Windings should be dry and free of dust, grease, oil, and dirt.
1329R Small AC Motors Sleeve Bearings The bearing sleeve is steel on the outside for strength with a tin base babbit lining on the inside for low friction and long wear. A storage space around the bearing is filled with Permawick, a commercial composition of special cellulose fiber highly saturated with oil. The initial factory Iubrication is normally adequate for approximately one year under normal operation. Thereafter, lubricate about every six (6) months.
1329R Small AC Motors 7 6. That the line voltage, frequency and phase correspond to the values stamped on the nameplate. 7. That all connections and contacts are properly made in all circuits between motor and line, and between motor and control. Warranty Allen-Bradley warrants workmanship and materials on each Fractional Horsepower AC Motor for one year from date of shipment. This warranty does not extend to failures induced by misuse, abuse or misapplication.
1329R Small AC Motors Removing and Replacing Ball Bearings Should it become necessary to replace bearings, the bearing bore and cavity should be thoroughly cleaned and repacked with approximately 1/2 teaspoonful of recommended grease (Chevron SRI #2 or equivalent). Bearings should be removed with bearing pullers using a center insert in the end of the shaft to protect the shaft center. If a puller is not available, use a fiber hammer and transmit blows through a hard wood block.
