Page 2: Receiving And Handling
Small DC Motors Receiving and Handling ATTENTION: Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should install, adjust, operate, and/or service this motor. Read and understand this manual in its entirety before proceeding. - Page 3 Small DC Motors When mounting through a flexible coupling, verify that there is adequate clearance between the driven equipment shaft, the coupling interface and the motor shaft. Lack of clearance may result in binding of the shafting and premature bearing failure. Always slide the motor tenon into the mating flange to its full depth before tightening the mounting bolts.

Page 5: Maintenance
In the event of motor failure due to an over temperature condition, Rockwell Automation requires that motor thermal protective devices (when supplied) be adequately monitored and incorporated into the motor control system to maintain warranty. - Page 6 Small DC Motors Bearings Ball bearings are deep grooved, double shielded with sufficient lubricant packed into the bearings by the manufacturer for “life lubrication.” The initial lubricant is supplemented by a supply packed into larger reservoirs in the end shield at time of assembly. No grease fittings are provided. The initial lubrication is adequate for up to 5 years of operation under normal conditions.

Small DC Motors General ATTENTION: Internal parts of this motor may be at line voltage even when motor is not rotating. Disconnect all AC line connections before contacting any internal part. The following should be checked at regular intervals: • Windings should be dry and free of dust, grease, oil, and dirt. Windings may be cleaned by suction cleaners or by wiping. - Page 8 The latest motor information can be obtained from the Allen-Bradley Drives & Motors home page on the World Wide Web at: http://www.controlmatched.com 1325R-UM001B-EN-P Ð August, 2001 Publication Supersedes 1325R-UM001A-EN-P dated May, 2001 Copyright © 2001 Rockwell Automation.
