Allen-Bradley N-Series Brushless Servo Motor Manual
IntroProduct Notice Use of Motors Servo motors are intended to drive machinery. As such, they must be part of a controlled system that includes a transistorized electronic amplifier. They are not intended for direct connection to the power supply or for use with thyristor drives. Instructions in the amplifier and control system manuals must be observed; this document does not replace those instructions.

Options: Connectors and Shaft Seals An environmentally sealed package may be formed when an N-Series motor is coupled with sealed cable assemblies and shaft seals. Factory manufactured power cables and encoder cables are available in standard cable lengths of 10, 25, 50, 75 and 100 feet (3, 7.6, 15, 23 and 30 meters). Factory cables provide environmental sealing and shield termination.
Motor Radial Load Force Ratings Motors are capable of carrying an axial load in most applications. The following table provides guidelines for 20,000 hour bearing life with a specified radial load applied to the center of the shaft. Please consult with Reliance Motion Control regarding loads, operating speeds and bearing life in your particular application to ensure the proper selection of motors.
Motor Installation Observe the following installation guidelines and those in the Product Notice: ! WARNING: Motors and linkages must be securely mounted for a system to be operational. Disassembled equipment should be appropriately identified (tagged-out) and access to electrical power restricted (locked-out). Failure to observe these safety procedures could result in personal injury and damage to equipment. 1. Do not run motors that are not properly mounted.
