RDB-B29034-3B72AA

The RDB-B29034-3B72AA is a direct drive servo motor designed and manufactured by Rockwell Automation/Allen-Bradley. The motor has a bearingless housing. The RDB-B29034-3B72AA is designed to be used in direct drive applications due to its compact design. The motor has standard factory options but no brakes and its enclosure has an international protection rating of IP65. At an operating voltage of 440 Volts AC, the RDB-B29034-3B72AA has a base speed of 200 rpm. The frame’s size (bolt circle diameter) for the motor measure 290 millimeters. The Allen-Bradley RDB-B29034-3B72AA bearingless servo motor has 3 magnetic stacks and operates at a voltage class of 400 Volts AC. The feedback encoder for the RDB-B29034-3B72AA is a single-turn high-resolution Heidenhain while the connectors are circular DIN SpeedTec connectors at right angles.

The motor is prone to a shorter life than it is rated for after installation if maintenance is not regularly performed. To extend its life on the industrial floor, a drip loop to divert liquids away from the motor connections should be present and the motor should be checked for wear and damage on a regular basis. Additionally, the performance of the RDB-B29034-3B72AA can be greatly reduced by the presence of electrical noise. Therefore, to increase performance, the motor should be fed with input power after it has passed through a line filter. Additionally, the power cables, motor cabling, and signal cabling should be physically separated and a single-point parallel grounding system should be used for grounding. When installing the RDB-B29034-3B72AA, the hardened steel fasteners should be used to properly secure the motor in place. The RDB-B29034-3B72AA operates within a temperature range of 0 and 40 degrees Celsius. Note that the motor should not be installed in an enclosed environment unless cooling air is driven across the motor. The heatsink mass of the RDB-B29034-3B72AA should be sufficient to reduce the heat.
