The Allen-Bradley/Rockwell Automation MPL-B420P-RJ72AA servo motor is a brushless servo motor. The servo motor has a rated operating voltage of 460 Volts AC. The MPL-B420P-RJ72AA servo motor uses a resolver module for feedback. The resolver module is used to measure the degrees of rotation. The motor has a speed rating of 5000 revolutions per minute and belongs to the Allen-Bradley/Rockwell Automation MPL series of brushless servo motors. The MPL-B420P-RJ72AA servo motors have a continuous stall torque rating of 4.74 N-m/42 pounds on an inch, a peak stall torque of 13.5 N-m/120 pounds on an inch, a rated power of 1.9 kilowatts, and an approximate weight of 4.3 kilograms.
Note that the Allen-Bradley MPL-B420P-RJ72AA servo motor system’s electromagnetic compatibility (EMC) can be enhanced by routing the cables correctly. When installing the cables, the cable lengths should be kept as short as possible. Additionally, the cables should be separated by 0.3 meters after every 9 meters of parallel run. Cables pertaining to I/O and other noise sensitive devices should be routed away from motor powering and input power cables. Note that a high voltage is likely to be present on the shield of the power cable. However, this is only likely if the power cable is not properly grounded or if it is not grounded at all. The Allen-Bradley MPL-B420P-RJ72AA servo motor, like other motors in the same series, produces leakage current in the protective earthing conductor that exceeds 3.5 milliAmps. The MPL-B420P-RJ72AA servo motor does not contain a brake. The motor’s bolt circle diameter is 115 millimeters and its magnetic stack length is 1.0 inches.
