MPL-A4540F-SJ74AA

The MPL-A4540F-SJ74AA servo motor is an MPL series low-inertia rotary servo motor manufactured by Allen-Bradley. It is rated at 2.6 kilowatts, 3000 revolutions per minute, 240 Volts AC, 0.00052 kg-m2 rotor inertia, 18.4 Amps of continuous stall current, and 10.2 N-m of continuous stall torque. Its frame measures 130 millimeters, it can be mounted horizontally or vertically with the shaft facing up or down, and its magnetic stack length is 4 inches. The MPL-A4540F-SJ74AA servo motor features a 24 Volts DC holding brake to keep the shaft stationary when the servo motor is not in use. The holding brake doubles as a stopping brake in some situations but its frequent use as a stopping brake is not recommended.

A single-turn high-resolution encoder is the feedback option that comes with the MPL-A4540F-SJ74AA servo motor. The motor has circular DIN connectors that can be rotated 180 degrees, and the state-of-the-art winding technology used in the design of this servo motor makes its size significantly smaller than most servo motors with similar capabilities. In most applications, it is able to deliver up to 40% higher torque per unit size than traditional servo motors. The coils of the MPL-A4540F-SJ74AA servo motor are insulated with high-quality materials to provide efficient thermal management and prevent the overheating that might cause nuisance trips during operation. This servo motor is typically controlled by using drives from the Allen-Bradley Kinetix servo drive series. The MPL-A4540F-SJ74AA servo motor is capable of operating with a sustained shaft load. Also, it includes a mounting pilot for aligning the servo motor on the machine during installation.
