MPL-B580J-MJ74AA

The 3750 rpm-rated Allen-Bradley MPL-B580J-MJ74AA servo motor is a microprocessor-controller servo motor from the MPL series of low-inertia synchronous AC motors. It operates at an input voltage of 400 Volts AC and it delivers 7.9 kilowatts of output power. The motor comes with a standard IEC metric flange for mounting. Innovative winding technology on the MPL series servo motors like the MPL-B580J-MJ74AA servo motor provides up to 40% higher torque compared to traditional servo motors. Rare-earth magnets used in the servo motor’s construction lead to quicker acceleration. The smart motor technology includes onboard memory which retains the motor identity and the communications links report identity to the system upon startup, leading to reduced commissioning time.

The rotor inertia for the MPL-B580J-MJ74AA servo motor is 0.00289 kg-m2, and the continuous and peak stall current are 32 Amps and 115 Amps, respectively. The continuous and peak stall torque ratings are 34 N-m and 87 N-m, respectively. The servo motor frame size is 165 millimeters and its magnet stack length is 203.2 millimeters. The SpeedTec DIN connector on the servo motor allows flexible connector orientation (180 degrees rotatable) and it enables the use of a common cable family for all MPL series servo motors. The Hiperface protocol is supported by the 1024 sin/cos absolute multi-turn feedback encoder. Also included with the MPL-B580J-MJ74AA servo motor are a 24 Volts DC brake and a shaft key. The servo motor does not include a shaft seal. However, an optional shaft seal kit is available for achieving an IP 66 environmental protection rating. The shaft seal is a barrier that can protect motor bearings from the detrimental effects of dust and moisture. Shaft seals degrade with use and therefore periodic inspection and replacement of worn seals is recommended by Allen-Bradley.
