MPL-B640F-MJ74AA

The MPL-B640F-MJ74AA servo motor is an AC motor from Allen-Bradley. This servo motor requires a reinforced timing belt or a torsionally rigid coupling when it is making mechanical connections. All connections between the system and the servo motor shaft must be rigid to achieve acceptable responses from the system. To ensure that the rigidity is maintained at all times, periodic inspection of the connections is recommended. Additionally, rigidity can be ensured by properly aligning the couplings and pulleys to the motor’s shaft and observing that axial and radial loads are within the proper specifications for the servo motor. The Allen-Bradley MPL-B640F-MJ74AA servo motor has a voltage rating of 400 Volts AC and an operating relative humidity between 5 and 95% without condensation. The servo motor is part of the Allen-Bradley MPL series of low-inertia servo motors.

The MPL-B640F-MJ74AA servo motor employs a multi-turn high-resolution encoder for feedback. Note that damage to the feedback encoder can be caused by applying leverage from the servo motor mounting face to remove devices mounted on the motor shaft. The MPL-B640F-MJ74AA servo motor, like other motors in the same family, is designed to be mounted and installed by a qualified technician to avoid damage to other equipment on the industrial floor and injuries to the users. The MPL-B640F-MJ74AA servo motor contains circular SpeedTec DIN connectors that are rotatable within 180 degrees. However, the connectors should only be rotated once during the initial cable connecting process and then kept in that position. The motor has a 24 Volts DC brake, standard factory control options, and an IEC metric mounting flange with free mounting holes. The MPL-B640F-MJ74AA servo motor does not feature a shaft seal.
