Product Description:
The MAC112B-0-GD-2-C/130-A-1/S05 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive commands from legacy servo amplifiers into rotational motion for positioning tables, gantry axes, and similar industrial automation loads. Integrated speed feedback supplies speed information back to the controller so closed-loop regulation remains stable during rapid load changes. The motor is well suited to applications that require stable speed control during repeated starts, stops, and direction changes.
For holding duties when power is removed, the unit carries a standard blocking brake capable of supplying 45 Nm of static torque. Precise shaft alignment with adjoining mechanics is assisted by a 130 mm centering diameter, which sets the pilot fit between the motor flange and a machine plate. That pilot fit helps maintain concentric mounting between the motor and connected machine elements. Heat generated by copper losses is removed through natural convection, so no external blower or liquid circuit is required and surrounding airflow can remain simple. Velocity feedback is provided by tachogenerator feedback, enabling the analog drive to compare actual speed with the command signal in real time. The mechanical frame corresponds to size 112, giving the stator and rotor a diameter that balances torque density with manageable mass.
The motor has a length code of B, which helps confirm that adjacent equipment clears the rear housing. Power conductors exit through a connector on side A, keeping the cable bundle on the designated service side of the machine. This arrangement can simplify routing where the service side must remain accessible around the motor body. The motor uses winding code GD, so drive tuning parameters must match that impedance set for proper operation. Rear housing clearance and cable direction should be considered when the motor is installed near guards, plates, or other tightly spaced machine components.
