Product Description:

The MAC112B-0-GD-2-C/130-B-0/S005 is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is classified as a motor for analog drives, meaning its velocity and torque are regulated by analog command voltages rather than fieldbus messages. In industrial automation, this unit provides tightly controlled rotary motion for tasks such as positioning, traversing, or spindle rotation where predictable response and repeatable accuracy are required.

The mechanical frame of the motor is designated by size 112, a code that indicates its flange dimensions and shaft height for compatibility with standard gearboxes and mounts. Its active magnetic stack corresponds to length code B, which supports the continuous torque capacity available from the stator. Electrical behavior is tied to winding code GD; this selection sets the phase resistance and inductance so the drive can deliver rated current without magnetic saturation. Accurate coupling to adjoining machinery is aided by a centering diameter of 130 mm, which positions the housing concentrically in a pilot bore to minimize runout. Heat generated in the windings is removed by Natural convection, so no external blower or liquid circuit is necessary.

For holding duties during power loss, the motor has no blocking brake, so any load-side locking must be handled by external mechanisms or continuous drive torque. The three-phase power leads exit through a connector on side B, which can simplify cabinet layout when the motor rear faces the cable track. Speed feedback is supplied by a tachogenerator with standard accuracy, and the configuration includes tacho feedback; this analog voltage signal allows the controller to close the velocity loop without a digital encoder and maintain consistent speed under varying loads.
