MAC112D-0-ED-1-B/130-A-0/-I01250/S05

The MAC112D-0-ED-1-B/130-A-0/-I01250/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for closed-loop motion axes in packaging, printing, and general automation, the unit converts drive current into rotational power that can be governed by analogue controllers and encoder feedback. Its construction matches the mechanical interface and electrical ratings standardized across the series, allowing quick exchange and straightforward commissioning in multi-axis systems.

Mechanical alignment is set by a centering diameter of 130 mm, which seats the flange precisely on gearboxes or mounting frames and minimizes radial runout. Heat produced by the stator windings is removed through natural convection, so no external blower or liquid circuit is required; this influences cabinet layout and ambient temperature limits. Servo position and velocity are reported with incremental encoder feedback, enabling analogue drives to close speed and position loops with fine resolution. At a nominal shaft speed of 3000 min⁻¹, the motor delivers rated torque while staying within thermal limits typical for its frame. The electromagnetic design identified by winding code ED defines phase resistance and inductance so that the connected amplifier can apply correct current profiles.

The motor frame is classified as size 112, and its axial length is the D variant, giving a balance between torque density and inertia for mid-range loads. Because a blocking brake is not present, the shaft must be held by the drive or external mechanics during power-off conditions. Power conductors exit through a connector located on side A, simplifying cable routing in cabinets where multiple axes sit in parallel. For analog speed loops that rely on tachogenerator feedback, the built-in tacho produces 3 V/1000 min⁻¹, providing a proportional voltage signal that the controller can use for real-time velocity regulation.
