MAC112C-0-KD-0-C/130-A-1/S005 by Bosch Rexroth Indramat

The MAC112C-0-KD-0-C/130-A-1/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it converts command voltages from legacy controllers into precise mechanical motion for automated machinery, conveyors, and positioning tables, so paired amplifiers can regulate speed and position on older motion systems. Its design targets installations where high positional accuracy and dependable holding capability are required, especially on axes that must stop cleanly and remain stable at standstill during production.

This unit relies on passive cooling through natural convection, so enclosure airflow must remain unobstructed during continuous duty and no auxiliary fan is needed on the motor housing. It has a nominal speed of 1500 rpm, which suits common gear ratios used in material handling stations and similar machine layouts that favor steady mid-range speed. The stator housing has a 130 mm centering diameter that aligns the flange precisely with mounting frames and helps keep shaft runout within tolerance during operation. Integrated holding capability is provided by a blocking brake with 45 Nm of static torque, allowing the axis to stay parked when power is removed or when the machine must hold position between moves. The winding code KD indicates the phase resistance and inductance used with legacy analog drive amplifiers in the MAC platform.

The motor uses frame size 112 with length C, which gives moderate rotor inertia while still supporting high continuous torque density for repeated motion cycles without making the package excessively long. Power conductors exit through a connector on side A, simplifying cable routing inside cabinets that mount the motor with the shaft facing outward and reducing the need to cross wiring around the housing. Speed feedback is generated by a standard tacho generator that produces 3 V/1000 rpm, and its standard quality grade suits the velocity loop bandwidths typically used by analog servo regulators in established machine designs for stable speed feedback.
