Product Description:

The MAC112C-0-ED-3-C/130-A-1/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built for analog drive systems, the unit transforms ±10 V speed or torque commands into controlled rotary motion for industrial automation axes. It provides the link between drive electronics and machinery, delivering responsive acceleration, deceleration, and steady operation for indexing tables, gantry carriages, and spindle loaders that must maintain repeatable positioning under variable payloads. The motor is intended for applications that rely on external drive regulation rather than integrated digital control.

Its integral blocking brake produces 45 Nm of torque, holding the shaft immobile during power loss or emergency stops. When energized, the rotor reaches 3000 rpm, giving moderate surface speed for synchronous coupling with standard gear stages. A centering shoulder of 130 mm locates the flange concentrically, which helps reduce misalignment and vibration. Thermal energy exits the housing through natural convection, so no external fan wiring is required. Speed feedback is generated by a tachogenerator that outputs 3 V/1000 rpm, allowing the analog controller to scale loop gains directly from the voltage signal.

The electrical characteristics are tailored for compatibility with legacy amplifiers. Winding code ED identifies the copper turns and impedance used for rated current without excessive phase lag. The frame length code C increases the active magnetic stack, raising continuous torque while retaining a manageable moment of inertia. Housing size 112 matches MAC mounting accessories used with this frame. Power enters through a connector on side A, keeping cable bends within the motor envelope. Tacho feedback is provided on the second shaft end, and the motor uses standard tacho quality.
