Product Description:

The MAC112D-0-ED-1-B/130-A-0/J1250/S05 servo motor is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, this motor delivers closed-loop positioning and velocity control for transfer lines, machine tool axes, and automated handling modules. By converting regulated three-phase power into mechanical torque, it supplies the controlled rotary motion required for synchronized multi-axis tasks across industrial automation platforms. Its mechanical interface and electrical ratings allow direct integration with legacy transducer cards and analog velocity loops. This makes the motor suitable for equipment that relies on stable speed response and repeatable positioning during continuous production cycles.

Nominal shaft speed reaches 3000 rpm, providing the dynamic range needed for rapid indexing without exceeding bearing limits. Heat produced during operation leaves the frame through natural convection, so no external blower or liquid circuit is required. Rotor position is monitored by incremental encoder feedback, allowing the analog drive to generate proportional current for tight velocity regulation. A 130 mm centering diameter aligns the flange with precision gearboxes and helps maintain concentricity under load. For velocity verification, the built-in tacho generator outputs 3 V/1000 rpm, letting legacy controllers compare measured speed against the command signal in real time.

The motor has a length D, which provides the stack height needed for the rated torque while still fitting within common cabinet depths. The 112 frame size standardizes mounting threads and shaft diameter across the MAC range. Power conductors enter through a connector on side A, keeping cable bends consistent with earlier installations and leaving the opposite face free for feedback wiring. The motor uses winding code ED, so a matching drive module can be selected for the proper electrical characteristics. The unit ships without a blocking brake, so the load must coast or be held by external mechanics when power is removed.
