Product Description:

The MAC112D-2-FD-1-B/130-A-0/J1250/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it supplies closed-loop torque and speed control to machine tools, printing lines, and other automated stations. It works with an external amplifier so commanded current can be translated into controlled shaft motion during acceleration, deceleration, and steady operation. Its operating concept suits applications that rely on precise rotary positioning and stable speed regulation during repeated motion cycles.

This unit relies on axial surface cooling assisted by an internal blower that runs on AC 115 V. These features keep the stator temperature within permissible limits at continuous load. A centering flange diameter of 130 mm aligns the housing to the driven machine without additional shims, while the rotor is optimized for a nominal speed of 2000 min⁻¹ to match standard analog velocity loops. Winding code FD indicates the resistance, inductance, and thermal characteristics of the motor. The D motor length provides the active stack height associated with this torque class, and the construction omits a blocking brake, so an external locking device must hold the shaft when power is removed.

Closed-loop feedback is delivered through incremental encoder signals, and a drive-mounted tacho generator rated at 3 V/1000 min⁻¹ supports speed monitoring. This feedback arrangement allows the control loop to track both speed behavior and position changes during motion. Power conductors exit through a connector on side A, which can simplify cabinet cable routing on right-hand installations. The motor size code 112 indicates the stator diameter used for this frame and helps match the motor to compatible couplings and gearboxes.
