Product Description:

The MAC112D-0-FD-3-C/180-A-1/S003 is a servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit is intended for analog drives that require closed-loop torque and velocity regulation in production lines, material-handling gantries, and other industrial axes. Integrated tachometer feedback supplies a proportional voltage to the drive, allowing the control loop to correct speed changes under varying load. A standard blocking brake holds position when the system is de-energized, and a second shaft end provides a convenient point for external encoders or auxiliary mechanical couplings in multi-drive assemblies.

A centering diameter of 180 mm aligns the housing precisely with machine mounting faces, helping reduce radial misalignment during installation. The nominal speed of 2000 rpm allows the drive amplifier to support continuous motion in medium-inertia loads without overspeeding the rotor. Heat is removed by natural convection, so the motor relies on surrounding airflow rather than forced cooling hardware. During deceleration or vertical holding, the integrated brake can resist up to 45 Nm, limiting shaft movement when power is lost. For velocity feedback, the internal tacho generator produces 3 V/1000 rpm, giving the analog controller a linear signal for closed-loop regulation.

The winding designation FD identifies the stator wire gauge and turns per phase, so the motor can be matched with compatible analog amplifiers and expected current behavior. Frame designation 112 indicates the overall flange size and sets the mechanical interface height relative to adjacent axes. Axial length code D extends the active core to support higher continuous torque than shorter versions in the same frame. Electrical power is routed through a connector on side A, which keeps service access clear on the opposite face and simplifies harness routing in narrow cabinets.
