Product Description:

The MAC112D-0-FD-1-B/130-B-2/I1000/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it interfaces with voltage-command drive amplifiers to provide accurate torque and velocity control. The 112 frame and D-length stack supply the power density needed for medium-duty industrial axes, while the mechanical design allows direct coupling to gearboxes or belt transmissions used in automated assembly, printing, and material-handling equipment.

The motor’s blocking brake exerts 60 Nm of static torque, preventing load drift on suspended or vertical mechanisms when power is removed. A 130 mm centering diameter aligns the flange to machine bases and supports concentric mounting. Thermal energy leaves the housing through natural convection, so placement must allow unobstructed air circulation to maintain acceptable winding temperature. Rotor position is monitored by incremental encoder feedback, which outputs quadrature pulses for real-time velocity loops and position latching. During steady operation, the shaft speed stabilizes at 2000 rpm, corresponding to the nominal operating point for the FD winding and supporting synchronous interaction with standard 50/60 Hz driven processes.

The power conductors exit through a connector on side B, enabling cable routing along the non-drive end and keeping service loops away from moving tooling. For velocity verification in analog control circuits, the built-in tacho generator produces 3 V/1000 rpm, supplying a proportional voltage that the amplifier can compare with the command signal. The FD winding code indicates the stator resistance and inductance set, giving the drive fixed electrical values for tuning current loops without an additional winding lookup.
