Product Description:

The MAC112D-2-D-2-B/130-A-0/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it delivers commanded torque and speed to axes that rely on voltage or current reference signals from a separate drive amplifier. The design targets production machinery that needs responsive motion control during frequent starts, stops, and speed changes, and its housing accepts an external blower so the active parts can be cooled without enlarging the stator frame. This layout helps the motor fit crowded machine bases where installation space is limited.

Axial heat removal is handled by axial surface cooling, and the main enclosure meets IP65 so dust and water jets do not reach the windings. Power enters on side A, which simplifies cable routing where drives sit to the right of the actuator. The centering shoulder is 130 mm, while the rotor shaft is 32 mm in diameter for couplings or pulleys. Frame coding identifies motor size 112 and length D, which indicate the body size and stack length used for this housing. Position feedback comes from tacho feedback, which produces an analog velocity signal that analog controllers use for closed-loop regulation under changing load conditions.

The external blower runs at AC 115 V, and its motor casing carries IP44 while the attached shroud is rated IP24, a combination that protects against workshop splash and keeps airflow moving across the stator ribs. For secure fixing, the flange provides 4 x M10 x 15 threaded holes that accept standard metric bolts. This mounting hardware maintains alignment up to the service altitude limit of 1000 m, where cooling air density still supports the axial fan. The mounting pattern suits legacy analog drive lines that still use external blower cooling and conventional flange-mounted motor layouts.
