Product Description:

The MAC112D-0-HD-3-C/130-A-2/S018 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as the electromechanical actuator for analog drive controllers, delivering closed-loop motion in presses, packaging stations, and gantry axes. The unit occupies the 112 frame code with a D-length housing, supplying a mechanical envelope suitable for mid-range torque tasks.

A centering pilot of 130 mm aligns the flange with the driven load and maintains concentricity during acceleration. Internal heat is removed through natural convection, so unobstructed airflow around the housing is required instead of forced-air or liquid circuits. The rated shaft speed is 1500 rpm, matching common 50 Hz drive frequencies and providing predictable velocity constants for gearbox selection. Three-phase power reaches the stator via a molded plug oriented toward side A, which helps cable routing when the motor is mounted inside tight enclosures. During fast decelerations, the brake can resist up to 60 Nm of static load, preventing drift until drive torque resumes.

The motor includes a heavy-duty blocking brake that engages mechanically when power is removed, holding vertical loads with the torque capacity noted above. Rotor motion feedback is provided by a tachogenerator; the build note with tacho feedback and a second shaft end means the tachometer is mounted internally while an auxiliary shaft stub is available for an external encoder or belt drive. The generator delivers 3 V/1000 rpm, giving the analog drive a proportional speed signal without digital conversion. Classified as a motor for analog drives, the model pairs with classic INDRA analog amplifiers where current setpoints are voltage-driven. The winding designation HD marks a low-resistance, high-current stator that favors dynamic torque rise over extended duty cycles.
