Product Description:

The MAC112D-1-ED-2-C/130-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it converts ±10 V velocity or torque references into controlled shaft rotation for industrial automation systems. The unit is intended for applications such as carton erectors, feeder lines, and gantry axes where reliable speed regulation is required without a digital fieldbus interface. Its construction supports rapid acceleration, continuous-duty service, and straightforward integration into cabinets that already house analog amplifiers.

The mechanical interface uses a centering pilot of 130 mm, allowing precise concentric mounting to gearboxes or machine frames and minimizing radial runout. At a nominal speed of 3000 rpm, the rotor delivers rated torque while staying within the thermal limits of the motor’s D-length housing. Heat is removed through axial surface cooling. The stator fins are cooled by an auxiliary blower that runs on AC 230 V, and this forced airflow maintains winding temperature during high-duty cycles. A built-in tachogenerator supplies analog velocity feedback, and its response accuracy is classified as standard tacho quality, providing predictable loop gain for legacy controllers.

A standard blocking brake is integrated for static holding, and it can exert up to 45 Nm to secure vertical loads when power is removed. Power conductors are terminated through a connector on side B, simplifying cable routing inside crowded enclosures. The feedback device outputs 3 V/1000 rpm, a signal level matched to conventional analog drive cards. The frame designation 112 indicates the stator cross-section, giving the motor a favorable torque-to-mass ratio for midsize machinery. The motor uses winding code ED, which identifies the electrical characteristics used to match impedance and current ratings.
