Product Description:

The MAC112B-0-LD-3-C/130-A-2/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analogue drives, it converts commanded current into controlled torque and speed for positioning or velocity loops in automated machinery. Its electromechanical construction allows integration into machine tools, packaging lines, and handling systems where repeatable motion is required.

The frame follows size 112, giving the stator and mounting face dimensions common across the MAC family. A motor length code B extends the active iron stack for increased thermal surface without altering the flange outline, while the centering diameter is 130 mm, ensuring concentric alignment inside a tolerance ring. At a rated electrical frequency the rotor reaches 2000 min⁻¹; this nominal speed defines the velocity setpoint available to the analogue drive when the shaft is unloaded. Heat is removed by natural convection, so airflow around the housing must remain unobstructed for continuous duty. Internal copper characteristics are encoded as winding type LD, establishing the voltage constant and current demand that the drive must match.

For static holding and emergency stops the motor is fitted with a heavy-duty blocking brake rated at 60 Nm; the brake engages mechanically when supply power is removed, preventing back-driving on vertical axes. Motion feedback is supplied by tachofeedback and a second shaft end, delivering an analog velocity signal that the controller can differentiate for closed-loop regulation. That tachogenerator produces 3 V/1000 min⁻¹, enabling direct connection to legacy analogue amplifiers with minimal scaling effort, and its quality classification is standard for the series. Power conductors exit through a connector on side A, simplifying cable routing and keeping encoder leads physically separate from the mains terminals.
