Product Description:

The MAC112B-0-GD-3-C-130-A-2-S018 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, this model converts controlled electrical input into precise rotary motion for positioning tasks in automated machinery, material-handling axes, and packaging equipment. Its integrated motor design supports accurate speed control and repeatable motion in systems that rely on external analog command signals.

The motor is equipped with a heavy-duty blocking brake that locks the shaft during power-off conditions, safeguarding vertical or overhung loads. Its brake develops up to 60 Nm of static holding torque, allowing the axis to remain stationary against external forces. A centering pilot of 130 mm aligns the flange accurately with gearbox or machine frames, reducing radial runout. Thermal dissipation relies on natural convection; heat flows from the housing surface to the surrounding air without forced airflow, so installation must provide free space around the frame. Rotor position and speed are monitored through tachofeedback with a second shaft end; the tacho generator sends an analog velocity signal to the drive while the extra shaft extension permits coupling to an external encoder or handwheel.

The motor has a length code of B, which gives moderate continuous torque without enlarging the footprint. Frame size 112 matches standard MAC mounting patterns and corresponds to the motor’s stator diameter class. Power conductors exit through a connector on side A, so cable routing can follow the motor body toward the machine’s primary service corridor. Electromagnetic characteristics are identified by winding code GD, which matches analog drives that supply the voltage and current needed for the intended torque-speed curve while maintaining the standard tacho quality used in the series.
