Product Description:

The MAC112D-0-ED-3-C/130-A-0/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed to pair with analog servo drives, it converts command voltages into tightly regulated shaft motion for positioning tables, feeders, and similar automation axes. Its construction supports rapid acceleration, accurate speed following, and continuous duty in industrial environments where repeatable motion profiles are required. This makes the motor suitable for applications that involve frequent starts, stops, and speed changes during normal machine operation.

A centering diameter of 130 mm aligns the stator housing to machine frames and keeps the rotor concentric with coupled loads. Heat is removed through natural convection, so no external blower or liquid circuit is needed and cabinet airflow remains uncomplicated. The three-phase power leads attach through a connector on side A, which can simplify cable routing in multi-axis cabinets. The winding is tuned for a nominal speed of 3000 min⁻¹, giving the drive a predictable velocity constant for machining and handling tasks. A built-in tachogenerator produces 3 V/1000 min⁻¹ of feedback voltage for closed-loop speed regulation, which helps reduce steady-state error and overshoot.

The motor frame is size 112 with length code D, and this housing size affects flange pitch, stack depth, and thermal mass relative to other MAC variants. Electrical parameters follow winding code ED, which sets the resistance and inductance values used by compatible drive cards. The motor has no blocking brake, so vertical or load-holding axes must rely on external clamps or continuous torque from the control loop. The feedback arrangement includes tachofeedback and a second shaft end for mounting an encoder or a manual handwheel. Tacho quality is standard, which suits general-purpose accuracy requirements.
