Product Description:

The MAC112D-0-ED-3-C/180-A-2/S029 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it is used on positioning axes and cyclic motion sequences where torque is regulated by an external drive amplifier. The model has size 112 with length D, and its centering pilot mates directly with precision machinery housings for accurate installation. This arrangement helps the motor fit machine assemblies that need repeatable alignment and stable shaft coupling during continuous operation.

A heavy-duty blocking brake is installed to hold loads when power is removed, and the brake can resist up to 60 Nm of countertorque. The mounting face uses a 180 mm centering diameter to help maintain coaxial alignment between the stator and coupled shafts. Heat is dispersed through natural convection, so no external blower or liquid circuit is required. The motor includes tacho feedback and a second shaft end, so the drive receives a speed signal while the extra shaft extension remains available for an auxiliary encoder or coupling. Under rated excitation, the motor reaches a nominal speed of 3000 rpm, which suits medium-inertia loads that require rapid indexing without overshoot.

The power leads exit through a connector on side A, allowing cable routing to follow the machine’s fixed wiring trays without crossing moving members. For velocity feedback to the external controller, the built-in tacho generator outputs 3 V/1000 rpm, a signal level compatible with standard analog drive cards. Electromagnetic behavior is tied to winding code ED, which sets the coil impedance and thermal response expected by the matching drive. This combination supports stable closed-loop operation in assembly lines, gantries, and transfer stations that run through repeated duty cycles and frequent speed changes. It is suited to automated stations where smooth speed regulation and reliable standstill holding are both required.
