Product Description:

The MAC112D-0-ED-3-C/130-B-2/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for use with analog drive controllers where precise torque and speed regulation are required for packaging lines, conveying axes, and general motion tasks. By translating current setpoints into mechanical rotation, the unit provides closed-loop actuation for machinery that must maintain consistent positioning under varying load conditions. Stable response during starts, stops, and speed changes supports use in general industrial automation.

Mechanical holding capacity is supplied by a heavy-duty blocking brake that applies up to 60 Nm of static torque, preventing back-driving when power is removed. The motor mounts against frames with a centering pilot of 130 mm, a dimension that aligns the stator housing accurately in the machine bore. Heat generated by the windings is dissipated through natural convection, so no external blower is required and installation remains simple and maintenance-free. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, enabling direct coupling to gear stages or belt transmissions that expect standard high-speed input. Passive cooling also reduces the number of external components around the motor housing.

Signal integrity for velocity loops is provided by tacho feedback and a second shaft end. This combination delivers the standard tacho quality required by the drive while allowing an auxiliary encoder or mechanical load to be coupled to the opposite side of the rotor. The tacho generates 3 V/1000 rpm, a scaling that the analog controller interprets directly without additional amplification. Power conductors are routed through a connector on side B, which helps simplify cable routing in typical machine layouts. Electrical characteristics follow winding code ED, and the mechanical envelope corresponds to motor length D and size 112.
