Product Description:

The MAC115D-1-DS-S-F/180-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is built for analog drive systems, where a drive amplifier converts command voltages into torque and speed for automated axes such as gantries, presses, or material-handling modules. The motor’s mechanical interface, electrical feedback, and forced-air cooling support continuous closed-loop motion in industrial automation environments where steady speed control and repeatable positioning are required. This arrangement allows the motor to work with external analog electronics while keeping the actuator package compact at the machine axis.

The motor frame is designated size 115, and the stator stack coded D gives a longer active length for higher continuous output and improved heat dissipation over shorter stack lengths. Its nominal speed of 2000 rpm is the synchronous operating point used by analog velocity loops, which helps the drive maintain consistent running speed during normal operation. Thermal loading is controlled by axial surface cooling; an external blower running on AC 230 V pushes ambient air along the housing to remove losses before they reach the winding insulation. Accurate centering during mounting is provided by a 180 mm pilot diameter, allowing rigid coupling to gearboxes or precision brackets. Because a blocking brake is not present, holding duty must be achieved through the drive or an external clamp.

The power conductors exit through a connector on side B, keeping cable routing clear of the cooling airflow and leaving more free space around the rear of the motor. Winding code DS indicates the electrical values that the amplifier must match for stable torque production and predictable current response. Speed feedback comes from an integrated tacho generator that delivers 3 V/1000 rpm, and its calibration is complemented by improved smooth-running quality to reduce velocity ripple in low-speed machining, indexing, and other applications that depend on uniform rotation. The tacho signal gives the amplifier a direct speed reference for closed-loop correction during load changes.
