Product Description:

Bosch Rexroth Indramat’s MAC112D-0-ED-4-C/130-A-0/WI511LV/S005 is an AC servo motor in the MAC AC Servo Motors series. The unit is supplied as a motor for analog drives. It is used wherever precise speed and torque regulation are required for coordinated motion axes in industrial automation. It is well suited for positioning tasks that rely on stable closed-loop response during changing load conditions.

The motor has size 112, a frame class that determines mounting geometry and shaft height. Winding code ED identifies the copper fill and impedance values used by analog drive amplifiers. A centering diameter of 130 mm aligns the stator housing with machine flanges, while the nominal operating speed of 3000 rpm allows direct coupling to gear stages or belt transmissions without overspeeding the rotor. For velocity feedback, an internal tacho generates 3 V/1000 rpm, and this voltage is read by the drive to stabilize closed-loop speed. The motor length is coded as D, and the unit has no blocking brake, so holding force must be provided externally when the axis is unpowered. Tacho quality is listed as standard, reflecting normal linearity and temperature drift values for general-purpose regulation.

Thermal management relies on natural convection, which disperses losses through the aluminum frame and keeps installation simple in cabinets without forced airflow. Rotary motion is transmitted through a shaft machined with a DIN 6885 keyway, which supports positive torque transfer to hubs or pulleys. Position feedback is collected by an incremental encoder that mounts in the standard housing interface and works with the tacho signal for motion control. Power conductors enter through a connector on side A, keeping power and signal cabling on the same face of the motor and simplifying cable routing.
