Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-ED-1-B/130-A-0/-I01250/S05, an AC servo motor in the MAC AC Servo Motors series. The unit is intended for analog drives and supplies precise torque and speed control for machine tools, printing lines, and other automated equipment. Integrated feedback allows the paired drive to monitor motion continuously during closed-loop operation. This type of motor is suited to axes that require repeatable acceleration, steady speed regulation, and consistent response to changing load conditions.

Its cooling relies on natural convection, so the housing must have free airflow for heat dissipation. A centering diameter of 130 mm aligns the motor to standard IEC flanges and helps maintain concentricity during rotation. The nominal speed rating is 3000 rpm, which is the reference speed for rated motor operation. For velocity feedback, an internal tachogenerator outputs 3 V/1000 rpm, providing an analog signal that is proportional to shaft speed. That signal gives the drive a simple way to track motor speed across normal operation. Winding code ED indicates the electrical resistance and inductance values expected by a compatible analog drive amplifier.

The motor has no blocking brake, so load holding must be provided externally when power is removed. Frame size 112 sets the mounting geometry, shaft height, and allowable radial load range for this housing. Rotor position is reported through incremental encoder feedback, so the controller receives fine-resolution count data in addition to the tachogenerator signal. Line power reaches the stator windings through a connector on side A, allowing the power cable and encoder harness to leave from the same end of the motor. Keeping both cable sets on one end can simplify routing in compact machine layouts and reduce bend stress near the connection point.
