Product Description:

The MAC112D-0-ED-1B-130-A-0/I1250/S05 is an AC servo motor produced by Bosch Rexroth Indramat for closed-loop motion systems. It belongs to the MAC AC Servo Motors series and serves as the electromechanical actuator in positioning axes that are driven by analog servo amplifiers. Within automated assembly lines or material-handling gantries, the motor converts regulated current into precise rotary motion. It supplies the torque and speed needed for repeatable, high-cycle operation in machinery that depends on stable motion control.

The unit uses a frame with a 112 mm stator diameter, and this mechanical envelope is identified as motor size 112. The active magnetic stack is extended to the D length, so the motor can deliver higher continuous torque than shorter variants while maintaining the same mounting pattern. A nominal speed rating of 3000 rpm allows direct coupling to gearboxes or belt drives that expect standard industrial shaft speeds. This layout supports integration into axes that need a larger torque reserve without changing the basic motor footprint.

The housing is cooled by natural convection, so installation clearances must permit unobstructed airflow around the motor housing rather than rely on forced ventilation. Rotor position feedback is supplied through incremental encoder feedback, giving the drive controller quadrature signals for velocity and position loops without absolute multi-turn data. Compatibility with analog drives means the motor accepts command currents that are proportional to the desired torque, fitting legacy control architectures that rely on analog references. The electrical characteristics follow winding code ED, which uses a stator wire gauge and turn count that match the back EMF, resistance, and inductance to the voltage and current ranges of the corresponding MAC drive modules.
