Product Description:

The MAC112B-0-LD-1-B/130-A-0/I625/S05 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it supplies closed-loop torque and velocity control to machine tools, handling systems, and general automation axes. The unit translates drive commands into mechanical rotation and feeds speed information back to its controller, fulfilling the role of a precision actuator in industrial motion tasks. It also accepts the analog current commands used by legacy Rexroth servo amplifiers, making it suitable for systems that rely on conventional servo regulation rather than newer digital interfaces.

The motor uses frame size 112, giving the stator housing a diameter compatible with mid-range machine frames, while the centering pilot ring measures 130 mm for accurate seating on gearboxes or mounting flanges. Its rated speed is 2000 rpm, which suits many conveyor, feed, and spindle applications. For speed verification, the built-in tacho generator outputs 3 V/1000 rpm, and simultaneous position data is delivered through incremental encoder feedback to keep the analog drive synchronized during changing load conditions. Thermal management relies on natural convection, so no external blower or liquid circuit is required. Heat dissipates through the finned housing under normal ambient conditions, which helps simplify installation where auxiliary cooling equipment is not desired.

As a length code B unit, the motor has a compact axial length that helps it fit into tighter installation spaces while maintaining the continuous torque associated with the LD winding set. Power conductors connect through a connector on side A, which can simplify cable routing when the motor is mounted with the shaft pointing forward. Winding code LD identifies the electrical characteristics used with compatible analog amplifiers that supply the required current. The motor is supplied without a blocking brake, so any holding function must be provided by external mechanics or by drive torque. This arrangement is often used where the axis does not need mechanical holding at standstill or where a separate holding device is already part of the machine design.
