Product Description:

The MAC112B-1-LD-4-C/180-A-0/W1524LV/S001 is a servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is used with analog drives and supplies precise rotary motion for positioning or velocity control tasks in automated machinery. By pairing with legacy drive amplifiers, the unit converts electrical commands into repeatable shaft movement, allowing conveyors, tooling axes, and material-handling stations to maintain consistent cycle times.

The motor employs AC 230 V blower power to move air along its housing, and this forced flow works with its axial surface cooling layout to remove heat from the stator laminations. A centering flange of 180 mm sets the pilot diameter for mounting and establishes radial alignment between the motor and adjoining mechanics. Inside the housing, winding code LD identifies the copper distribution and impedance values that let the rotor reach a nominal speed of 2000 rpm while staying within the thermal index of the insulation system. Tachofeedback produces a calibration signal of 3 V/1000 rpm, which drive electronics use to compare commanded velocity with actual shaft speed. Incremental or absolute encoder signals are routed in parallel with the tacho so that position data remains available if the analog channel is lost. The motor length is noted as B, giving a mid-range stack height that balances torque density with overall frame depth.

The motor has no blocking brake, so external mechanical measures are required when the application needs static holding torque. Three-phase power enters through a connector on side A, which simplifies cable runs in cabinets where the shaft faces forward. Frame designation 112 describes the stator diameter family and aligns the motor with couplings sized for this body. Standard tacho feedback, encoder feedback, and the B-length stack suit general-purpose industrial motion.
