Product Description:

The MAC112A-0-LD-2-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built as a motor for analog drives, it delivers closed-loop speed and position control when paired with matching drive electronics. The unit supplies rotational energy to conveyor axes, gantry slides, or spindle heads where repeatable velocity and immediate response are required for automated machining and material-handling operations. Its operating role centers on converting controlled electrical input into smooth rotary motion for industrial axes. It responds well to repeated starts, stops, and changing load conditions in production equipment.

A centering diameter of 130 mm allows precise seating in flange brackets without added adapter rings. Heat is removed only through natural convection, so no external blower or liquid circuit is necessary and cabinet airflow remains uncomplicated. Its nominal shaft speed reaches 3000 rpm, giving the motor a speed range suited to many direct-drive or geared axis arrangements. Rotor rotation is monitored by an internal tachogenerator that outputs 3 V/1000 rpm, and drive amplifiers use this proportional signal to maintain commanded speed under changing load conditions. Electromagnetic characteristics are set by winding code LD, which matches the motor to compatible voltage and current ranges.

The motor is supplied without a blocking brake, so vertical or safety-critical axes must rely on external clamping devices when power is removed. Frame designation 112 indicates the stator size, while length index A identifies the shortest magnetic stack used in this frame to help keep mass and inertia low. The short frame length also helps where installation space is limited along the motor axis. Power conductors exit through a connector on side A, which can simplify cable routing when machine access is arranged at that end. Standard tacho feedback supports analog controllers that expect a clean DC velocity signal.
