Product Description:

The MAC112D-0-ED-4-C7130-A1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive packages where precise torque and velocity control are required in automated machine axes. By converting electrical command signals into controlled mechanical rotation, it serves as the drive element in feed axes, gantry tables, and forming equipment. This type of motor is commonly used where motion must remain smooth during frequent starts, stops, and direction changes.

Its centering pilot is machined to 130 mm, allowing consistent shaft alignment against precision gearbox or mounting flanges. Heat generated in the stator is dissipated through natural convection, so the motor can be installed without dedicated airflow hardware. Rated speed capability reaches 3000 rpm, which supports fast travel on ball-screw or belt-driven axes when the transmission is sized correctly. The internal tacho generator delivers 3 V/1000 rpm, providing a linear feedback signal for analog speed monitoring. Magnetic behavior is linked to winding code ED, which establishes the electrical characteristics expected by the matching drive. Because cooling is passive, the housing suits layouts where fan maintenance is undesirable and airflow management must remain simple.

Position and speed signals can be supplied through tacho feedback or by an incremental or absolute encoder, allowing the sensing method to match the control layout. The stator frame uses size 112 with length index D, giving the motor a larger housing than shorter variants and supporting higher continuous torque in the same product line. Power conductors enter through a connector on side A, which helps keep cable routing on the drive end of the machine and makes motor removal easier in crowded installations. The available feedback choices also let the motor work with different controller arrangements while keeping the same basic mounting format. This arrangement is useful in retrofit systems where existing panel layouts, couplings, and cable paths need a motor that fits established mounting practices.
