Product Description:

The MAC112D-0-ED-4-C/130-A/WI520LX/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as a rotary actuator for industrial automation systems that rely on analog velocity and current loops. When paired with a compatible drive, the unit supplies controlled torque and speed for indexing tables, pick-and-place modules, and general transfer equipment. It translates control signals into precise mechanical motion while using a standardized mounting interface, and its hardened shaft and IP65-sealed housing support continuous duty in dusty production zones.

The 112 frame size gives the motor a larger stator diameter and increases magnetic air-gap area, supporting higher continuous torque than smaller housings. With length code D, the laminated core is extended, raising the motor’s thermal mass for improved overload capability. A nominal speed of 3000 rpm aligns with common gear ratios used on conveyors and carton erectors, limiting the need for additional pulleys. The flange’s 130 mm centering diameter provides a tight H7 fit on the machine wall to keep the rotor concentric and minimize bearing side loads. Winding code ED indicates the resistance and inductance values so the associated analog amplifier can deliver rated current without exceeding its voltage headroom.

Thermal exchange relies on natural convection, so the motor should be mounted where ambient air can circulate freely around the ribs to avoid derating. The mains leads terminate through a connector on side A, keeping high-power wiring separate from feedback cabling when multiple axes are stacked. Closed-loop control is backed by tacho feedback with an incremental or absolute encoder, depending on the matching drive card. The built-in tacho produces 3 V/1000 rpm, and the signal is described as standard quality for general-purpose positioning tasks in analog drive systems.
