Product Description:

The MAC112D-0-ED-2-C/130-B-1/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drives, the unit converts command voltages from a drive controller into regulated rotary motion for positioning and speed control tasks in automated production cells. By integrating permanent-magnet excitation with internal sensors, the motor supplies consistent torque and velocity to machine axes without requiring external transducers. This arrangement supports repeatable motion on packaging, transfer, and indexing equipment where stable closed-loop response is required during frequent speed changes.

The motor includes a standard blocking brake rated for 45 Nm that secures the shaft against back-driving whenever power is removed. A nominal speed of 3000 min⁻¹ aligns the rotor with common industrial drive outputs, allowing direct coupling to reduction gearboxes. This speed level suits many machine axes that operate with standard gear ratios and moderate load inertia. Heat generated in the stator is carried away through natural convection, so no forced-air plenum is necessary inside tight cabinets. Mechanical alignment is simplified by a centering diameter of 130 mm, which provides a precise reference surface for flange mounting. Electrical characteristics follow winding code ED, so resistance and inductance values match the corresponding MAC amplifier.

The tacho generator, classified as standard quality, outputs 3 V per 1000 min⁻¹, and the motor is equipped with tacho feedback. Power conductors exit through a connector on side B, enabling cable routing alongside the fixed machine harness and helping keep the connection area organized. The enclosure length code D provides a longer housing within this motor platform, which supports the installed rotor and stator package. Frame size 112 standardizes the flange pattern across the MAC family and helps maintain compatibility with matching mounting surfaces.
