Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-2-ED-1-B/130-A-1/I00625 as part of the MAC AC Servo Motors series. This AC servo motor is intended for analog drive packages in factory automation, where it converts electrical commands into controlled rotary motion for positioning and speed-regulated tasks. The unit belongs to the 112 frame class and uses the D length code, which places it in a mid-length housing suited to general-purpose axes. Its layout supports applications that need repeatable motion without requiring a separate feedback package mounted outside the motor.

For mechanical holding during power-off states, a standard blocking brake with a retentive capacity of 45 Nm is fitted, allowing the axis to hold moderate static loads without external clamps. Thermal management relies on axial surface cooling, assisted by an integral fan that operates on AC 115 V, so air is drawn along the housing ribs and heat is removed continuously at rated current. Mounting is aided by a 130 mm centering diameter that aligns the flange to machine interfaces with good concentricity. Position feedback is delivered through incremental encoder feedback, enabling the connected analog drive to process pulse-based position and speed information.

At a nominal speed of 3000 rpm, the rotor operates in a range suited to common automation duties, and winding code ED identifies the electrical characteristics used with this speed class. Power conductors exit through a connector on side A, which helps keep cable routing direct when the motor is installed in line with surrounding machine hardware. For separate velocity monitoring, the built-in tacho generator outputs 3 V/1000 rpm, providing an analog signal proportional to shaft speed. The motor also provides both incremental encoder signals and a tacho signal, so the paired control system can use pulse-based position data alongside an analog speed reference.
