Product Description:

The MAC112D-2-ED-4-C/130-B-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive commands into precise shaft rotation for positioning or velocity control in automated industrial machinery. Position data is provided by a standard incremental encoder, allowing the connected drive to monitor shaft movement during operation. This combination of speed and position feedback suits motion systems that rely on separate feedback channels rather than a single digital communication interface.

Heat is removed through axial surface cooling, where an external blower pushes air along the housing fins; this allows the windings to deliver rated torque without internal fans. The blower requires AC 115 V, so a dedicated low-voltage supply line is needed inside the cabinet. A centering diameter of 130 mm aligns the motor on IEC-compatible mounting faces and helps maintain an accurate mechanical fit. At its nominal speed of 3000 rpm, the D-length stator balances continuous power with moderate inertia for responsive duty cycles. The unit is supplied without a blocking brake, so vertical loads must be held by external mechanics or by drive-generated holding torque when power is removed.

The integrated tacho generator outputs 3 V/1000 rpm, and its standard signal works with legacy analog velocity loops that use separate speed feedback. Winding code ED identifies the electrical characteristics expected by compatible drives, helping the drive match current response to the motor. Power conductors exit on side B through a sealed connector, which can simplify cable routing when space is limited near the drive end. The frame is size 112, giving the motor a shaft height and mounting footprint common to mid-range servo axes. The feedback arrangement also supports the tachogenerator together with either incremental or absolute sensors, so updated feedback hardware can be fitted without changing the basic motor format.
