Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-ED-4-C/130-A-0/WI520V/S005 as part of the MAC AC Servo Motors series. This model is a motor for analog drives intended to produce controlled torque and speed in machine tools, packaging lines, and other industrial automation axes. By receiving current from a matched drive, it converts electrical energy into rotary motion while providing position feedback to close the control loop. Within the series, the unit combines permanent-magnet excitation with low-inertia characteristics to support rapid acceleration profiles common in indexing duties.

The motor uses a centering diameter of 130 mm, providing a precise reference surface that aligns the housing with mounting flanges. Its frame code 112 identifies the external stator size and the related bolt circle for mechanical attachment. The motor has a nominal speed of 3000 rpm, which is the operating point at which rated torque is available. Winding code ED indicates the copper fill and impedance pattern so the companion drive can supply the correct current. Heat is removed through natural convection, eliminating the need for external blowers in enclosures with adequate airflow. The D length code extends the active stack to raise continuous output without changing the footprint.

Power enters through a connector on side A, simplifying cable routing when the motor sits on the right side of a machine bed. Speed feedback is generated by a tachogenerator that delivers 3 V/1000 rpm, and simultaneous incremental signals are produced by the integrated incremental encoder mounted in the standard position. Because the design ships without a blocking brake, axis holding must come from drive torque or an external clamp. This feedback arrangement supports closed-loop speed control in analog drive systems.
