Product Description:

The MAC112D-0-HD-3-C/130-A-1/S021 is an AC servo motor developed by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive commands into precise rotary motion for positioning or speed-regulated axes in automated machinery. By integrating a permanent-magnet rotor with sensor feedback hardware, the unit supports closed-loop control for packaging lines, material-handling stages, and general machine-tool functions. This arrangement allows the connected drive to correct speed deviations quickly during changing load conditions.

This model uses winding code HD and is built in the D length class, giving a housing that balances torque output with overall installation space. A centering diameter of 130 mm aligns the flange during mounting, while the rated speed of 1500 rpm gives the motor a steady operating point for speed-controlled applications. Cooling relies on natural convection, so heat is dissipated through the ribbed stator surface without auxiliary fans or liquid circuits. This cooling method helps keep the installation simple and leaves more space around the motor for standard cable routing and nearby machine components.

The motor incorporates a blocking brake that can hold loads with a torque of 45 Nm when power is removed. Electrical power is routed through a plug positioned on connector on side A, which can simplify cable entry on machines that group motor leads along one side of the axis. Size code 112 places the motor within its stator diameter family, and the unit also uses tacho feedback on a second shaft end for analog velocity loops. The tacho output of 3 V/1000 rpm provides a clear speed signal for compatible analog control circuits, which helps the drive maintain stable velocity feedback during continuous operation.
