Product Description:

The MAC112C-0-HD-4-C/130-A-2/WI1522LV/S013 AC servo motor is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts current-loop commands into controlled shaft rotation for machine tools, gantry axes, and positioning stages. Integrated electromechanical feedback works with the blocking brake so the unit can alternate between commanded motion and secure load holding during pauses, which is useful on axes that must stop accurately before the next machine step begins.

A heavy-duty blocking brake is fitted to arrest the shaft when power is removed, and its stopping capacity is 60 Nm so the motor can secure moderate-inertia loads without external clamps. The flange has a 130 mm centering diameter, providing a reference surface that supports concentric alignment with gearboxes or machine frames during installation. Thermal management relies on natural convection, eliminating the need for added fans or coolant lines and allowing installation where airflow arrangements must remain simple. The motor uses winding code HD and delivers a nominal speed of 2000 rpm, enabling direct coupling to medium-speed mechanical transmissions without an intermediate reduction stage.

The unit uses motor size 112, which sets the stator diameter and indicates the torque capacity available from this frame and winding combination. Power enters through a connector on side A, keeping the feedback end free and helping route motor leads away from adjacent axis hardware in multi-axis assemblies. For speed feedback, a tachogenerator delivers 3 V per 1000 rpm, giving analog velocity signals that remain proportional to shaft speed and complement the position data from the incremental encoder with standard mounting. The encoder supports closed-loop position monitoring, while the tachogenerator supplies a continuous speed reference to the analog drive.
