Product Description:

The MAC112A-0-VD-4-C/130-A-0/WI511LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It operates in analog drive loops, where a velocity or current command from the drive amplifier is translated into controlled mechanical power on the machine side. The motor’s frame, feedback package, and electrical winding are coordinated so motion controllers can regulate axis speed and position in packaging equipment, material-handling stations, and general machine tools.

The machining flange seats against a centering recess that measures 130 mm, keeping the rotor axis concentric with gearboxes or direct-drive couplings. The frame designation of 112 indicates the square stator size and mounting bolt patterns shared across this motor class. Heat is removed solely by natural convection, so the motor can be installed without forced-air ducts when ambient airflow is sufficient. A base speed of 2000 rpm establishes the velocity at which rated torque and voltage coincide, simplifying drive scaling in systems that demand constant mechanical output up to this point. For speed feedback, the built-in tacho generator delivers 3 V/1000 rpm; this proportional voltage lets the analog controller sense shaft velocity directly and adjust current for closed-loop regulation.

Torque is transferred through a DIN 6885 keyway cut into the shaft, allowing a rigid connection to pulleys or couplings while preventing slip under peak load. Power conductors reach the stator windings through a connector on side A, so cable trays can remain on the same side as the drive cabinet. Position feedback is handled by an incremental encoder installed with the standard mounting interface, giving the control loop fine resolution while the tacho supplies velocity data. Electrical response is governed by winding code VD, a coil configuration that sets resistance, inductance, and nominal current for compatibility with designated analog amplifiers. The motor is supplied without a blocking brake, so external mechanics or continuous drive torque must hold vertical or suspended loads when power is removed.
