Product Description:

The MAC112A-0-VD-4-C/130-A-0/WI518LX is a servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is supplied as a motor for analog drives, so it receives continuous voltage or current references from legacy drive cards and delivers proportional torque for industrial positioning and feed axes. In automated packaging lines, printing presses, or handling gantries, the motor converts those analog commands into repeatable shaft motion for controlled axis movement.

A centering pilot of 130 mm keeps the stator housing concentric to attached gearboxes or machine frames, which helps minimize runout at high speed. Cooling relies on natural convection, meaning the frame dissipates its own heat without forced airflow, and this requires unobstructed ambient air around the housing. The armature is designed for a nominal speed of 2000 rpm, giving stable velocity control during normal operation. Winding code VD indicates the electrical characteristics that must match the analog amplifier for proper current regulation. A built-in tacho generator outputs 3 V/1000 rpm, providing proportional voltage feedback so the drive can compare actual speed with its reference signal.

On the mechanical side, frame size 112 and length code A set the overall envelope and inertial behavior of the motor. Power conductors exit through a connector on side A, which can simplify cable routing when the motor is mounted with the shaft facing forward. The unit is supplied without a blocking brake, so a vertical axis must rely on external holding hardware or drive torque while stopped. Standard tacho feedback quality and an incremental encoder with conventional mounting complete the feedback arrangement, allowing either speed control alone or combined position and speed control in systems that still use analog regulation loops.
