Product Description:

The MAC112A-0-VD-4-C/130-A-0/WI518LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it delivers closed-loop motion in machine tools, printing lines, and general automation equipment. By combining tachometer and encoder feedback with a field-optimized winding, the unit translates drive commands into controllable shaft torque and speed for positioning and velocity regulation. Its integrated feedback package also allows the paired amplifier to monitor motor response continuously during acceleration, deceleration, and direction changes.

The mechanical interface uses a centering diameter of 130 mm, which aligns the flange with precision gearboxes and bearing blocks. Heat is removed through natural convection, so no external blower or liquid circuit is required. This passive cooling arrangement keeps the motor layout simple and suits installations where surrounding air can carry heat away from the housing. The electromagnetic profile follows winding code VD, matching resistance and inductance to analog amplifiers in the same series. Nominal operating speed reaches 2000 rpm, giving stable motion for mid-range feed axes, and the motor has no blocking brake, so static holding torque must come from the drive or an external clamp.

Velocity feedback is produced by an internal tacho generator that supplies 3 V/1000 rpm, allowing the connected drive to track motor speed with a direct analog signal. Power conductors exit through a connector on side A, which can simplify cable routing along the machine frame and away from adjacent components. The frame designation uses motor size 112 with length code A to provide a compact profile for general-purpose servo axes. Position control data comes from an incremental encoder mounted in the standard housing, allowing compatible analog servo controllers to process feedback for accurate speed trimming and repeatable axis movement. Tacho quality is standard for general-purpose axis control.
