Product Description:
The MAC112A-0-VD-3-C/130-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts commanded armature current into regulated shaft torque and speed for precision positioning, indexing, or feed functions found in automated cells and machine tools. Its mechanical form is compatible with standard flange interfaces so the motor can mount directly to gearboxes, ball screws, or pulleys without extra adapters. This arrangement supports compact axis layouts where accurate motion and straightforward mechanical integration are both required.
Mechanical holding of the shaft is provided by a blocking brake that sustains 45 Nm when engaged, allowing vertical axes to remain stationary after power removal. Accurate centering during installation is aided by a 130 mm pilot diameter on the front flange, which aligns the stator housing to the driven element. The motor is cooled by natural convection, so heat leaves the surface without forced airflow. Under rated excitation, the rotor reaches 2000 rpm, a speed suited for medium-inertia loads that require smooth motion. A built-in tachogenerator outputs 3 V/1000 rpm, giving the analog drive continuous velocity feedback for closed-loop regulation.
The electromagnetic package uses winding code VD, which matches the resistance and inductance values expected by the analog amplifier. Power enters through a connector on side A, which can simplify cable routing when the motor is mounted against a machine wall or inside a narrow enclosure. Frame designation 112 corresponds to the motor size used for the housing and mounting pattern, while length class A keeps the unit short enough for compact machine sections. Tachogenerator signals are available through tachofeedback with a second shaft end, allowing speed feedback to be taken from the rear of the motor. The tacho is graded as standard quality, providing stable velocity data for medium-precision speed loops in assembly and packaging equipment.
