Product Description:

The MAC112A-0-VD-4-C/130-A-0/WI524LV/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it acts as the rotary actuator in closed-loop positioning and speed-control loops used across automated machinery. The unit combines a predefined 112 frame size with an A-length housing to provide a balance of torque capability and compact installation inside industrial automation cells.

The mechanical interface starts with a centering pilot of 130 mm, allowing the motor flange to seat squarely against machine frames and maintain alignment under load. A nominal shaft speed of 2000 rpm matches the frequency range delivered by analog amplifiers, giving predictable velocity control. Cooling depends solely on natural convection, so the housing fins must remain unobstructed to let ambient air carry away losses. Because the motor has no holding brake, static torque must be sustained by the drive or by external locking mechanisms when power is removed. Torque is transmitted through a shaft machined with a DIN 6885 keyway, permitting standard keyed hubs to be fitted without custom machining.

For speed feedback, the tacho generator outputs 3 V per 1000 rpm, providing a linear voltage signal that analog controllers can interpret directly, and its tacho quality is standard for general-purpose accuracy. Position data is supplied by an incremental encoder installed in the standard rear mounting, enabling higher-resolution monitoring when the axis is integrated into digital control loops. Main power reaches the stator windings through a connector on side A, keeping high-current leads separate from sensor cabling. Magnetic characteristics correspond to winding VD, so matching drive settings can apply the correct current limits and field orientation.
