Product Description:

The MAC112D-0-FD-4-C/130-A-0/WI520LV/S005 is an AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. As a motor for analog drives, it supplies closed-loop torque and speed control to positioning axes and material-handling modules in factory automation. It integrates feedback devices that allow the drive to compare commanded velocity with actual shaft motion. That arrangement helps the connected controller maintain stable motion during acceleration, deceleration, and reversing cycles. This makes the unit suitable for repeatable indexing, feed control, and other axis tasks that depend on continuous speed correction.

Its centering diameter measures 130 mm, providing a locating surface for flange mounting. Cooling relies on natural convection, so installation must allow free airflow around the housing. The shaft is machined with a DIN 6885 keyway, allowing standard keyed couplings. A keyed shaft connection helps transmit torque to pulleys, couplings, or gear inputs without requiring a smooth-bore clamping hub. The motor reaches a nominal speed of 2000 rpm, which suits many general-purpose servo axes. For speed feedback, an internal tacho generator delivers 3 V/1000 rpm, and the assembly is prepared for incremental or absolute encoder mounting. The power leads exit through a connector on side A, which can simplify cable routing when the output shaft faces the load.

The motor uses length code D and frame size 112, giving it a compact package compared with larger MAC units while still supporting the output expected from this winding. Winding code FD identifies the electrical design used for this motor family, so the resistance and inductance match compatible analog drive amplifiers. Because no blocking brake is present, holding torque must be provided by the drive or by an external clamping device during standstill. Standard tacho quality and standard encoder mounting complete the feedback arrangement for velocity and position control.
