Product Description:

The MAC112B-0-PD-4-C/130-B-1/AM164SG is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, the unit converts electrical power into controlled rotary motion for industrial positioning, indexing, and speed-regulated tasks. A standard blocking brake is integrated so mechanical loads remain fixed whenever the drive is de-energized. Combined tachometer and encoder feedback enables the controller to track actual shaft conditions during operation.

The blocking brake supplies a holding torque of 45 Nm, preventing axis drift on vertical or high-inertia loads. Shaft rotation under continuous duty is rated at 1500 rpm, aligning with mid-speed machining and conveyor requirements. Internal heat is removed by natural convection, so no external blower or liquid circuit is required, which simplifies the cooling arrangement. A centering diameter of 130 mm registers the flange accurately against mounting faces and maintains concentricity with driven equipment. Power conductors exit through a connector on side B, allowing cable trays to be routed along the non-drive end while keeping the encoder side unobstructed.

Rotary feedback is delivered by an integrated absolute encoder that reports the shaft position without requiring a homing cycle after power-up. For velocity loops, the tachogenerator provides a signal of 3 V/1000 rpm, giving proportional speed information to analog regulators. The PD winding code indicates resistance and inductance values suitable for drives that supply moderate current with accurate phase control. The motor has a frame size of 112, providing the mechanical envelope needed for its mounting and operating characteristics. Its B length class balances continuous torque capability against overall depth when space behind the mounting plate is limited. The centering interface supports accurate alignment with connected machinery, while the side-mounted power connection keeps conductors away from the primary feedback components.
