Product Description:

The MAC112D-0-HD-3-C/130-A-0/S005 is an AC servo motor from Bosch Rexroth Indramat and is part of the MAC AC Servo Motors series. Designed as a motor for analog drives, it produces controlled torque and speed for indexing tables, material-handling arms, and other precision axes in industrial automation. The built-in tachogenerator, combined with a second shaft end, allows closed-loop speed feedback to the drive while simultaneously passing mechanical motion to auxiliary couplings or external encoders. Its control format suits existing systems that use conventional analog servo amplifiers rather than modern digital feedback networks.

At its nominal operating point, the rotor turns at 1500 rpm, a speed matched to legacy analog velocity loops that expect fixed tachometer voltages and steady proportional feedback. The HD winding code identifies the motor’s electromagnetic constant and helps the drive deliver rated torque at moderate current. Heat is removed through natural convection, so mounting space must let air flow freely around the housing. Alignment with gearboxes or direct-drive loads is aided by a centering pilot of 130 mm on the flange, which helps keep radial runout low. Supply wiring is straightforward because the three-phase power enters through a connector on side A, minimizing cable loops inside the cabinet.

Mechanical holding force is provided entirely by the drive because the unit is built without a blocking brake, which allows manual jogging or back-driving when the application permits it. The tachogenerator produces 3 V/1000 rpm, giving the controller a proportional speed signal with standard quality. Frame designation 112 indicates the stator diameter and establishes interchangeable mounting dimensions across the series, while the overall build is classified as motor length D, which adds extra stack height for higher thermal mass. This configuration is commonly used on machines that still rely on analog servo amplifiers and require a straightforward motor layout for retrofit service.
