Product Description:

The MAC112D-0-HD-1-B/130-A-0/I01250/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it receives sinusoidal current from a stand-alone power stage and delivers regulated mechanical power to gantries, presses, and transfer stations. Its task in industrial automation is to supply controllable torque and speed so that closed-loop motion axes can follow programmed profiles with repeatable accuracy.

The mechanical interface determines how the unit is installed. A centering pilot of 130 mm aligns the flange with precision mounting bores and keeps radial runout low. Frame designation 112 indicates the outer stator dimension and helps with enclosure spacing. Length code D extends the active iron stack, increasing continuous torque without altering the mounting pattern. Heat generated by copper losses is removed through natural convection, so clearance around the housing is required and no external blower is needed. Under nominal excitation, the rotor reaches 1500 rpm, a speed that suits gear ratios common in indexing tables and feeder rolls while avoiding high-frequency resonance.

The motor uses winding code HD, which suits intermediate-voltage systems and moderate current demand. Position data are delivered by incremental encoder feedback, allowing legacy analog controllers to close velocity and position loops with standard TTL signals. For tachometer redundancy, the motor provides 3 V/1000 rpm of tacho voltage, enabling precise speed estimation without relying solely on the encoder. Power conductors leave the housing through a connector on side A, simplifying cable routing in cabinets arranged along the machine's left edge. The unit is supplied without a blocking brake, so holding torque must be established by the drive or external clamping devices.
