Product Description:

The MAC112C-0-HD-2-C/130-A-0/S05 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive-amplifier current into precise shaft rotation for positioning, conveying, or spindle functions in automated machinery. The unit uses resolver and tachometer feedback so the control loop can monitor actual speed while the machine regulates torque. It is intended for integration with a separate drive amplifier rather than standalone operation, which is typical for analog motion systems.

The mechanical interface centers on a 130 mm pilot diameter that aligns the housing to the driven load and maintains concentricity during acceleration. This frame is designed for continuous operation without a blocking brake, so holding torque must be supplied externally when the drive is disabled. Rotor heat is dissipated by natural convection, eliminating fans and reducing service requirements in sealed cabinets. Speed information is provided through tacho feedback, enabling the analog controller to sense real-time velocity against its reference. Under nominal load, the motor reaches 2000 rpm, a speed that matches many machine-tool and material-handling duty cycles.

The stator winding code HD sets the voltage constant and current demand for the matching drive amplifier, while the overall package remains in the compact envelope of motor size 112 with length code C. Power conductors are routed through a connector on side A, allowing cable runs to stay clear of moving axes when the motor is flange-mounted. The tachogenerator outputs 3 V/1000 rpm, giving the controller a linear feedback signal that scales directly with shaft speed for stable closed-loop regulation. The compact housing helps the motor fit installations where mounting space and cable routing are limited. This layout is suitable for legacy analog motion systems that rely on voltage and current interfaces instead of digital fieldbus communication.
