Product Description:

The MAC112D-2-FD-4-C/130-A-0/WI is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Delivered for analog drive systems, it supplies controlled torque and speed to automated machinery, acting as the primary mechanical output stage in production lines and machine tools. The unit follows the series format that pairs a permanent-magnet rotor with electronic commutation to achieve stable, feedback-regulated motion.

Mechanical dimensions and thermal management determine where this motor can be installed. An external blower rated at AC 115 V drives air through the fins that form the axial surface cooling path, so the stator can dissipate heat even at continuous current. The flange carries a centering recess of 130 mm, allowing direct alignment with precision gearboxes or mounting plates. Within the MAC coding, the frame corresponds to size 112 and length D, a combination that balances inertia with a compact footprint. Under nominal excitation, the rotor reaches 2000 rpm, giving adequate speed range for feed axes while maintaining torque at low speed. Because no blocking brake is fitted, external holding devices are required when vertical loads are involved.

Electrical integration is straightforward because the power leads terminate in a connector on side A, keeping cables on the same face as the blower. Rotor position and velocity are monitored through tachofeedback. The tachogenerator produces 3 V/1000 rpm with standard tracking accuracy, and the electronics can also read an encoder signal. The chosen position sensor in this version is an incremental encoder with standard mounting, enabling legacy analog controllers to process quadrature pulses without protocol conversion. Winding code FD indicates the coil impedance and matches the motor to drive modules that can supply the required current profile.
