MAC AC Servo Motors
The MAC112D-2-FD-4-C/130-A-0/DI520/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is specified as a motor for analogue drives, meaning velocity or torque commands are provided as continuous voltage rather than digital field-bus telegrams. The design employs winding code FD and an incremental encoder with shock-damped mounting so the rotor position is delivered to the controller for closed-loop motion. By converting regulated current into mechanical rotation, the unit serves indexing tables, form-fill-seal equipment, and other automation axes that retain analog interface requirements.
Electrical output is defined by a continuous torque at standstill of 38.0 Nm, giving the axis the ability to hold static loads without overheating. To sustain this torque the winding must carry a continuous current of 56.0 A, and copper losses are limited by a winding resistance of 0.110 Ohm measured at 20 °C. For rapid acceleration the drive may inject up to 260 A as a peak pulse; this short-term surge overcomes inertia before thermal limits intervene. The torque produced for each ampere is characterized by a constant of 0.760 Nm/A, a value used by the amplifier to linearize current commands into predictable mechanical effort. Together, these ratings define the motor’s steady-state loading envelope and transient headroom.
Heat generated by those currents is removed through Axial Surface Cooling, assisted by an external AC 115 V blower that directs air along the housing fins. The frame centers on a 130 mm pilot diameter, ensuring alignment with gearboxes or mounting flanges, and the overall mass of 59 kg contributes to vibration damping. A thermal time constant of 120 min indicates that winding temperature rises slowly, allowing extended duty cycles near the specified 2000 min⁻¹ nominal speed without frequent cool-down periods. Additional attributes such as a rotor inertia of 0.0230 kg·m², tachometer voltage of 3 V/1000 min⁻¹, and axial power connection on side A complete the mechanical and feedback profile.
