Product Description:

The MAC090A-0RD-3-C/110-A-0/S001 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed to pair with analog servo drives, it converts command currents into controlled rotation for positioning tasks in packaging lines, handling gantries, and machine-tool feed axes. The motor attaches directly to gearboxes or lead screws to deliver accurate motion under closed-loop feedback. Its servo design supports repeatable starts, stops, and reversals in applications that need stable speed control and precise shaft response.

A nominal speed of 3000 rpm sets the continuous operating ceiling, giving fast traverse rates when matched to suitable mechanics. At zero speed, it can sustain 3.5 Nm while drawing a continuous standstill current of 11.4 A. With a torque constant of 0.34 Nm/A, the drive can relate output torque directly to phase current. Heat produced during operation is dissipated by natural convection, so no external fan or liquid cooling circuit is required. The stator has an inductance of 3.2 mH and a resistance of 0.56 Ω, which affect current rise and response to load changes. A 110 mm centering diameter helps align the flange to mating equipment, and the power connector on side A helps keep cable routing straightforward.

During rapid indexing, the amplifier may apply up to 76 A in short pulses, enabling quick acceleration without immediate thermal saturation. The housing has an IP65 protection rating, allowing installation in dusty or splash-prone areas when the shaft seal is fitted. System dynamics benefit from the rotor inertia of 0.0020 kg·m², which balances responsiveness with load stability. A thermal time constant of 45 min means winding temperature rises gradually, so short overload periods can be tolerated before steady-state heating becomes limiting. The motor weighs 12.5 kg, which helps keep moving assemblies manageable while still providing a rigid mechanical package for industrial axis service.
