MAC090A-0-RD-4-C/110-A-0/WI574LV

The Bosch Rexroth Indramat MAC090A-0-RD-4-C/110-A-0/WI574LV is a high-performance member of the MAC AC Servo Motors series, designed for precision motion control in demanding industrial applications. This brushless permanent magnet motor features robust construction and electronic commutation to deliver consistent performance with minimal maintenance. Equipped with an incremental encoder as standard, the MAC090A-0-RD-4-C/110-A-0/WI574LV ensures accurate position feedback throughout its operational envelope. The motor offers a nominal speed of 3000 rpm and continuous torque capability at standstill of 3.5 Nm, making it suitable for acceleration-intensive tasks. The absence of a built-in blocking brake simplifies the design while maintaining high reliability and uptime.

Technical specifications for the MAC090A-0-RD-4-C/110-A-0/WI574LV are optimized for efficient power transmission and thermal stability. Continuous current at standstill is rated at 11.4 A, with a maximum peak of pulse current of 76 A to accommodate dynamic load changes. The windings exhibit an inductance of 3.2 mH and a resistance of 0.56 Ohm at 20°C, supporting precise current control and low electrical losses. A torque constant of 0.34 Nm/A at 20°C ensures predictable torque output, while the rotor moment of inertia of 0.002 kg·m² underpins rapid acceleration and deceleration profiles. The motor’s thermal time constant of 45 min allows controlled temperature rise during high-duty cycles.

Operational features emphasize reliability and performance stability under extended use. The MAC090A-0-RD-4-C/110-A-0/WI574LV employs Natural Convection cooling, eliminating the need for forced-air systems and reducing maintenance complexity. Its brushless design and lifelong lubricated bearings provide zero-maintenance operation, bolstering uptime in continuous-duty scenarios. With a mass of 12.5 Kg and a compact footprint defined by a motor size of 90 and motor length A, installation flexibility is maximized. The integrated incremental encoder supports closed-loop control with fine resolution, while the absence of a blocking brake streamlines mechanical integration.

System integration is seamless with Rexroth Indramat drive controllers such as TDM, DSC, and KDS, enabling advanced features like auto-tuning and real-time diagnostics. The MAC090A-0-RD-4-C/110-A-0/WI574LV interfaces directly with standard servo amplifiers, simplifying wiring and commissioning. Target applications include CNC machine tools, robotics, packaging systems, and textile machinery where precise torque control and rapid dynamic response are critical.
