MAC090C-0-KD-4-C/110-B-0/WI531LX

The Bosch Rexroth Indramat MAC090C-0-KD-4-C/110-B-0/WI531LX is a precision-engineered member of the MAC AC Servo Motors series, designed for high-performance motion control in demanding industrial applications. This MAC Permanent Magnet Motor offers a nominal motor speed of 2000 min-1 and a robust continuous torque at standstill of 10.4 (16.0) Nm to support heavy-duty load profiles. Integrated within the housing is an incremental encoder with standard mounting, ensuring high-resolution feedback for closed-loop applications. Cooling is achieved via natural convection to maintain consistent thermal performance without auxiliary systems. The motor’s compact motor size 90 and motor length C allow seamless integration into existing machine architectures.

The technical specifications of this servo motor emphasize reliability and precision: a continuous current at standstill of 17.0 (26.1) A delivers steady torque output, while the maximum peak of pulse current of 125 Amperes enables rapid acceleration bursts when required. The torque constant at 20 °C of 0.68 Nm/A and a windings resistance at 20 °C of 0.60 Ohm are closely matched with a windings inductance of 3.6 mH to ensure predictable dynamic response. A rotor moment of inertia of 53×10^-4 kg·m² provides fine control over position and velocity transitions. With a thermal time constant of 60 (45) minutes, the motor can tolerate sustained operation at high currents without exceeding safe temperature limits. Weighing 23 kg, it strikes a balance between mechanical robustness and manageable mass for automated systems.

Operational features of the MAC090C-0-KD-4-C/110-B-0/WI531LX include its ability to operate reliably in multi-axis arrays, using friction-locked shaft connections to reduce backlash and improve service life. The plain output shaft interface supports mounting of pinions or belt pulleys via clamping sets, while the optional keyway output shaft conforms to DIN 6885 for precise torque transmission. The absence of an integrated brake reduces mechanical complexity and eliminates potential failure modes under challenging conditions. Designed for continuous and peak-load cycles, this motor maintains performance stability, benefiting from its natural convection cooling and robust electrical windings.

Integration into control systems is straightforward, leveraging the incremental encoder’s standard mounting for compatibility with common servo drives and controllers. The part_number designation ensures accurate matching of motor parameters to drive firmware tables, facilitating rapid commissioning. Target applications include CNC machine tools, robotic actuators, packaging lines, and any system demanding precise torque control and dynamic response. As part of the MAC AC Servo Motors family, this unit embodies Bosch Rexroth Indramat’s commitment to dependable, high-precision automation solutions.
