MAC071A-0-HS-3-C/095-A-0

The MAC071A-0-HS-3-C/095-A-0 from Bosch Rexroth Indramat stands as a robust member of the MAC AC Servo Motors series, engineered for high-performance motion control across diverse automation sectors. This high-torque AC servo motor delivers a continuous output of 2.2 Nm at a nominal speed of 3000 rpm, distinguishing it as a compact yet powerful solution. Weighing 6.5 kg, the unit features a 95 mm centering diameter and a length designation of A, facilitating straightforward mechanical integration. With a thermal time constant of 45 minutes and a peak current pulse rating of 13, it combines responsive dynamic behavior with reliable thermal resilience.

The technical capabilities of this servo motor are underscored by its precise electrical and mechanical design parameters. The winding resistance of 7.6 ohms and winding inductance of 42 mH are optimized for rapid current control and minimal energy loss. A torque constant of 0.860 Nm/A ensures efficient torque generation, while the rotor’s moment of inertia of 5.4 x 10^-4 kgm² contributes to agile acceleration and deceleration profiles. Rated under the AC Servo Motor: MAC designation with Motor Size 71, this unit operates comfortably within an Operating Temperature Range of 0 to +45 °C. The lack of a holding brake simplifies the mechanical design and reduces maintenance requirements.

Operational features emphasize durability and ease of maintenance. An IP65 protection rating and black prime coat (RAL 9005) housing provide full protection against dust ingress and water jets, along with corrosion resistance. The natural convection cooling method leverages ambient airflow for heat dissipation, complemented by integrated thermal switches in the winding and stator housing to prevent overheating damage. The use of Insulation Class F materials ensures excellent dielectric strength and long service life even under continuous duty. The motor’s compact dimensions and reliable thermal management enhance uptime and reduce the need for auxiliary cooling systems.

Integration of the MAC071A model is seamless within existing drive architectures. The power connector on side A and Motor Length: A configuration align with Bosch Rexroth Indramat’s TDM, KDS, and DSC drive controllers, enabling plug-and-play commissioning. With compatibility up to 1,000 meters above sea level, the motor supports applications in machine tools, textile machinery, printing presses, packaging lines, robotic systems, handling equipment, and transfer stations. Proper mounting according to the MAC user manual ensures minimal vibration and optimal performance across industrial automation tasks.
