MAC071C-0-JS-4-C/095-A-2/MR136

The MAC071C-0-JS-4-C/095-A-2/MR136 from Bosch Rexroth Indramat is a high-performance unit within the MAC AC Servo Motors series, engineered for demanding industrial automation applications. This AC servo motor operates on a 230 V input voltage and delivers a nominal speed of 4000 rpm under a rated load of 2 HP. Featuring a compact Motor Size 71 and a streamlined Motor Length C, the motor’s sleek form factor facilitates integration in space-constrained environments. Built to Insulation Class F standards, the MAC071C-0-JS-4-C/095-A-2/MR136 offers robust durability and consistent performance even in elevated ambient temperatures.

Technical capabilities of this servo motor are exemplified by its precise electrical and mechanical characteristics. The Torque Constant at 20 °C of 0.430 Nm/A ensures efficient torque generation and responsive control, while the Winding Resistance at 20 °C of 0.35 Ω minimizes heat generation and energy losses. Engineered as a Frequency Inverter Drive type, the motor harnesses a 3-phase configuration and supports a Max Pulse Current of 77 A for transient overdrive capacity. The rotor features a Rotor Moment of Inertia (w/ tachogenerator, no brake) of 12.9 x 10^-4 kg·m², promoting stable acceleration and deceleration profiles. Cooling is achieved through Natural Convection, which reduces maintenance complexity and supports continuous operation without external fans.

Operational features emphasize reliability, efficiency, and precision in motion control systems. The MAC071C motor’s low winding resistance and high torque constant combination delivers smooth torque output and minimizes thermal buildup under sustained loads. Natural convection cooling allows for silent operation and reduces the risk of particulate contamination associated with forced-air cooling solutions. The compact dimensions of the Motor Size 71 and Motor Length C facilitate easy mounting and alignment in modular machine frames. With its advanced frequency inverter drive compatibility, this servo motor provides tight speed regulation and rapid torque response, ensuring superior positioning accuracy and repeatability across diverse process cycles.

Integration and application versatility make the MAC071C-0-JS-4-C/095-A-2/MR136 ideal for modern automated systems. Seamless interfacing with Bosch Rexroth drives and controllers simplifies commissioning and parameter tuning through electronic nameplate recognition. The motor’s performance envelope supports use in CNC machinery, packaging lines, robotic manipulators, and other precision motion platforms where dynamic response and compact design are essential. By combining rugged construction, high thermal resilience, and precise control characteristics, this AC servo motor delivers a reliable foundation for scalable industrial automation solutions.
