MAC071C-0-US-4-C/095-A-0/WI589LX

The Bosch Rexroth Indramat MAC071C-0-US-4-C/095-A-0/WI589LX from the MAC AC Servo Motors series is a versatile AC servo motor with a motor size 71 frame and motor length C profile. Designed for precision applications, it features natural convection cooling and weighs just 11 kg, making it adaptable to compact installations. Integrated B05/B14 compatible mounting options simplify mechanical integration into existing systems. A robust side-A power connector streamlines wiring, and the encoder-ready design supports both incremental and absolute feedback.

Engineered for dynamic performance, this motor delivers a continuous current at standstill of 7.3 A (11.8 A peak intermittent) and generates a continuous torque at standstill of 6.6 to 9.9 Nm for reliable hold capacity. The maximum peak pulse current of 37 A ensures ample headroom for rapid torque demands, while a torque constant of 0.900 Nm/A at 20 °C provides efficient electromechanical conversion. The windings resistance at 20 °C of 1.6 Ω and windings inductance of 15 mH are optimized for stable current control, and a rotor moment of inertia of 12.9 x 10^-4 kg·m^2 balances responsiveness with smooth motion. Thermal management is handled by natural convection with a thermal time constant of 45 min, allowing extended operation without performance drift.

This motor’s precise incremental encoder interface and optional absolute feedback deliver high-resolution position data for demanding control loops. The absence of an onboard blocking brake reduces complexity and maintenance points, while the standardized electrical and mechanical interfaces shorten installation time. Combined with Bosch Rexroth Indramat’s legacy of quality, the MAC071C-0-US-4-C/095-A-0/WI589LX is an ideal solution for feedback-driven automation tasks that require consistent torque, rapid response, and effortless integration.
