Product Description:

The MAC071C-0-NS-2-C/095 is an AC servo motor engineered by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts electrical commands from legacy velocity or torque controllers into rotational motion for positioning tables, gantry axes, and packaging mechanisms. By integrating with drive amplifiers and gear stages, it offers a compact electromechanical source of precisely regulated torque that supports high cycle rates in industrial automation lines. Its mechanical interface matches standardized MAC mounting flanges used across the platform.

The motor belongs to frame size 071, a designation that indicates its stator diameter and compatible gearbox adapters. A length class of C extends the active stack so higher continuous torque can be reached without increasing the footprint. Shaft alignment is maintained by a centering diameter of 95 mm, allowing accurate seating in precision bearing plates. Heat is removed solely by natural convection, so airflow around the housing must remain unobstructed to keep winding temperature within permissible limits. Under rated excitation, the rotor turns at 3000 min⁻¹, a nominal speed that balances response time with mechanical life for medium-inertia loads used in printing, textiles, and light assembly.

Speed control stability is achieved through tacho feedback, which generates a proportional signal of 3 V/1000 min⁻¹ to inform analog regulators of actual shaft velocity. The feedback device is standard and is suitable for general-purpose positioning where incremental resolution is not required. Electrical characteristics are tied to winding code NS, which indicates the resistance and inductance values expected by the companion drive. Because the model is classified as a motor for analog drives, its connector pinout follows conventional ±10 V command loops often found in retrofitted machinery. This arrangement provides accurate velocity regulation without auxiliary sensors or forced-air accessories.
