Product Description:

The MAC071C-0-NS-4-C/095-A-1/WI520LX/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts electrical command signals into precise mechanical motion for automated machinery, where stable speed regulation and repeatable positioning are critical. The feedback arrangement supports tacho feedback, incremental encoder, or absolute encoder signals, which gives the matching drive flexibility in closed-loop control. That makes the motor suitable for feed axes, handling systems, and other applications that depend on accurate response to changing commands.

This motor relies on natural convection to transfer heat from the housing, so it can be mounted without forced-air accessories in compact cabinets. A centering diameter of 95 mm aligns the 071-frame stator with gearboxes or direct-drive flanges, and frame length C provides winding volume suited to continuous duty. The integrated blocking brake delivers 3 Nm of static holding torque to secure vertical axes during power loss. The brake also helps keep the shaft from drifting when the system is stopped. Rated speed capability reaches 3000 rpm, supporting mid-range spindle or feed tasks where moderate inertia must be accelerated quickly. Output torque is transmitted through a shaft finished with a DIN 6885 keyway, allowing standard keyed couplings to handle start-stop or reversing loads without fretting.

Position and velocity data are generated by an internal incremental encoder mounted in the standard location for this series. For systems that require velocity feedback, the commutating tacho generator produces 3 V/1000 rpm, and its tacho quality is standard for general-purpose performance. The stator uses winding code NS, which gives the electrical resistance and inductance expected by the analog drive. Power leads exit through a connector on side A, which keeps the cable bundle on the same face as neighboring motors in multi-axis installations.
