Product Description:

The MAC071C-0-GS-3-C/095-B-0/S001 is a servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drive systems that require controlled torque and rapid speed changes in industrial automation. The unit uses electromagnetic commutation to rotate its shaft and can be integrated into machine tools, handling modules, or packaging lines. Because a blocking brake is not present, an external mechanical holding device is required if the application demands shaft locking while power is off.

The centering flange is machined to a diameter of 95 mm, allowing precise alignment with gearboxes or mounting plates while limiting radial runout. Frame designation 071 identifies the stator cross section and corresponds to the bolt circle used for mid-power axes in compact assemblies. The axial stack has a length code of C, extending the magnetic path to raise continuous torque without changing the frame width. The rotor can reach a nominal speed of 6000 rpm, allowing rapid velocity changes for tasks such as light tapping or operation of pick-and-place heads. Heat is removed through natural convection, so adequate airflow and sufficient clearance around the motor are important when duty cycles approach the thermal limit.

The motor uses winding code GS, which indicates resistance and inductance values matched to analog drives in the MAC platform. A built-in tacho generator delivers 1.5 V/1000 rpm on the auxiliary shaft, providing speed feedback with standard accuracy for closed-loop regulators. The power connector is oriented toward side B, keeping signal leads clear in installations where the drive cable exits opposite the load coupling. The feedback configuration includes tacho feedback and a second shaft end, allowing an additional encoder or mechanical transducer to be attached without modifying the primary shaft. This arrangement separates the main mechanical output from auxiliary feedback equipment while preserving access to both shaft ends.
