Product Description:

The MAC071C-0-NS-2-C/095-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for integration with analog drives, the unit converts electrical commands into controlled mechanical rotation for industrial automation axes that demand repeatable velocity and position. The motor forms part of closed-loop systems where a built-in tacho generator supplies real-time speed information to the drive controller, allowing consistent motion under variable process loads. Its construction follows the frame and mounting dimensions used for the 071 family, allowing it to fit existing machine platforms.

The thermal design relies on natural convection, eliminating the need for external blowers and allowing installation in cabinets with limited airflow. Under rated excitation, the rotor turns at 3000 rpm, a nominal speed suited to medium-inertia loads commonly found in pick-and-place gantries. Shaft alignment in the machine frame is aided by a centering diameter of 95 mm. The motor uses motor length C, which provides the active iron volume for continuous torque. It also uses motor size 071, which corresponds to the flange pattern and bolt circle for this frame. No blocking brake is fitted, so holding torque must be supplied by the drive or external mechanics when the axis is idle.

Velocity feedback is generated by an internal tacho generator; this model is equipped with standard tacho feedback, and its power terminals are arranged through a connector on side A for straightforward wiring inside the enclosure. The generator produces 3 V/1000 rpm, giving the drive a proportional voltage signal that scales linearly with shaft speed. The stator coils use winding code NS, which matches the resistance and inductance values expected by compatible MAC servo amplifiers. The feedback signal is used by the drive for speed regulation during operation.
