Product Description:

The MAC071C-0-US-3-C/095-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it translates amplifier commands into precise rotary motion for positioning or speed-regulated duties in industrial automation. A standard blocking brake is integrated to secure the load at standstill, which makes the unit suitable for packaging, printing, and material-handling equipment that require accurate stops and controlled restarts. The motor is intended for axis applications where repeatable motion and stable feedback are important during routine operation.

Rated holding capacity is provided by a brake torque of 3 Nm, allowing the shaft to resist moderate static forces when de-energized. Thermal management relies on natural convection, which removes the need for fans or liquid circuits. During continuous duty, the rotor operates at a nominal speed of 2000 rpm, a value matched to analog velocity controllers in the same product family. Power enters through a connector on side B, which helps keep cable routing straightforward along the machine frame. For speed feedback, the built-in tacho generator outputs 3 V/1000 rpm, giving the drive a linear voltage signal for closed-loop regulation. This arrangement supports stable speed monitoring without requiring a separate external feedback source for basic analog control.

A centering pilot of 95 mm aligns the motor flange with gearboxes or machine frames to maintain concentricity. The 071 size code corresponds to the stator diameter used in this frame, while the C length code indicates a longer active magnetic stack for continuous torque output. Electrical behavior is set by winding code US, which provides resistance and inductance values suited to matching analog amplifiers. Standard tacho feedback and a second shaft end allow the attachment of additional feedback devices or external mechanical elements when required by the machine layout. This layout gives the motor added flexibility in systems that need both braking support and auxiliary shaft-driven components.
