Product Description:

The MAC071C-0-NS-4-C/095-A-0WI522LV is a brushless servo motor produced by Bosch Rexroth Indramat for use with analog drive amplifiers in the MAC AC Servo Motors series. The motor translates current commands into precise shaft movement so automated stations can index, clamp, or follow dynamic profiles. Integrated speed feedback keeps the drive aware of rotor motion, allowing tight control loops that are essential in packaging lines, material-handling gantries, and other continuous-duty industrial machines.

The motor centers on a flange with a 95 mm pilot diameter, which helps maintain concentric alignment between the stator housing and the driven gearbox. Heat is removed solely through natural convection, so the housing fins must remain unobstructed by brackets or cable trays. Under rated conditions, the rotor reaches 3000 rpm, a speed chosen to balance torque density with bearing life in medium-inertia loads. A built-in tacho generator produces 3 V/1000 rpm, giving the analog controller a proportional velocity signal for stable closed-loop regulation. Incoming three-phase power is routed through a single connector on side A, so power and feedback wiring leave in the same general direction.

The mechanical envelope follows length code C, and the stator frame uses size 071, giving the motor a compact profile that often fits inside 140 mm square mounting patterns without jack bolts. Electrical characteristics are set by winding code NS, whose resistance and inductance pair with analog drives that supply the required current slope while keeping voltage within insulation limits. The motor has no blocking brake, so position holding during power-off must be handled externally. The feedback system uses tacho feedback with an incremental or absolute encoder, so the drive can receive either coarse tachometer signals or high-resolution position data. Tacho quality is standard, which suits general-purpose motion axes where extremely fine velocity ripple is not critical.
