Product Description:

The MAC071B-0-TS-4-C/095-A-1/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts commanded current from a drive controller into rotary motion for positioning or velocity-controlled axes in industrial automation. The unit supports synchronized movement in packaging, printing, and material-handling equipment where precise response and repeatability are required. Its design is suitable for applications that need repeatable starts, stops, and speed changes during normal machine operation.

A centering diameter of 95 mm keeps the motor concentric with mounting flanges, which helps minimize shaft misalignment during installation. Operating at a nominal speed of 3000 rpm, it maintains rated output without exceeding thermal limits. The integrated blocking brake provides 3 Nm of static holding torque so vertical loads remain stationary during power loss. Cooling relies on natural convection, eliminating external fans or liquid circuits and keeping the housing free of added cooling hardware. For speed feedback, an internal tacho generates 3 V/1000 min⁻¹, supplying the analog drive with a proportional voltage reference that supports closed-loop speed regulation during acceleration and steady operation.

The 071 frame designation identifies the outer dimensions and shaft height used for medium-duty servomechanisms. Three-phase power is routed through a connector on side A, which helps simplify cable routing along the machine frame. Rotor position is reported by an incremental encoder installed in the standard location, complementing the tacho signal with position data during closed-loop operation. The electromagnetic circuit uses the TS winding code, matching the motor to compatible analog drives. The motor also uses a B-length housing, which gives it the axial length assigned to this frame size.
