Product Description:

The MAC071A-0-OS-4-C/095-B-1/WI517LV is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts command voltages into regulated torque and speed for precise axis control in pick-and-place stations, machine tools, and conveyor modules. This arrangement supports smooth starts, controlled stops, and dependable response when load conditions change. It is well suited for machinery that must move quickly between repeated points without sacrificing control stability.

With a centering diameter of 95 mm, the housing aligns directly to standard mounting flanges and helps reduce radial runout during installation. Cooling relies on natural convection, so heat is dissipated through the surface without forced airflow, which suits cabinets that do not include fan assemblies. A blocking brake is fitted as standard and can hold up to 3 Nm of static load, helping prevent backdriving on vertical axes when power is removed. The rotor and stator geometry correspond to motor size 071, and the shaft reaches 3000 rpm under rated excitation. The A-length frame keeps mass low while still providing the winding volume required for this motor size.

Electrical terminations are routed through a power connector on side B, which simplifies cable runs when the motor is mounted against bulkheads. Winding code OS identifies the coil resistance and inductance used with compatible analog amplifiers. Speed feedback is supplied by a tacho generator that produces 3 V/1000 rpm, while the encoder provides position data through the standard mounting arrangement. Using separate speed and position signals allows the connected controller to monitor axis behavior more closely during acceleration and hold phases. The tacho and encoder follow standard quality grades, supporting repeatable speed regulation across the duty range and accurate response during indexing and synchronization.
