Product Description:

The MAC071B-0-FS-4-C/095-B-0/WI518LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts command voltages into precise mechanical motion for positioning tables, pick-and-place mechanisms, and other automated assemblies. By combining tachogenerator feedback with encoder signals, it supports both velocity regulation and accurate positional correction within established control architectures used across industrial automation. Its feedback arrangement allows the paired amplifier to monitor motor behavior during changing loads, which helps maintain stable operation in demanding axis applications.

The motor is built without a blocking brake, so external holding methods are required when power is removed. A centering diameter of 95 mm simplifies coaxial mounting to gearboxes or machine frames. Heat is dissipated through natural convection, eliminating the need for forced-air accessories in sealed cabinets. Size code 071 identifies the stator and rotor geometry, while the nominal shaft speed of 2000 rpm matches the operating range of older drive amplifiers. Winding code FS indicates the copper fill and impedance values that affect current draw and torque output. Standard tacho quality is suitable for velocity loops that tolerate minor ripple. This arrangement supports applications that need dependable motion control without auxiliary cooling hardware.

Mechanical power is transmitted through a DIN 6885 keyway machined into the shaft for secure coupling to pulleys or couplings. The assembly’s physical length is identified by code B, offering medium rotor inertia for balanced acceleration profiles. Mains conductors are routed through a connector on side B, keeping encoder leads on the opposite face to reduce electrical noise. Incremental encoder feedback with standard mounting is the default position reference, and a tacho voltage of 3 V/1000 rpm supplies the drive with proportional speed information. The medium length supports a practical balance between package size and rotating mass for repeated start-and-stop motion.
