Product Description:

The MAC071C-0-JS-4-C/095-A-1/WI504LV/S001 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts current-loop commands into controlled torque and speed for machine-tool, packaging, and material-handling axes. When paired with legacy drive amplifiers, the unit provides closed-loop motion capability in industrial automation where positional accuracy, repeatability, and stable velocity are required during repeated indexing and feed movements.

The 071 frame and C-length stator give this motor a compact form factor while supplying the continuous power expected in mid-range feed axes. A concentric mounting pilot of 95 mm centers the housing on the machine plate, and the shaft includes a blocking brake able to deliver 3 Nm of holding torque when the axis is idle. Thermal energy is removed through natural convection, so the motor can be installed without external cooling hardware. Under rated field excitation, the rotor reaches a mechanical speed of 2000 rpm, allowing direct coupling to ballscrews or timing pulleys driven by analog velocity loops. Tachofeedback is available, and the generator produces 3 V/1000 rpm, supplying a proportional velocity signal to the drive for fine speed regulation.

Position reference signals are supplied by the integrated incremental encoder with standard mounting, supporting reliable commutation and referenced homing. The winding code JS sets the phase resistance and back-EMF constants expected by the matching drive, which helps the amplifier regulate motor current correctly across normal operating ranges. Mechanical power is transferred through a shaft with a DIN 6885 keyway, simplifying coupler installation. For wiring, the three-phase power leads exit through a connector on side A, which helps keep cable routing direct inside typical right-mounted control cabinets and reduces interference with adjacent machine hardware.
