Product Description:

The MAC071C-0-NS-4-C/095-A-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts ±10 V or current-mode commands from legacy servo amplifiers into controlled rotary motion for pick-and-place axes, feeders, and other precision machine functions. The winding code NS matches the electrical values used with original MAC power stages, so the motor can be paired with compatible amplifiers for stable torque and speed control. Integrated feedback channels let the drive monitor motion continuously during positioning and speed-regulated operation.

The motor reaches a rated speed of 3000 rpm, which suits general automation axes that need a broad operating range without unusually high gearing. Cooling is provided by natural convection, so the housing can shed heat without an external fan when air can circulate freely around the frame. Power conductors enter through a connector on side A, which keeps cable routing on the same face as the usual MAC feedback connection and helps in narrow machine spaces. A centering diameter of 95 mm aligns the flange with mating gearbox or machine surfaces for accurate mounting. The feedback arrangement supports tachometer-based incremental signals or absolute position feedback, depending on the installed interface.

The motor is supplied with no blocking brake, so any load that must remain fixed after power removal needs external holding force. Its motor length code is C, which places it in the medium body length for this platform and gives a balance between torque capacity and rotor inertia. The frame size is 071, which sets the outer motor envelope used across matching MAC variants. A built-in tachometer produces 3 V/1000 rpm for analog speed feedback to compatible controllers. Incremental encoder signals and standard mounting hardware support the position loop and help the drive maintain stable velocity regulation during continuous duty.
