Product Description:

The MAC112D-1-ED-4-C/180-A-0/WI517LV/S011 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for rotary axes driven by analog amplifiers, where stable torque production and smooth speed regulation are needed for packaging lines, pick-and-place gantries, and metal-cutting spindles. This type of application often requires accurate response during repeated starts, stops, and speed changes. The size 112 frame with D-length construction gives the motor a substantial active length without changing the basic mounting style used across this platform. The motor has no blocking brake, so any holding function at standstill must be provided by external hardware or by the drive system.

The external blower operates on AC 230 V and provides forced air to the fins that form the motor’s axial surface cooling path. This airflow helps the stator shed heat during sustained operation, which supports continuous-duty use on machines that cycle frequently or run for long periods. Precise centering at the machine interface is provided by a 180 mm pilot diameter, helping the flange seat accurately during installation. Rated mechanical output is reached at 3000 rpm, and position information is supplied by an incremental encoder with standard mounting so the drive receives pulse feedback for velocity monitoring, commutation, and closed-loop control.

Power conductors exit through a connector on side A, which can simplify cable routing when several axes are mounted close together. The solid shaft uses a DIN 6885 keyway, allowing keyed couplings or pulleys to transfer torque without relying on a clamping hub alone. An attached tacho generator produces 3 V/1000 rpm for analog speed feedback, which supports legacy amplifier systems that expect a proportional voltage signal. The stator uses the ED winding code, matching the electrical characteristics of compatible MAC drive modules and supporting predictable current and back-EMF behavior under normal thermal loading.
