Product Description:

The MAC063B-0-GS-4-C/095-B-0/WI504LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it delivers regulated torque and speed in automation cells that use ±10 V command amplifiers. Typical applications include indexing stations, pick-and-place heads, and small machining spindles that require accurate motion under changing loads.

The mechanical interface has a centering diameter of 95 mm, allowing direct flange alignment with gearboxes or machine frames, while the shaft carries a DIN 6885 keyway for positive torque transmission. The motor reaches a nominal speed of 3500 rpm under its rated electrical load. Heat is removed through natural convection, so no external blower or liquid cooling loop is required. This cooling method reduces the number of auxiliary components needed around the motor and permits installation where fan maintenance would be inconvenient. Speed feedback for the analog regulator comes from an internal tacho generator that produces 1.5 V/1000 rpm, giving the controller a proportional voltage for closed-loop velocity control.

The secondary feedback channel is an incremental encoder mounted in the standard rear housing, supplying digital position data for drives that combine analog speed loops with fine position capture. Power conductors exit through a sealed connector on side B, a layout that keeps cable runs short when the motor is seated against the opposite machine wall. The motor has frame size 063 and a B-length housing, balancing inertia against continuous torque in compact axes. Because the motor has no blocking brake, vertical or suspended loads must be held by external means when power is removed. The stator carries the GS winding code to match its electrical constants with compatible analog amplifiers. The tacho generator uses the standard quality class, supporting consistent speed-signal calibration within the motor series.
