Product Description:

The MAC090C-0-GD-4-C/110-A-1/WI520LX/S001 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is an AC servo motor used with analog drives to provide closed-loop speed and position control in automated machinery such as pick-and-place stations, feeders, and light machining axes. By supplying precise torque in response to drive commands, the unit converts electrical control signals into rotational motion that can be directly coupled to gearboxes or load shafts. This supports repeatable motion in equipment that must start, stop, and reverse direction with stable control.

A centering diameter of 110 mm lets the motor seat accurately in machine frames, maintaining coaxial alignment with the driven shaft. Heat produced by the stator is removed through natural convection, eliminating the need for external blowers and keeping enclosure requirements simple. The stator uses winding code GD, which allows compatible analog drives to be tuned predictably. Power conductors enter through a connector on side A, which routes the cable away from moving parts on the opposite face. Rotor position is reported by an incremental encoder with standard mounting, and this encoder produces uniformly spaced pulses that analog velocity and position loops can process directly.

A standard blocking brake holds the shaft when power is removed, preventing vertical or suspended loads from drifting. The unit is classified as a motor for analog drives, meaning its electrical interface is matched to drive cards that generate continuous-time current commands rather than fieldbus packets. For applications that need both velocity and absolute position data, the feedback configuration supports tacho feedback with an incremental or absolute encoder, allowing higher-resolution feedback devices without mechanical changes. Speed monitoring accuracy is supported by the standard tacho quality rating, which indicates ripple limits of the built-in tachometer and helps maintain stable velocity regulation during fine positioning tasks.
