Product Description:

The MAC092B-0-QD-4-C/095-B-1/WI574LV/S001 is an AC servo motor in the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Intended for closed-loop motion axes, it converts analog command voltages into controlled rotary output that positions indexing tables, feeder rolls, and assembly tooling on automated lines. Integrated electromagnetic design lets it deliver torque with low speed ripple, while internal sensors provide feedback to the external amplifier. This makes the unit a direct mechanical actuator for legacy and retrofit platforms that still rely on analog servo technology.

Mechanical interface, thermal behavior, and cabling are important installation factors. A centering flange of 95 mm aligns the stator housing with gearboxes or machine frames, keeping shaft runout within tolerance. Heat is dissipated by natural convection, so the motor can operate in cabinets that have only free-air circulation. The three-phase supply enters through a connector on side B, allowing the cable to be routed away from moving links or guards. An internally fitted blocking brake clamps the rotor when the amplifier is disabled, preventing axis drift during maintenance or emergency stops.

Feedback components secure velocity and position control. The feedback cavity accepts a tacho feedback, incremental encoder, or absolute encoder, supplying either speed voltage or digital position data to the drive electronics. The primary sensor shipped with this model is an incremental encoder with standard mounting, which simplifies mechanical alignment during installation. Closed-loop stiffness is supported by standard tacho quality, which provides repeatable feedback voltage across the full speed range. As a motor for analog drives, it connects directly to ±10 V command amplifiers commonly retained in brownfield installations where existing diagnostic tools and parameter sets are already established.
