Product Description:

The MAC092B-0-QD-2-C/095-B-0 is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. The unit supplies controlled torque and speed for closed-loop motion axes in packaging lines, material-handling stations, and similar automated equipment. Its mechanical interface allows direct coupling to gearboxes or belt transmissions where precise velocity regulation is required. The motor converts proportional current commands from a compatible drive amplifier into smooth rotary motion while returning speed information to the control loop. This arrangement helps the connected drive compensate for changes in load during acceleration, steady operation, and deceleration.

The centering boss is machined to 95 mm, providing a fixed reference diameter for repeatable alignment against mounting plates. Heat from the stator is removed by natural convection, so the surrounding installation must allow unrestricted airflow around the housing. The motor has no blocking brake, which means any required holding force during a power loss must be supplied by the drive or an external clamp. Speed information is delivered through tachometer feedback, which produces an analog voltage proportional to shaft rotation for the velocity control loop. Power conductors attach through a connector on side B, allowing cables to be routed away from moving machine components. Careful alignment of the centering boss helps reduce coupling stress and supports stable shaft rotation after installation.

As a motor for analog drives, the stator windings accept proportional current commands from legacy amplifier cards rather than digital network commands. The standard tachometer provides the linear response needed by conventional proportional-integral regulators without requiring a separate speed sensor. A frame size of 092 provides a moderate mechanical envelope for general-purpose automation axes with limited mounting space. The B-length housing accommodates the QD winding arrangement while retaining the mounting proportions associated with this motor platform. Keyed circular connections help prevent incorrect plug orientation, and established conductor color coding supports clear power and feedback wiring. The passive thermal design also avoids fan components that could introduce additional wiring, vibration, or periodic maintenance requirements.
