Product Description:

The MAC092B-0-QD-1-B/095-B-0-I01250 is an AC servo motor built by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. The device is intended for analog drives, so it integrates with current-controlled amplifiers that issue analog reference signals rather than digital commands. In discrete manufacturing cells, it supplies closed-loop rotary motion to positioning tables, feed rolls, and similar axes where stable speed regulation and instantaneous torque response are critical.

Several key figures describe the motor's mechanical fit and electromagnetic output. A continuous shaft torque of 3.0 Nm allows the axis to maintain load without overheating during uninterrupted duty. The mounting pilot has a centering diameter of 95 mm, giving alignment support for coupling fixtures and gearbox faces. Heat is removed solely through natural convection, eliminating the need for forced air or liquid circuits but requiring free airflow around the frame. Position feedback comes from an incremental encoder that furnishes 1250 lines per revolution, enabling drive controllers to resolve 5,000 counts after quadrature decoding for finer velocity regulation. For speed monitoring, the built-in tacho generator produces an electromotive force of 0.0143 Vs/rad, permitting analog drives to derive proportional speed signals without external sensors.

The motor has an enclosure rating of IP65, which seals the stator against dust and low-pressure water jets for use in unfiltered cabinet or machine-mount locations. Operation is permitted at ambient temperatures up to +45 °C and installation altitudes that do not exceed 1000 m above sea level, beyond which derating would be required. Power conductors enter through a connector on side B, while signal leads from the encoder exit separately to help reduce electrical noise. The unit is supplied without a blocking brake, so any static holding must be managed by external mechanical locks or the drive's torque-holding capability.
