Product Description:

The MAC112B-0-GG-3-F/130-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts drive amplifier commands into controlled rotary motion for positioning tables, packaging axes, and other automated equipment. The integrated blocking brake secures the shaft when power is removed, supporting safety and load-holding requirements common in industrial automation.

The shaft-mounted brake develops 45 Nm of holding torque, enabling vertical loads to remain stationary without external clamps. Accurate mechanical alignment is achieved through a centering flange of 130 mm, which matches standard gearbox interfaces. Cooling relies on natural convection; housing fins dissipate heat without fans or liquid circuits. This passive arrangement reduces the number of moving parts and does not require auxiliary cooling connections. Speed feedback is provided by integrated tacho feedback, supplying an analog velocity signal for legacy controllers. A second shaft end leaves room for a mechanical encoder if needed. This arrangement supports installations that use separate mechanical position sensing in addition to the analog speed signal. Nominal operating speed reaches 3000 rpm, allowing high-throughput cycles with consistent torque across the rated range. Electromagnetic properties follow winding code GG, so current limits and resistance values align with this motor configuration.

The frame corresponds to size 112 with length B, offering a balance between continuous torque and compact envelope dimensions. Power conductors exit through a connector on side B, simplifying right-hand cabinet layouts and separating high-voltage wiring from signal leads. The tacho generator delivers 3 V/1000 rpm, providing a proportional voltage that drives can use for slip monitoring, overspeed detection, or closed-loop speed regulation.
