Product Description:

The MAC112D-0-ED-2-C/130-B-1 is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts electrical energy into controlled rotary motion for positioning and speed-control tasks in industrial automation. This frame size is frequently used on gantry stages, indexing tables, and packaging axes where consistent torque and moderate inertia are required. It interfaces with legacy MAC drive amplifiers through analog current commands, which keeps it suitable for systems built around voltage-based control loops.

The integrated blocking brake supplies 45 Nm of holding torque, so vertical or suspended axes remain stationary when power is removed. Thermal management depends on natural convection, so the housing must remain unobstructed to let heat rise away from the stator. During continuous operation, the shaft turns at a nominal speed of 3000 rpm, matching drive amplifiers that regulate velocity through analog command voltages. A centering pilot of 130 mm locates the motor precisely on machine frames, while length code D indicates the magnetic stack depth used for this 112-frame unit.

The tachogenerator delivers a velocity signal of 3 V/1000 rpm, allowing the controller to close a proportional speed loop without additional sensors. Its performance matches winding code ED, so the generated voltage and phase resistance suit the characteristics expected by legacy MAC amplifiers. Power conductors exit through a connector on side B, which can simplify cable entry when the cabinet is mounted on the opposite side of the machine. The use of tacho feedback instead of a digital encoder keeps the motor compatible with earlier analog control architectures that rely on speed-related voltage signals.
