Product Description:

The MAC090B-0-PD-2-C/110-L-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for legacy analog motion loops, this unit converts current commands from drive amplifiers into controlled shaft rotation that positions packaging axes, gantry slides, and material-handling equipment. Integrated tachogenerator feedback supplies the velocity signal required by these analog controllers, allowing precise speed regulation without a separate encoder.

The motor seats against machinery through a centering pilot of 110 mm, ensuring coaxial alignment with gearboxes or couplings. Stator heat leaves the housing through natural convection, so the installation must permit unobstructed ambient airflow rather than depend on an external fan. The unit comes with tachometer feedback; the built-in tachogenerator produces an analog voltage proportional to rotational speed for immediate use by a drive card. Continuous operation is specified at 1500 rpm, a base speed that balances torque output and thermal loading. Because the motor is delivered without a blocking brake, a mechanical clamp or another external holding device must secure the shaft when power is removed.

The tachogenerator delivers 3 V/1000 rpm, giving the drive a linear gain of 0.003 V per rpm for straightforward loop adjustment. Electrical behavior follows winding designation PD, matching the resistance and back-EMF profile expected by Bosch Rexroth analog amplifiers of the same class. Classified as a motor for analog drives, the unit has insulation clearances and connector pinouts suited to ±10 V command environments rather than digital fieldbus systems. Power conductors exit through a connector on the left side, simplifying cable routing when multiple motors are arranged along a common panel. The tachogenerator uses a standard quality grade, keeping feedback drift within the accuracy limits required for analog control loops.
