Product Description:

The MAC090B-0-JD-3-C/110-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is built to operate with analog drive controllers where precise velocity and torque regulation are required on automated production lines, material-handling modules, and packaging axes. By translating command voltages from the drive into rotor movement, the unit provides closed-loop position and speed control that supports repeatable motion sequences in industrial machinery. This arrangement makes the motor suitable for machines that depend on stable response during repeated starts, stops, and speed changes.

The motor is positioned by a centering pilot of 110 mm, ensuring the flange seats accurately and the shaft remains concentric with the load. Heat from the windings is removed through natural convection, so no external blower or liquid circuit is required. Power conductors enter through a connector on side A, which simplifies cable routing where space on the opposite face is limited. Rotary feedback is provided by tachofeedback and a second shaft end, allowing simultaneous speed monitoring and the coupling of an additional transducer or brake disk. A standard blocking brake holds the rotor when power is off to prevent back-driving.

This model is supplied as a motor for analog drives, so its armature current and tachometer voltage interface directly with servo amplifiers that use ±10 V command loops. The speed sensor meets a standard tacho quality classification, giving predictable gain and offset values during operation. The analog interface supports controllers that use direct voltage commands for speed regulation. This also helps it integrate with legacy analog motion systems that are still used in established production equipment. The family layout keeps mechanical dimensions and winding codes consistent across related motors.
