Product Description:

The MAC090B-0-ND-2-C/110-B-0/S005 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for closed-loop motion control, it interfaces with analog servo amplifiers to drive machine axes in packaging lines, transfer stations, and metal-cutting equipment. By converting electrical command signals into rotational movement with high positional accuracy, the unit provides the actuating element that maintains speed stability and repeatable positioning in automated industrial processes. This operating role makes it suitable for equipment that depends on smooth acceleration, stable running speed, and repeatable stopping points during continuous cycles.

The mechanical interface includes a centering recess of 110 mm, which aligns the stator housing with mounting brackets and helps maintain concentricity between the motor and load shafts. Thermal management relies on natural convection, so heat is dissipated through the ribbed frame without auxiliary fans or liquid circuits. Position and velocity signals are generated by a built-in tacho generator, and the drive electronics receive this feedback through tacho feedback, supporting analog speed loops with millisecond response. Power conductors exit through a connector on side B, which can simplify cable routing when the motor flange faces the machine frame. This layout helps the motor fit machine assemblies that use the same mounting pattern and cable direction across multiple axes.

The model is supplied without a blocking brake, so holding torque during power-off conditions must be provided by external clamping or by the drive itself. Its tacho generator follows a standard tacho quality classification, offering the signal quality expected by legacy controllers without requiring recalibration. Because it is specified as a motor for analog drives, the winding constants and feedback voltage levels are matched to ±10 V command signals rather than modern digital buses. That arrangement suits machines that continue to use analog amplifiers and conventional feedback loops in long-service automation cells.
