Product Description:

The MAC090B-0-ND-3-C/110-A-0 is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for closed-loop motion axes, it transforms drive current into controlled torque and rotational speed so that packaging lines, handling robots, and transfer stations can achieve repeatable positioning. Its cast housing and matched rotor support medium-frame loads while maintaining the mounting geometry commonly used in modular machine layouts. The motor also works with Indramat analog amplifiers, allowing velocity and position control without requiring digital network interfaces.

The mechanical interface is centered by a pilot diameter of 110 mm, which helps maintain coaxial alignment with gearboxes or mounting flanges. Heat generated during operation leaves the frame by natural convection, so airflow around the ribs should remain unobstructed during use. Incoming power is routed through a connector on side A, which fixes cable direction and supports orderly strain relief. The motor has no holding brake, so static load retention must rely on an external brake or the drive’s torque mode when power is removed. Speed information is generated by tacho feedback, and this analog signal feeds the servo controller for continuous velocity regulation.

A rear-mounted second shaft end provides a place to attach auxiliary encoders, fans, or other low-inertia devices without disturbing the primary coupling. Because the unit is supplied as a motor for analog drives, its tachometer voltage can be processed directly by legacy amplifiers that do not use digital feedback loops. The internal sensor is built to standard tacho quality, giving suitable linearity for mid-resolution speed and position control in packaging, printing, and material-feed axes. This arrangement also supports applications where a simple external monitoring device must be added at the rear of the motor.
