Product Description:

The MAC090B-0-PD-4-C/110-B-0/W1520LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. In motion-control installations, it converts electrical power into controlled rotary motion so position, velocity, and torque can be regulated by an analog drive amplifier. Its compact frame allows the motor to drive indexing tables, conveyors, and packaging axes that demand repeatable mid-range speed without adding external gear reduction. The motor is also suited to retrofit axes that still rely on external drive electronics rather than integrated digital control.

A centering diameter of 110 mm lets the housing align precisely against a pilot recess on the machine frame, which helps minimize radial runout. Heat is removed by natural convection, so airflow around the fins must remain unobstructed when the motor operates at its nominal speed of 1500 rpm. The copper distribution identified by the PD winding code provides the voltage constant needed by the analog drive and supports the continuous current limit. For speed feedback, the built-in tacho generator provides 3 V/1000 rpm, giving the controller a proportional voltage for closed-loop regulation. Power enters through a connector on side B, which keeps cabling away from the drive-end shaft and helps routing in tight enclosures.

The motor uses tacho feedback with an incremental or absolute encoder, allowing the same mechanical platform to serve either velocity-only loops or high-resolution positioning tasks. Because it ships without a blocking brake, holding torque during power-off must be supplied by an external brake or by a drive that can maintain servo lock. Its classification as a motor for analog drives ensures electrical compatibility with legacy Rexroth controller families that issue ±10 V speed commands instead of modern fieldbus protocols. This arrangement supports upgrades where existing machine wiring and interface hardware remain in service.
