Product Description:

The MAC090B-1-JD-1-B/110-B-0/J625 is an AC servo motor produced by Bosch Rexroth Indramat. It converts drive-controller command voltages into controlled rotational motion for positioning and speed-control tasks in industrial automation. The unit’s mechanical interface, electrical feedback, and cooling method are arranged for use in legacy machine tools and material-handling axes. It is suited to systems that rely on analog command inputs rather than integrated digital communication. In these applications, the amplifier handles the control loops while the motor supplies the rotary output. Its frame size and connector orientation match earlier MAC models used in existing machine layouts.

This model relies on an external blower that runs at AC 230 V to push air along the housing fins. The forced airflow provides axial surface cooling, which helps maintain continuous torque without excessive winding temperature rise. A machined 110 mm centering diameter aligns the front flange with gearboxes or mounting plates and helps keep the shaft concentric during installation. Position data is returned through incremental encoder feedback, providing pulse signals that the connected drive can use for speed and position control. Power conductors terminate on a connector on side B, which helps route cabling away from the shaft and coupling area in tight enclosures.

The motor operates without a blocking brake, so external holding functions must be provided when the axis is stopped. Any load that must remain fixed at standstill requires holding force from the machine design or the connected drive. The absence of an internal brake reduces inertia and avoids brake-related wear components inside the motor. It follows the frame and winding conventions used across the MAC AC Servo Motors range, which supports installation in existing MAC machine layouts. When paired with an analog drive controller, the unit uses standard ±10 V command signals for closed-loop motion.
