Product Description:

The MAC090B-0-ND-4-C/110-A-2 is a servo motor in the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is built for integration with analog drive controllers, where rapid torque production and precise speed regulation are required for positioning tables, packaging axes, and material-handling gantries. By pairing a permanent-magnet rotor with electronic commutation, the motor translates command voltages from legacy amplifiers into stable rotary motion suited for continuous or cyclic industrial tasks. Its operating concept suits machinery that uses external analog amplifiers rather than fully integrated digital drives.

A heavy-duty blocking brake is fitted so the shaft can stay locked during power loss or maintenance, eliminating the need for external clamps on vertically oriented loads. The housing features a 110 mm centering diameter that aligns the stator face with gearbox or machine frames while minimizing runout. Cooling relies on natural convection, so the finned exterior dissipates heat into ambient air without forced airflow or liquid jackets. Position feedback is supplied through the specified W/tacho feedback incremental or absolute encoder arrangement, giving velocity and position signals compatible with analog velocity loops. To simplify wiring inside tight cabinets, the three-phase supply enters through a connector on side A, keeping power conductors on the same plane as the brake and feedback plugs.

The control loop benefits from the motor’s standard tacho quality, which maintains signal linearity for stable low-speed regulation. Because it is a motor for analog drives, its back EMF constant and tachometer output are matched to the voltage ranges of legacy drive electronics. As part of the MAC AC Servo Motors series, it is suitable for automation systems that rely on this motor platform. The feedback and brake functions support axes that must hold position at standstill while still delivering repeatable motion during normal cycling.
