Product Description:

The MAC090B-2-PD-4-C/110-B-0/WI520LV/S001 is manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This electromechanical unit is an AC servo motor intended for analog drive systems, supplying closed-loop torque and velocity in industrial automation. By combining permanent-magnet excitation with wound stator assemblies, the motor converts electrical power into precisely regulated mechanical motion for positioning tables, packaging axes, and other motion tasks. Its closed-loop behavior helps the connected drive maintain consistent motion during changing loads and repeated start-stop cycles.

The motor’s mechanical interface includes a centering diameter of 110 mm, allowing rigid location in flange mounts without additional sleeves. Heat generated in the stator is removed through axial surface cooling, and a frame-mounted blower rated for AC 115 V maintains forced airflow across the housing. That airflow travels along the length of the frame, promoting even temperature distribution on all stator teeth. Under nominal excitation, the rotor reaches 1500 rpm, a speed matched to medium-inertia load requirements in conveyors or gantry axes. The motor uses a PD winding, which provides resistance and inductance values chosen for stable current control in analog amplifiers.

Position and speed feedback use separate devices. A shaft-mounted incremental encoder is fitted for drive commutation, while a tacho generator produces 3 V/1000 rpm with standard quality to deliver analog velocity signals to older regulator cards. This combination supports both commutation and analog speed monitoring in control systems that use traditional regulator hardware. The power terminations exit through a connector on side B, so cabinet wiring can approach from the non-drive end of the machine. The motor is supplied without a blocking brake, making it suitable for horizontally oriented axes where passive holding torque is unnecessary, while vertical applications require an external holding method.
