Product Description:

The MAC90B-0-PD-4-C/110-B-0/W1522LX is a servo motor produced by Bosch Rexroth Indramat for inclusion in the MAC AC Servo Motors series. Intended for analog drive controllers, it converts electrical current into rotary motion for coordinated positioning tasks in industrial automation cells. The unit is built around a 24 mm keyed shaft and locates to adjoining machine components through a 110 mm centering pilot, ensuring coaxial alignment. Power and feedback connectors are arranged on side B to fit common cabinet layouts and keep cable routing orderly in compact machine assemblies.

During static load conditions, the motor delivers a standstill torque of 7.2 Nm while drawing 11.9 A. This indicates its holding capability when motion is paused. Under rotation, it reaches 2000 rpm, and the windings have a torque constant of 0.67 Nm/A, so current produces proportional mechanical output. For starts or shock loads, the controller may send up to 86 A as a peak pulse to accelerate the rotor. Heat is removed solely by natural convection, so airflow around the housing must remain unobstructed. Rotor position is reported through tacho feedback augmented by a mounted encoder, allowing closed-loop speed and position regulation.

The electromagnetic circuit presents a winding inductance of 5.1 mH and a resistance of 0.97 Ω, which influence current response and copper losses under load. Thermal capacity is expressed by a time constant of 60 min, so internal temperature changes gradually during changing duty. External ingress protection is classified as IP65, which blocks dust and resists water projected from a nozzle during operation. The sealed housing helps protect internal components in areas exposed to airborne debris and routine equipment washdown.
