MAC090B-0-PD-4-C/110-B-0/WA612XX/S001

The Bosch Rexroth Indramat MAC090B-0-PD-4-C/110-B-0/WA612XX/S001 from the MAC AC Servo Motors series is a high-performance permanent magnet AC servo motor designed for precision automation. It features a compact Motor Size 90 frame with a Motor Length B design and a robust Power Connection Side B interface. Cooling is managed by Natural Convection, delivering quiet operation and minimal maintenance requirements. The motor’s permanent magnet rotor maintains exceptionally low inertia for rapid acceleration and accurate speed control.

The winding assembly exhibits a resistance of 0.97 Ω and an inductance of 5.1 mH at 20 °C, supporting fine-tuned current regulation up to a nominal speed of 2000 min⁻¹. Feedback is provided by a factory-mounted B-type encoder, while a standard tacho output of 3 V/1000 min⁻¹ ensures reliable speed sensing. The shaft centerline is configured for a centering diameter of 110 mm in B05 and B14 housings, and the Blocking Brake is Not Equipped, simplifying integration where braking torque is not required. Despite its precision design, the motor withstands demanding duty cycles without derating.

Boasting a mass of 18 kg and housed in a rugged metal enclosure, this AC servo motor endures corrosive, explosive, and mining atmospheres with ease. The output shaft is plain-ground and keyed per DIN 6885 slot 1, 8/68 edition, ensuring secure coupling to loads. Optional encoder connectors and the INS 108 power connector must be ordered separately to complete installation in specialized drives and control cabinets.
