Product Description:

The MAC90B-0-ID-1-B/110-A-0/JX625/S01 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, it turns voltage or current references into precise rotational motion needed in conveyors, packaging tables, and numerically controlled spindles. The motor has a frame size of 90, giving machine installations a compact source of closed-loop torque without the need for external gear reduction.

Heat is dissipated through natural convection, so the cast housing must remain unobstructed to sustain continuous duty. The enclosure is rated at IP65, preventing airborne dust or water jets from reaching the stator windings during washdown cycles. The output shaft measures 24 mm in diameter and extends 50 mm, making it suitable for standard keyed couplings and timing pulleys. A center spigot thread of M8-19 aids extraction of the motor from tightly fitted adapter plates, while the 110 mm centering diameter aligns the rotor axis concentrically with driven loads. The B5/B14 flange layout offers both through-bolt and face-mount options. All power conductors exit on Side A, minimizing cable loops in right-hand machine frames.

Rotor position is monitored by incremental encoder feedback, enabling analog amplifiers to close position or velocity loops with 1 Vpp sine signals. Operation is permitted up to 1000 m above sea level without derating, making the unit suitable for most plant elevations. A black prime coat in RAL 9005 resists solvents and matches common cabinet hardware. Four mounting holes tapped 4 × M8 × 12 secure the flange to the machine bed. The motor is supplied without an internal blocking brake, so vertical axes must rely on external holding methods. It can be stored between -20 °C and +80 °C without damage to the magnets or bearings.
