Product Description:

The MAC90B-0-ID-1-B-110-A-1/J1250/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it provides closed-loop speed and position control in packaging machinery, material-handling axes, and other industrial automation systems. Natural convection removes heat from the stator without requiring forced-air accessories. The winding, shaft, and flange geometry use a 110 mm centering diameter and a 50 mm shaft extension to accommodate common gearheads and couplings.

The electromagnetic holding brake develops 6.5 Nm of torque to keep the load stationary whenever the drive disables torque production. Its coil operates from a 24 VDC supply and draws 0.7 A, allowing the brake to use a standard control power bus. When commanded, the brake clamps the shaft within 20 ms, while its release time is 60 ms. These response times must be considered in motion sequences that alternate between static holding and dynamic travel. The power connection exits on side A for direct cable routing inside the control cabinet. A center spigot with an M8-19 thread supports accurate alignment during mounting.

The brake rotor adds an inertia of 1.06 × 10⁻⁴ kg·m², which must be included in axis tuning calculations but still permits responsive acceleration due to the motor’s compact mass. The brake has a mass of 0.5 kg, adding a modest load to the overall assembly. An IP65 housing seals the stator against dust and water jets, allowing installation near process equipment without an additional enclosure. Mechanical output passes through a shaft with a diameter of 24 k6, providing a controlled fit for compatible couplings. The motor can operate at elevations up to 1000 m above sea level without derating, provided the remaining operating conditions stay within the permitted limits.
