Product Description:

The MAC090B-0-JD-1-B/110-A-1-101250 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts drive commands into precise rotary motion for industrial automation axes that require stable speed and torque control. The motor includes incremental encoder feedback so the connected drive can monitor position and speed during operation. It also uses a standard blocking brake to hold the load when power is removed. This arrangement suits packaging, printing, and material-handling equipment where repeatable starts, stops, and speed changes are important.

The motor reaches a nominal speed of 3000 rpm and provides a continuous standstill torque of 6.7 Nm from a sustained current of 18.2 A. For short acceleration demands, it can draw a peak pulse current of 137 A. The housing is rated IP65, which helps keep dust and low-pressure water jets away from internal components. A 110 mm centering diameter aligns the flange, while a 24 mm shaft with a 50 mm extension transfers torque to the driven mechanism. Winding resistance is 0.38 Ω, inductance is 2.0 mH, power is connected on side A, and cooling is handled by natural convection. These electrical characteristics help the paired drive regulate current smoothly during changing load conditions.

A rotor inertia of 0.0036 kg·m² supports responsive acceleration while helping the axis remain stable during speed changes. The torque constant of 0.41 Nm/A gives the drive a straightforward current-to-torque relationship during control. The motor weighs 18 kg, and the incremental encoder supplies position data for closed-loop operation with compatible analog controllers. It can operate at elevations up to 1000 m without derating, which supports installation in a wide range of industrial environments. The inertia and torque constant are useful when estimating axis response in systems that alternate between dwell periods and short bursts of motion.
