Product Description:

The MAC090B-0-JD-1-B/110-A-0-I00625/S001 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Supplied as a motor for analog drives, it generates controlled rotary motion for position or velocity loops in automated equipment such as packaging axes, material-handling gantries, and indexing tables. The stator and rotor construction allows a drive controller to regulate current and deliver precise torque for closed-loop industrial automation. Because the motor is intended for analog drives, the connected amplifier handles the control loops externally while the motor provides the electromechanical output needed for stable motion.

The motor has a centering shoulder diameter of 110 mm, enabling accurate alignment with gearboxes or frames. At standstill it delivers 6.7 Nm continuously with natural convection cooling. Nominal operation reaches 3000 rpm, providing a common operating speed for servo applications. The controller supplies 14.8 A per phase during rated motion, whereas 18.2 A flows when the shaft is locked. With a torque constant of 0.41 Nm/A, each ampere of stator current produces predictable torque, and the winding resistance of 0.38 Ω contributes to copper losses during operation. The three-phase winding also has 2.0 mH of inductance, which helps limit current rise during acceleration and speed changes.

During acceleration the drive can supply a peak pulse of 137 A, and the rotor inertia of 36 × 10⁻⁴ kg·m² helps the axis respond smoothly to speed changes. An enclosure rating of IP65 protects the windings from dust and water. This suits enclosed machine sections where splashed fluid and airborne debris may be present around moving components. The thermal time constant is 60 min, allowing short overload periods before heat fully builds in the motor. Incremental encoder feedback returns position to the analog controller, and the motor includes no blocking brake, so external holding is required on vertical axes. The 18 kg mass adds damping, and power exits on side A through a sealed connector that keeps cable routing straightforward.
