Product Description:

The MAC90C-0-KD-3-C/110-A-0/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it delivers controlled torque and speed to machine axes in industrial automation cells, packaging lines, and handling systems. The unit relies on natural convection for heat removal and is supplied without a blocking brake, so an external holding method is required whenever the shaft must remain locked after power is removed.

At standstill, the motor can supply a continuous torque of 10.4 Nm while drawing a continuous current of 17.0 A. These values represent its thermal limit when the shaft is not moving. Under rated operating conditions, the rotor reaches a nominal speed of 2000 rpm, matching drive controllers that generate the corresponding electrical frequency. Torque production is proportional to armature current, as indicated by a torque constant of 0.68 Nm/A, so the controller can calculate output torque from the commanded current. The motor has a stator inductance of 3.6 mH, which influences current ripple, dynamic response, and DC-link filter sizing.

For short transients, the winding can accept a peak current of 125 A, providing additional current for rapid acceleration of the load and internal rotor. The rotor has an inertia of 53 × 10⁻⁴ kg·m². The housing weighs 23 kg, providing mechanical stiffness for mounted couplings, while the second shaft end supports the tacho feedback device. The motor has a thermal time constant of 60 min, so its temperature rises gradually during cyclic operation. Additional attributes include a phase current rating of 13.9 A, a winding resistance of 0.60 Ω, and a centering diameter of 110 mm for accurate flange seating. The power leads are routed on side A to support direct cable routing toward the control cabinet.
