Product Description:

The MAC90C-0-GD-2-C/110-A-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts drive current into controlled mechanical motion for indexing tables, pick-and-place arms, and other precision axes. The frame is machined with a 110 mm centering diameter for accurate mounting, and the cable glands accept power conductors with a cross-sectional area as small as 2.5 mm², allowing the motor to integrate into compact cabinets.

The unit delivers a nominal rotor speed of 3000 rpm, allowing direct coupling to gearboxes or belt drives without overspeeding standard machine components. At stall, it can supply 9.6 Nm of continuous torque while drawing 24.8 A; this pairing represents the steady-state operating point at which copper losses and temperature rise remain within design limits. For fast acceleration, the drive may apply a peak pulse of 196 A, allowing the motor to overcome inertial loads without requiring oversized hardware. The motor has a torque constant of 0.43 Nm/A and a winding inductance of 1.5 mH, and both parameters influence current-loop tuning in the controller.

The housing meets IP65, protecting the windings and bearings against airborne dust and water jets encountered on processing floors. Heat absorbed during continuous operation dissipates slowly, as indicated by a thermal time constant of 60 min; drive parameters can therefore permit short overloads without immediate temperature alarms. With a mass of 23 kg and a rotor inertia of 53 × 10⁻⁴ kg·m², the motor stores enough energy for smooth velocity regulation while remaining light enough for cantilevered mounting. A phase current rating of 20.2 A and a winding resistance of 0.24 Ω provide additional electrical data for matching the motor with compatible legacy analog amplifiers.
