Product Description:

The MAC90C-0-GD-4-C/110-A-0/WI-1424/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It is intended for analog drive systems that require precise position and speed regulation in industrial automation. By providing direct rotary actuation, the unit couples motion controllers to mechanical loads in packaging machines, handling axes, and other automated equipment.

During continuous duty at standstill, the motor delivers 9.6 Nm while drawing 24.8 A; this torque-to-current relationship corresponds to a torque constant of 0.43 Nm/A. For brief acceleration bursts, the drive can supply up to 196 A, allowing the shaft to reach its nominal speed of 3000 rpm quickly. An internal tacho generator produces 3 V/1000 rpm, supporting analog velocity loops that track actual speed. Heat dissipates through natural convection, eliminating the need for a fan. The winding resistance of 0.24 Ω lets the current regulator maintain a stable waveform during operation. The motor is supplied without a blocking brake, so position holding must be managed by the drive or an external lock.

The housing aligns with machinery through a centering diameter of 110 mm and has a mass of 23 kg, giving the motor a compact yet substantial frame. Its IP65 protection rating guards the enclosure against dust ingress and water jets, permitting installation outside sealed cabinets. The rotor inertia is 53 × 10⁻⁴ kg·m², balancing fast response with load smoothing. A 60-minute thermal time constant indicates that the motor temperature rises gradually under sustained load. An incremental standard encoder supplies position feedback for drives that accept tacho and incremental inputs. With a winding inductance of 1.5 mH, the electrical time constant remains compatible with rapid current loops in analog control systems.
