Product Description:

The MAC090B-0-PD-1-B/110-A-1/I625/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts three-phase electrical power into controllable mechanical output so that automated tools, transfer stations, and packaging actuators can follow commanded motion profiles. Its construction pairs a permanent-magnet rotor with a blocking brake, giving machine builders a compact prime mover that can hold load position after power removal.

The motor’s flange has a centering diameter of 110 mm, allowing precise alignment with gearboxes or machine housings. Under continuous stall conditions, it delivers 7.2 Nm while drawing 11.9 A; these values describe the sustained torque and current level required from the drive without exceeding thermal limits. Shaft speed reaches 1500 min⁻¹, a value associated with the PD winding and suited to moderate-speed machining tasks. Torque rises proportionally to phase current at a rate of 0.67 Nm/A, enabling predictable control through current regulation. Natural convection removes heat from the stator, phase resistance at 20 °C is 0.97 Ω, an incremental encoder supplies position data, the tacho generator outputs 3 V per 1000 min⁻¹ for velocity feedback, power enters through a connector on side A, and the winding code is PD.

With a mass of 18 kg, the motor adds moderate structural load to the axis. Short acceleration bursts are supported because the drive can momentarily furnish up to 86 A, while the rotor inertia of 0.0036 kg·m² balances quick response with damping against load disturbances. The stator’s phase inductance of 5.1 mH limits current ripple during switching events. The 60-minute thermal time constant indicates how long the windings need to approach a steady operating temperature when cooled only by ambient airflow.
