Product Description:
The M-605-A-A3 is a brushless servo motor produced by Kollmorgen as part of the M Goldline Servo Motors series. The unit is designed for closed-loop motion axes where accurate torque delivery and repeatable speed are required to position tooling, conveyors, or rotary actuators in industrial automation cells. Integrated rare-earth magnets, a six-pole rotor, and resolver feedback allow the drive to regulate current vector and maintain commanded motion profiles under changing mechanical loads.
At stall, the motor can deliver 30.1 N-m of continuous torque while drawing 19 Arms from the drive; this is the sustainable load that can be held indefinitely without exceeding winding temperature limits. During short acceleration bursts, the electromagnetic system supports a peak torque of 86.4 N-m with a corresponding current demand of 57.4 Arms, giving the axis headroom to overcome inertia and friction. Once at speed, the shaft produces 26.65 N-m at a rated velocity of 2150 rpm, which corresponds to a mechanical output of 6000 W. A torque constant of 1.584 N-m/Arms links commanded phase current to developed torque, and the back-EMF profile supports stable voltage generation for commutation. Continuous stall current, peak limits, and thermal ratings must be considered when sizing the drive amplifier and selecting protective fusing.
The electromagnetic constants govern electrical matching. A back EMF of 95.78 Vrms/kRPM indicates the induced voltage at speed and influences the required DC bus level. Winding impedance is characterized by a DC resistance of 0.51 ohms and an inductance of 13.3 mH, factors that affect current ripple and drive bandwidth. The steel rotor carries 0.0141 kg·m² of inertia, providing moderate energy storage for damping load disturbances. Overall length is 436.4 mm, and the rotor layout distributes flux evenly around the stator. Thermal behavior is modeled with a resistance of 0.28 °C/W and a time constant of 33 min, indicating how quickly the frame temperature rises during sustained duty cycles.
