Product Description:
The M-405-A-A1 servo motor is manufactured by Kollmorgen and belongs to the M Goldline Servo Motors series. This brushless, three-phase unit converts electrical energy into controlled rotational motion for automated machinery. By coupling its shaft to gearboxes, ball screws, or direct-drive mechanisms, the motor enables precise positioning and speed regulation in packaging lines, electronic assembly cells, and material handling equipment during continuous duty cycles.
At the electrical interface, the motor is designed for a line supply up to 250 VRMS and draws a continuous phase current of 6.0 A RMS while delivering 2.0 kW of mechanical output at the rated operating point of 1500 RPM. The copper windings present 4.10 Ω of DC resistance and an inductance of 102 mH, parameters that influence drive tuning and the motor’s transient current rise. A torque constant of 2.31 N-m/A RMS links current to developed torque and allows drives to translate command currents directly into motion. Kollmorgen supplies the frame with a Standard Metric Mount so it bolts to common IEC flanges, and the connector package is shipped without mating plugs to let builders select their own cable sets for field installation.
For static loading, the motor can hold 13.0 N-m of stall torque at 40 °C, and during acceleration it reaches a peak capability of 35.9 N-m while drawing up to 16.4 A RMS from the amplifier. The generated back electromotive force is 139.0 VRMS/kRPM, a value the controller monitors to prevent regenerative overvoltage when the axis decelerates. Dynamic moves are aided by a rotor inertia of 0.00441 kg-m², giving a balance between quick response and mechanical stability. An IP65 sealing system protects the housing from dust and low-pressure water jets, and a rear shaft extension is included for mounting feedback devices or secondary loads. The motor ships ready for service once it is fastened and cabled, with thermal sensors supported by the drive for overload protection.
