Product Description:

The M-205-B-31-B3 is a permanent-magnet AC servo motor manufactured by Kollmorgen and assigned to the M Goldline Servo Motors series. It is intended to deliver precise torque and velocity control when paired with a matched drive and feedback device, making it suitable for positioning tables, pick-and-place heads, and similar industrial automation axes. By converting electrical power into controlled mechanical rotation, the motor permits closed-loop motion profiles that keep accuracy high even under changing load, temperature, and duty cycle conditions common on packaging lines and electronic assembly equipment.

During continuous operation, the winding set draws up to 5.3 Arms, a current level that maintains rated torque without overheating. At 40 °C, the motor produces 4.47 N-m of stall torque, so it can hold static loads while energized. The electromagnetic design supports a mechanical output of 1.6 kW, giving adequate power density for mid-frame machinery. Speed is electronically limited to 3600 RPM; above this point, back electromotive force would exceed insulation limits. Winding inductance of 38 mH filters current ripple and improves servo smoothness, while a back-EMF constant of 51.2 Vrms/kRPM indicates the voltage needed for a given shaft speed.

For rapid moves, the motor can reach a peak torque of 13.8 N-m, allowing short bursts of acceleration before magnetic saturation. Achieving this transient output demands a momentary phase current of 17.2 Arms, which the drive must supply without distortion. Once power is removed, thermal energy stored in the copper and lamination stack decays according to a time constant of 21 min; this relatively short lag supports predictable temperature modeling during cyclic duty. An optional 24 VDC spring-applied brake with 6.0 N-m of holding torque secures the load whenever the axis is de-energized.
