Product Description:
The M-803-A-B9-G26-024 is a brushless servo motor built by Kollmorgen within the M Goldline Servo Motors series. It is intended for closed-loop positioning and velocity control where high continuous torque and dynamic response are required on packaging lines, material-handling axes, and machine tools. By pairing with a digital drive, the unit converts commanded current into shaft torque, allowing an automation controller to achieve precise motion profiles in industrial equipment. Its brushless design also supports repeatable motion during frequent start-stop cycles and changing load conditions.
This model delivers a continuous shaft torque of 42 N-m while drawing a continuous phase current of 24.9 Arms. Those values describe the steady operating load the motor can maintain without overheating. The motor is wound for 230 VAC line operation, and its back electromotive force is 102.3 Vrms/kRPM, so the drive must provide appropriate voltage as speed increases. A torque constant of 1.691 N-m/Arms links commanded current to produced torque, which makes motor response easier to predict during control. Six rotor poles set the electrical relationship between the drive and the motor speed, while the phase inductance and DC resistance affect current ripple, copper losses, and thermal behavior.
During rapid acceleration or shock loading, the motor withstands a peak torque of 130.2 N-m and a momentary current draw of 81 Arms, giving the axis additional force during short-demand events. Rated mechanical output is 7900 W at 37.71 N-m, showing how the motor converts electrical input into rotational power across its working range. The rotor inertia of 0.0352 kg-m² balances responsiveness with stability, which helps the axis settle without becoming overly sensitive to disturbances. Thermal resistance also affects how quickly heat moves from the windings to the frame, and that behavior helps predict temperature rise, support feedback selection, and match the motor to a compatible drive for accurate operation.
