Product Description:

The M-803-B-A1-B3 is a brushless servo motor produced by Kollmorgen as part of the M Goldline Servo Motors series. Its IP65 enclosure blocks dust and low-pressure water jets, allowing the motor to be mounted directly on machinery in packaging lines, conveyor stations, and gantry axes. In these systems, the motor converts drive current into precise rotary motion for position control and speed regulation. Feedback from the motor allows the connected drive to correct motion as operating loads change.

Under continuous load, the motor delivers a shaft output of 10,100 W at a rated speed of 2,750 rpm while producing 35.07 N·m of torque. A winding current of 32.4 A rms sustains that output, and the electromagnetic conversion sensitivity is 1.257 N·m/A rms, allowing the drive to calculate torque from measured phase current. For applications that require static force, the motor can supply 40.7 N·m of continuous stall torque without exceeding its thermal limits. Copper loss is moderated by a phase resistance of 0.2 ohm, while the laminated stator provides a path for heat dissipation. These operating values can be used to select compatible amplifiers, bus supplies, conductors, and protective devices for the motor circuit.

For peak motion demands, the motor can produce 129.2 N·m of torque at standstill. Its back electromotive force rises at 76 V rms/krpm, which allows the drive to account for generated voltage as speed increases. Mechanical responsiveness is supported by a rotor inertia of 0.0352 kg·m², while a coil inductance of 9.4 mH influences the rate at which winding current rises. The holding brake adds 56.4 mm to the motor’s overall length and contributes 0.000127 kg·m² of additional inertia. When supplied with 24 VDC, the brake clamps the shaft with 48 N·m of holding torque. This brake can secure a stationary load when the drive is not producing motor torque.
