Product Description:

The M-813-B-A9-B2S-053 is a brushless servo motor produced by Kollmorgen within the M Goldline Servo Motors series. It is intended for closed-loop positioning and velocity tasks in automated machinery. Rapid torque response and repeatable motion help synchronize tooling, conveyors, or robotic joints with the controller's command profile.

The motor can deliver a continuous shaft output of 40.7 N-m while drawing a steady phase current of 32.4 A RMS. This combination marks the thermally limited operating point for applications that run for extended periods. A torque constant of 1.26 N-m/A RMS links commanded current to mechanical torque, allowing the drive to calculate precise setpoints. With a rated speed of 2750 rpm, the machine reaches its rated mechanical power of 10.1 kW within the continuous operating range. The armature's 0.200 Ω DC resistance and 9.4 mH phase inductance affect current rise time and copper losses, which the drive must account for during high-frequency current loops. An integral holding brake is energized at 90 VDC, draws 0.39 A, and supplies 48.0 N-m of static torque to secure vertical or suspended loads when power is removed. Line supplies up to 250 VRMS may be connected without exceeding insulation limits, and the rotor's 0.0352 kg·m² inertia supports stable servo performance when driving sizable external loads.

During acceleration or shock events, the stator can supply a peak shaft torque of 129 N-m by permitting the windings to momentarily carry 108 A RMS. The generated back electromotive force reaches 76.0 VRMS/kRPM, a value the drive must match with adequate DC-bus voltage to avoid field weakening at high speed. An IP67 housing prevents dust ingress and withstands temporary immersion, expanding installation options to washdown or outdoor stations. These peak capabilities extend the continuous operating range without changing the steady-state thermal limits.
