Product Description:

The B-806-AA-91-TR517-008 is a brushless servo motor manufactured by Kollmorgen as part of the Kollmorgen Goldline B and BH Motors series. The unit converts electrical energy into precisely regulated rotary motion, allowing machine tools, packaging lines, and coordinated robotic axes to follow demanding speed and position commands in industrial automation. When paired with a compatible servo drive, it supports repeatable acceleration, controlled deceleration, and accurate closed-loop motion on axes that must respond quickly to changing loads. This makes it suitable for equipment that requires smooth torque delivery, repeatable path control, and stable response across changing process conditions.

The motor has a back-EMF constant of 133.7 Vrms/kRPM, which indicates the proportional voltage produced for every thousand revolutions and helps match the motor to a suitable drive voltage. During continuous stall, it can conduct 49.1 Arms while delivering 108.5 N-m of holding torque, describing the steady current and torque the stator can withstand thermally at zero speed. For short bursts, the windings allow a peak current of 153.8 Arms that produces up to 323 N-m, which supports fast acceleration and short-duration overloads. A torque constant of 2.21 N-m/Arms links commanded current to resulting torque, while 8 mH of phase inductance and 0.13 Ω phase resistance influence current response, drive bandwidth, and heating.

Rated operation is centered on 15 300 W of mechanical output while supplying a continuous running torque of 94.27 N-m on a 230 VAC bus, making the motor suitable for medium-power gantries, extruders, and other demanding motion systems. Dynamic response is aided by a rotor inertia of 0.0126 kg-m², which balances load matching with rapid speed changes during positioning or speed regulation. Heat moves from the windings to the housing through a thermal resistance of 0.16 °C/W. Temperature rise is averaged over a 55-minute thermal time constant, which supports stable performance during cyclic duty and longer repeating run profiles.
