Product Description:

The B-206-B-33-B3 is a brushless servo motor manufactured by Kollmorgen within the Kollmorgen Goldline B and BH Motors series. It is built to supply tightly regulated torque and velocity for positioning tables, packaging machinery, and other automated axes that rely on high-performance motion control. Its brushless design supports repeatable response in systems that cycle frequently and need stable servo behavior over long operating periods. Integration with matched servo drives allows the motor to translate command currents into mechanical work while feedback devices track rotor position for closed-loop accuracy.

During continuous operation, the motor delivers a rated speed of 2800 RPM and a mechanical output of 1.80 kW. To maintain this operating point, it draws a continuous current of 5.8 Arms, and the thermal design supports bursts up to a peak torque of 19.9 N-m when supplied with a peak current of 19.5 Arms. Electrical conversion is supported by a back-EMF constant of 65.1 Vrms/kRPM, which relates inverter voltage to commanded speed. The winding has a DC resistance of 2.32 ohms that contributes to copper losses, and the torque constant of 1.08 N-m/Arms links drive current to shaft torque. Line power may be applied up to 250 Vrms, allowing the motor to reach rated output without insulation stress. These electrical values support stable torque production across the normal operating range of the motor.

At standstill, the motor can hold a stall torque of 6.24 N-m, and its magnetic circuit has an inductance of 32 mH that helps smooth current ripple during PWM switching. This behavior helps the current loop remain steady during low-speed motion and holding conditions. The integrated permanent-magnet brake secures vertical or load-suspended axes and produces a brake holding torque of 6.0 N-m when energized by 24 VDC at 1.27 A. This brake adds 40.3 mm of extra length and increases rotor inertia by only 2.47 × 10⁻⁶ kg·m², so the effect on dynamic response remains small.
