Product Description:

The B-606-DD-99-TS-268 is a brushless AC servo motor produced by Kollmorgen and assigned to the Kollmorgen Goldline B and BH Motors series. This frame size provides direct-coupled rotary actuation for automated presses, material-handling stations, coordinated gantry axes, and similar motion systems. Within an integrated servo loop, the motor converts drive current into precisely controlled shaft torque, supporting cycles that demand both steady load holding and rapid overload bursts.

Designed for three-phase installations, the motor operates on a nominal supply of 230 VAC while tolerating up to 250 VRMS from the drive to accommodate bus transients. It can deliver a continuous phase current of 28.0 A RMS, and the controller may command 86.2 A RMS for short periods during the acceleration of high-inertia loads. Stall capability reaches 44.6 N-m at 25 °C and declines slightly to 42.0 N-m at 40 °C, illustrating the effect of winding temperature on torque production. For rapid indexing moves, a peak output of 123.0 N-m is available. Dynamic response is shaped by the phase impedance; a resistance of 0.26 Ohms limits copper losses, and an inductance of 7.0 mH filters the PWM switching edges from the amplifier. The six-pole rotor produces a balanced electromagnetic field, and a thermal resistance of 0.25 °C/W describes heat flow from the housing into ambient air.

At its maximum rated power of 8.2 kW, the shaft can attain 2300 rpm while remaining within the servo drive's voltage headroom. The electromechanical link between current and motion is quantified by a torque constant of 1.2 N-m/A RMS, so the drive can estimate load torque directly from measured phase current. The generated back electromagnetic force is proportional to speed according to the motor constant of 90.5 VRMS/kRPM, which helps establish voltage limits during regenerative deceleration. This relationship also helps the controller manage high-speed operation without exceeding available bus voltage.
