Product Description:

The B-606-AA-99-TR12-088 is a brushless servo motor manufactured by Kollmorgen as part of the Goldline B and BH Motors series. The unit is intended for industrial automation axes that require precise, repeatable torque delivery and smooth speed regulation. When paired with a compatible drive, it converts electrical input into controlled mechanical rotation, allowing conveyors, pick-and-place heads, or packaging mechanisms to position loads accurately. Feedback is provided through a size-11 resolver, so the controller can track rotor position during operation.

At the electrical interface, the motor draws a continuous current of 20.0 A RMS to produce a continuous shaft torque of 44.8 N-m. During acceleration, current can rise to 62.0 A RMS, enabling a peak torque of 132.0 N-m for short transients. Electromagnetic response is supported by a winding inductance of 15.6 mH together with a coil resistance of 0.500 Ω measured at 25 °C, allowing the drive to regulate current quickly without excessive heating. The back electromotive force constant is 135 VRMS per kRPM, which supports drive voltage scaling from a 230 VAC line supply while remaining within the 250 VRMS line-to-line limit. Tachometer ripple is held to 0.6% average-to-peak, improving speed feedback fidelity for tight velocity loops. With a torque sensitivity of 2.24 N-m/A RMS, commanded current is translated predictably into shaft torque.

Under steady load, the shaft delivers 6.6 kW of mechanical output while running at its rated speed of 1550 rpm. A low rotor inertia of 0.00304 kg·m² supports fast angular acceleration, which helps the motor respond quickly in indexing applications that require rapid starts and stops. This combination of speed, power, and inertia suits motion profiles that need responsive acceleration without sacrificing stable operation. The motor can be used on automated axes where repeatable movement and controlled velocity are both important.
