Product Description:
The B-204-B-39-016 is a brushless servo motor manufactured by Kollmorgen within the Kollmorgen Goldline B and BH Motors series. It is intended for closed-loop positioning tasks in automated machinery where repeatable speed regulation and torque delivery are required for consistent throughput. This type of motor is typically paired with a servo drive that adjusts current in real time so the axis can respond quickly to changing load demands.
The motor delivers 4.47 N·m of continuous stall torque while drawing a continuous line current of 5.3 A RMS. During steady-state operation, the windings present 2.48 Ω of DC resistance, and their energy storage is characterized by an inductance of 38 mH. Back electromotive force is rated at 51.2 V RMS/kRPM, which indicates the voltage the drive must produce to maintain the commanded velocity. The shaft can run at a rated speed of 3600 RPM, which is also the maximum mechanical speed allowed by the design. The rotor has 4 poles, so electrical frequency requirements remain moderate. Line voltage must not exceed 250 V RMS, and the motor is intended for continuous service at ambient temperatures up to 40 °C.
Dynamic moves are supported by a peak torque capacity of 13.8 N·m and a corresponding peak line current limit of 17.2 A RMS. Together with a rotor inertia of 0.0001729 kg·m², these limits permit theoretical accelerations as high as 80,000 rad/s², enabling rapid indexing without overshoot. Nominal power output reaches 1.6 kW when the shaft is driven at rated speed, and energy conversion remains stable because the motor’s thermal path couples stator losses to the frame. Continuous duty within the stated ambient range helps prevent thermal saturation, preserve magnetic properties, and extend bearing life.
