Product Description:
The B-206-C-94-095 is a brushless servo motor built by Kollmorgen for the Goldline B and BH Motors series. In automated machinery, it transforms drive current into controlled torque and speed so positioning tables, gantries, or feeders can follow precise motion profiles. Its electromagnetic design allows closed-loop servo drives to regulate velocity and acceleration over a wide load range without the losses associated with a mechanical transmission. This operation supports applications that require responsive starts, controlled stops, and accurate movement under changing loads.
Under continuous duty at 25 °C, the motor delivers 6.83 N-m while drawing 10.0 A RMS from the amplifier; the available torque decreases to 6.44 N-m when the winding temperature reaches 40 °C. A torque constant of 0.62 N-m/A RMS links commanded current to shaft output, while a back EMF of 37.7 V RMS/kRPM indicates the regeneration voltage produced during deceleration. The maximum speed is 4900 rpm, and the mechanical output is rated at 2.8 kW. Short bursts can draw a peak line current of 33.0 A RMS to produce 19.5 N-m of peak torque for indexing movements or overcoming stiction. The stator has a phase inductance of 11 mH and a resistance of 0.82 Ω, which the drive uses when regulating current. Line voltage should not exceed 250 V RMS to protect the motor insulation and bearings.
The rotor inertia of 0.0002512 kg·m² supports fast and stable servo response. This inertia corresponds to a theoretical acceleration of 77,700 rad/s², allowing rapid changes in shaft speed during pick-and-place cycles. A thermal resistance of 0.62 °C/W indicates how readily heat moves from the windings to the housing. The motor has a frame weight of 7.6 kg, which contributes to its thermal mass and affects mounting requirements. Ambient airflow and the motor’s mounting surface influence heat dissipation during extended operation. The low-inertia rotor also reduces the energy required for acceleration and deceleration, helping the servo system track demanding motion commands without an external flywheel.
