Product Description:
The B-602-C-A1-B3 is a brushless servo motor manufactured by Kollmorgen for the Goldline B and BH Motors series. The motor has a metric frame, an IP65 sealing arrangement, and a rear shaft extension for connection to compatible machinery. It is intended for precision rotary axes in automated packaging lines, pick-and-place robots, and similar equipment. The motor converts drive current into controlled torque and speed, allowing a motion controller to position loads quickly and repeatably. Its compact housing supports installation where available machine space is limited.
Under continuous stall conditions, the motor sustains 17.36 N-m while drawing 15 Arms. This performance corresponds to a torque constant of 1.16 N-m/Arms, which relates commanded current to the torque produced at the shaft. The back electromotive force is rated at 70 Vrms/kRPM, providing the drive with the expected generated voltage relative to rotor speed. The copper windings have a DC resistance of 0.67 ohms and an inductance of 14 mH, supporting controlled current response during servo operation. An integral holding brake provides 48.0 N-m of static torque to secure the shaft when motion is stopped. The brake operates from a 24 VDC supply and draws 1.27 A when energized. Electrical connections use a screw-thread connector package that is supplied without mating plugs.
During commanded motion, the rotor reaches a rated speed of 3000 rpm and delivers a rated torque of 14.48 N-m. At this operating point, the motor produces 4550 W of mechanical output power for continuous machine operation. For rapid acceleration or disturbance rejection, the electromagnetic assembly tolerates a peak stall torque of 49.5 N-m for short intervals. A rotor inertia of 0.00103 kg-m² supports responsive acceleration while helping the servo loop maintain stable velocity regulation. This inertia allows the controller to command high-bandwidth movements without creating excessive mechanical lag. Peak torque capacity also provides additional force for temporary load changes that exceed the continuous operating level.
