Product Description:
The B-604-C-B1 is an AC servo motor built by Kollmorgen and supplied within the Kollmorgen Goldline B and BH Motors series. As a drive element in industrial automation, this motor converts commanded current into precise rotary motion for positioning tables, packaging axes, and similar equipment that require closed-loop velocity and torque control. Its IP65 sealing keeps out dust and low-pressure water jets so the unit can reside on machines without a separate enclosure.
During steady operation, the motor draws a continuous phase current of 39.4 A RMS, and at that level it produces 31.2 N-m of torque at the flange while the stator winding remains at 40 °C. Coupled with a rated shaft speed of 4300 rpm, these values correspond to a mechanical output of 8.6 kW, suitable for mid-power indexing or web-handling duties. The winding inductance of 3.3 mH shapes the current rise time and influences drive tuning, while a direct current resistance of 0.126 Ω contributes to copper losses under load. Screw-thread power and feedback connectors are fitted, and the mating plugs are supplied to simplify cable installation. Position feedback is provided by a frameless resolver, and the frame mounts with standard metric holes. An integral rear shaft extension is present for auxiliary encoders or brakes.
When rapid acceleration is demanded, the drive can deliver a phase surge of up to 114.8 A RMS, allowing the electromagnetic structure to generate a momentary shaft torque of 86.4 N-m. This peak reserve accelerates inertial loads quickly and overcomes short-term disturbances without stalling. A back electromotive force constant of 47.9 VRMS/kRPM indicates the voltage that the servo amplifier must track as speed rises, ensuring the 600 V-class drive bus has adequate margin. The rotor’s mass moment of 0.002034 kg-m² minimizes kinetic energy, permitting high-bandwidth motion profiles while limiting regenerative energy during deceleration.
