Product Description:
For axis control tasks that need high power density, Kollmorgen manufactures the B-402-C-29-023 brushless servo motor. The unit belongs to the Goldline B and BH Motors series and is used with SERVOSTAR drives in multi-axis packaging, inspection, and material-handling equipment. As a permanent-magnet motor, it converts electrical energy from a matched servo amplifier into rotary motion while providing position feedback to the control system. By supporting four-pole operation, the device delivers responsive torque for precise industrial automation. This arrangement suits coordinated axes that require quick response and repeatable positioning during frequent speed changes.
Its electrical performance centers on a rated output of 2.8 kW, reached at 5000 rpm. The motor has 6.5 N-m of continuous stall torque, which is the torque it can produce continuously without overheating. The windings draw 9.8 A RMS and have 21 mH inductance plus 0.97 Ω resistance, which influence current rise time. The generated back electromotive force follows 40.2 V RMS/kRPM, so the drive must provide enough voltage margin at maximum speed. Line power is intended for 230 VAC with an upper tolerance of 250 V RMS. This electrical combination supports stable control across a wide operating range when the motor is paired with a suitable amplifier.
In transient motion profiles, the motor furnishes a peak torque of 19.8 N-m, driven by a momentary phase current limit of 31.3 A RMS. These short-term ratings allow rapid acceleration of loads with a rotor inertia of 0.000323 kg·m² while remaining below the magnetic saturation point. The torque constant is 0.66 N-m/A RMS, which supports current-loop tuning in the servo drive. With a thermal time constant of 22 minutes, repeated overloads can be spaced to limit winding temperature rise during cyclic motion. The housing weighs 8.4 kg, which supports compact installation in vertical or horizontal axes. That mass is moderate for a motor in this output class and helps where moving assemblies need controlled inertia.
