Product Description:
The H-234-F-0000 is a compact brushless servo motor engineered by Kollmorgen for the Silverline Brushless Servo Drives series. It supplies continuous, feedback-controlled torque for machinery that requires precise speed regulation, including automated feeders, test fixtures, and small gantry axes. Its frameless design allows original equipment manufacturers to integrate the stator and rotor directly into custom housings, reducing the space occupied by the motor. Direct integration also helps maintain thermal contact with surrounding structures during continuous operation in tightly packaged industrial equipment.
The motor draws a continuous phase current of 3.89 ADC, allowing its windings to sustain electromagnetic force without exceeding temperature limits during steady operation. Under these conditions, the shaft can operate at a rated speed of 4600 rpm while producing a rated torque of 0.621 N-m. During rapid indexing or sudden load changes, the drive can supply a peak phase current of 11.0 ADC. This temporary increase supports a peak torque of 1.99 N-m, providing the force needed to overcome short-term inertia or friction without stalling. The paired drive must manage continuous and intermittent operation through appropriate current limiting and motion control.
The motor generates a counter-electromotive force of 23.9 Vpk/krpm, so the drive must maintain sufficient voltage headroom as motor speed rises. Its per-phase inductance of 4.63 mH filters switching ripple and influences current-loop bandwidth, helping reduce torque ripple at high pulse-width modulation frequencies. A rotor inertia of 0.000023 kg-m² supports rapid speed changes without requiring excessive drive current, which is useful for repetitive indexing and pick-and-place motion. The motor has a mass of 1.27 kg, reducing the weight added to compact machine assemblies and end-of-arm tooling. Its combination of low inertia and compact frameless construction supports applications where responsive motion and limited installation space are important.
