Product Description:

The H-232-G-0712 belongs to Kollmorgen’s Silverline Brushless Servo Drives series. It serves as a compact drive-integrated motor for closed-loop positioning in pick-and-place axes, light conveyors, and indexing tables. By converting command current from a controller into precise electromagnetic torque, the unit delivers the speed modulation and rapid reversals required in modern industrial automation.

In continuous duty, the motor draws an armature current of 6.85 ADC and produces a stall torque of 0.415 N·m without overheating. Its thermal path has a resistance of 2.9 °C/W and an electrical time constant of 1.89 ms, so current rises quickly while heat dissipates more slowly. Rated operation occurs at a shaft speed of 4150 rpm with a corresponding torque of 0.374 N·m, yielding 162 W of mechanical power. The copper windings have a DC resistance of 0.497 Ω and an inductance of 0.941 mH, which are important values for current-loop tuning. For brief acceleration, the winding can accept 17.0 ADC and develop a peak torque of 0.93 N·m before approaching its demagnetization limits. The stator may be supplied by amplifiers with outputs up to 250 V rms line-to-line, matching typical 120/240 V bus converters.

Dynamic behavior at higher speeds is limited by a mechanical maximum of 6000 rpm and a back electromotive force constant of 7.21 Vpk/kRPM, which affect the required DC bus voltage as velocity increases. A rotor inertia of 1.7 × 10⁻⁵ kg·m² allows the axis to change speed quickly while maintaining high servo stiffness during small load disturbances. The assembly responds gradually to thermal changes, taking 8.1 min to reach 63% of a temperature step, so it can handle short overloads without immediate derating.
