Product Description:

Kollmorgen positions the H-342-H-0600 within its Silverline Brushless Servo Drives series, supplying a compact servo stage that converts direct current into controlled three-phase excitation for a matched brushless motor. In automated assembly lines, the unit delivers precise torque and speed regulation so that indexing tables, gantry axes, or small conveyors reach target positions without overshoot. The integrated feedback channel and commutation electronics allow the product to fit inside distributed motion nodes where cabinet space is limited.

During continuous operation, the amplifier supplies 12.0 A DC, a level that establishes the thermal load on the cabinet and supports steady-state torque. A continuous stall torque of 1.26 N·m holds the shaft at zero speed, while a peak output of 2.65 N·m covers acceleration demands. Feedback enters through an incremental encoder with 1000 LPR, providing 1,000 lines per revolution for the digital control loops. The phase winding has an inductance of 1.53 mH and a resistance of 0.318 Ω, establishing the electrical time constant and limiting current ripple. Line terminals accept up to 250 Vrms. The 120-degree Hall commutation system aligns the stator fields with the rotor magnets during operation.

The power section is capable of 470 W of continuous mechanical output, enough to drive small belt stages or rotary actuators within compact machines. Dynamic performance is supported by a rotor inertia of 0.000048 kg·m², which reduces acceleration time when commanded torque is applied. Heat transfer from the copper to the housing is represented by a thermal resistance of 1.7 °C/W, which helps determine enclosure cooling requirements. The square frame measures 3.44 inches on each side, and the overall length is 5.22 inches, allowing the assembly to fit into 90 mm class footprints. A back electromotive force constant of 12.5 V peak per krpm supports velocity estimation. The unit weighs 1.78 kg, helping to limit moving mass when it is installed on a linear carriage.
