Product Description:
The H-344-H-0817 is a brushless servo motor produced by Kollmorgen as part of the Silverline Brushless Servo Drives series. Designed for precision motion in industrial automation, the unit converts controlled DC bus energy into rotation for pick-and-place gantries, indexing tables, and light packaging machinery. Its electromagnetic design supports continuous service while fitting into compact mechanical envelopes, making it suitable for axes where space, responsiveness, and consistent torque are required.
As a continuous-duty device, the motor delivers 2.10 N-m of stall torque while drawing 11.7 ADC of line current, producing 701 W of mechanical power without exceeding thermal limits. The rated operating point is 4050 RPM, yet the rotor can reach 6000 RPM under no-load conditions when supplied from a 250 Vrms source. A back electromotive force constant of 21.3 VO-PK/KRPM indicates the voltage that the drive must regulate during dynamic braking. The copper resistance of 0.360 Ω and inductance of 2.04 mH affect the current rise time, and the rated torque is 1.65 N-m. For short bursts, the windings can accept 32.6 ADC, providing additional current for rapid acceleration.
During fast indexing cycles, the servo can generate 5.26 N-m of peak torque, allowing the mechanism to overcome friction and load disturbances. A very low rotor inertia of 0.000092 kg-m² supports a theoretical acceleration of 57,300 rad/s², so commanded velocity changes can occur within milliseconds. Thermal energy is removed through a composite thermal path rated at 1.6 °C/W, and proper heat sinking prevents the winding temperature from surpassing its operating limit. The torque constant of 0.179 N-m/ADC allows the drive controller to calculate the commanded current directly from the required torque. This relationship also supports accurate control-loop tuning and fault diagnostics without adding unnecessary sensing hardware.
