Product Description:

Kollmorgen’s H-344-H-0000 belongs to the Silverline Brushless Servo Drives series and serves as a compact brushless servo motor for high-performance motion axes in automated machinery. The unit pairs with digital controllers to provide precise velocity, torque, and position regulation, enabling coordinated movement in pick-and-place modules, feeders, and small gantries. Its design supports continuous-duty operation while maintaining a responsive motion profile, making it suitable for repetitive industrial tasks that require accurate, low-maintenance drive solutions. Closed-loop control allows the connected drive to correct motion errors as operating loads and commanded speeds change.

Under nominal loading, the motor can supply 701 W of mechanical output continuously without exceeding its thermal limits. With a continuous phase current of 11.7 A DC, the windings sustain the magnetic field needed for closed-loop regulation during extended operating cycles. Shaft torque at standstill reaches 2.10 Nm, allowing linear or rotary mechanisms to remain stationary while the motor is energized. For applications that require rapid indexing, the rotor has a rated speed of 4050 rpm, enabling high surface speeds while remaining within the continuous operating range. The back EMF constant is 21.3 V peak/krpm, indicating how much opposing voltage is generated as rotational speed increases. This electrical characteristic helps the controller regulate current and maintain the commanded motion at higher speeds.

Dynamic overload events can be handled with a peak phase current of 32.6 A DC, allowing the motor to provide short bursts of 5.26 Nm when accelerating loads. The phase-to-phase resistance is 0.360 Ω, which affects winding losses and motor temperature during operation. A stator inductance of 2.04 mH influences current ripple and the response of the controller’s current loop. Three pole pairs work with the resolver to support smooth electronic commutation throughout each revolution. The rotor inertia is 0.000092 kg·m², helping the motor settle quickly after rapid changes in speed or direction.
