Product Description:
The H-342-H-0802 is a brushless servo motor produced by Kollmorgen within the Silverline Brushless Servo Drives series. It converts three-phase electrical power from a compatible servo drive into controlled rotary motion for compact conveyor sections, indexing tables, and light manufacturing stations. Closed-loop speed and torque control allow the motor to follow commanded motion profiles accurately under changing loads. Its brushless design eliminates mechanical brush wear and supports consistent operation during repetitive motion cycles.
The motor provides a continuous stall torque of 1.26 N-m, which it can maintain without overheating when operated under the required thermal conditions. The shaft reaches a rated speed of 6000 rpm, supporting high-speed duty cycles in small-diameter tooling and other compact mechanisms. During acceleration, the motor can accept a peak line current of 28.0 A to produce short-term peak torque. The stator windings have an inductance of 1.53 mH, which affects current ripple and the response of the drive’s current-control loop. A back electromotive force constant of 12.5 V-pk/krpm relates motor speed to generated voltage and assists with selecting a compatible bus voltage. These electrical characteristics allow the connected controller to regulate current during rapid changes in speed or load.
Continuous power dissipation at the nominal operating point is 470 W, which must be considered when planning enclosure airflow and thermal management. The rotor inertia is 0.000048 kg-m², allowing fast position corrections without requiring excessive torque for acceleration. The complete assembly weighs 1.78 kg and includes a 1000-line-per-revolution optical encoder for position and speed feedback. Its relatively low mass helps limit the load placed on machine structures, particularly when the motor is installed on a moving axis. Electrical insulation supports a maximum line-to-line potential of 250 Vrms, so connected cables and nearby conductors must maintain suitable insulation and clearance for that voltage. The encoder supplies the feedback needed by the servo controller to correct motion errors during operation.
