4. Operating Principle
The Kollmorgen E33NCHA-LNN-NS-00 servo motor operates based on three-phase permanent magnet synchronous driving principle. The servo driver outputs variable-frequency and variable-voltage three-phase AC power to the stator winding to generate a rotating magnetic field, which drives the permanent magnet rotor to rotate synchronously and output precise power motion.
The built-in high-precision encoder collects real-time rotor speed, angle and position signals and feeds them back to the servo driver to form a closed-loop system. The driver dynamically corrects output current, voltage and frequency by comparing command values with actual operating values, realizing high-precision closed-loop control of position, speed and torque.
Optimized magnetic circuit and winding design suppress low-speed torque ripple and jitter effectively. The motor cooperates with the driver to complete overload current limiting, overheating protection and stall protection during operation, avoiding motor burnout and motion runaway caused by abnormal loads, and ensuring stable operation of automated stations.
