The Lichuan DC Closed Loop Stepper Motor Drivers Kit operates on a closed-loop feedback principle that distinguishes it from conventional open-loop systems:
Step 1 – Command Input: The host controller (CNC controller, PLC, or motion control card) sends pulse/direction signals or serial commands to the driver, specifying target position and speed.
Step 2 – Motor Actuation: The driver energizes the motor phases according to the command, rotating the motor in precise 1.8° steps.
Step 3 – Real-Time Feedback: The 1000PPR incremental encoder mounted on the motor rear shaft continuously monitors actual rotor position and speed, feeding this data back to the driver.
Step 4 – Error Correction: The driver compares the encoder feedback against the commanded position. If any deviation is detected—due to load changes, resonance, or other disturbances—the driver instantly adjusts output current and phase timing to correct the error.
Step 5 – Stable Operation: This correction loop runs thousands of times per second, ensuring the motor maintains precise positioning even under varying loads, delivering servo-grade performance.
