Product Features

1 Closed-Loop Feedback Technology

At the heart of this DC Closed Loop Stepper Motor Drivers Kit is a sophisticated closed-loop control architecture. Each motor is equipped with a 1000PPR incremental encoder that continuously transmits real-time position data to the driver. The driver compares actual position against the commanded position and instantly adjusts current and phase to correct any deviation.

2 High Torque Density

The Nema23 frame delivers up to 3.5N.m of holding torque in a compact 57×57mm package, providing exceptional power-to-size ratio for space-constrained applications.

3 Advanced DSP Control

Built around a dedicated motor control DSP chip, the driver employs vector closed-loop control technology that significantly improves high-speed performance, reduces heat generation and vibration, and decreases overall power consumption.

4 Multiple Control Interfaces

• Pulse/Direction – Standard step and direction control

• RS485 Communication – Serial communication for parameter adjustment and monitoring

• EtherCAT – CiA402 Drive Profile compliant, CoE (CANopen over EtherCAT) protocol

5 Comprehensive Protection

Over-voltage, over-current, and tracking error protection functions ensure reliable operation and protect both the driver and motor from damage.

6 Easy Configuration

External digital debugging panel allows for simple parameter setting and real-time monitoring.

Product Technology & Working Principle

1 How It Works

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.
