Lichuan DC Closed Loop Stepper Motor Drivers Kit – 0.45/0.52/0.8N·m 2-Phase Nema17 DC24V–50V 2.5A 1000PPR

Product Overview

The Lichuan DC Closed Loop Stepper Motor Drivers Kit is a high-performance motion control solution designed for industrial automation, precision machinery, and robotics applications. This kit integrates a digital closed-loop stepper driver with a NEMA17 hybrid stepper motor and a 1000PPR incremental encoder feedback system, delivering servo-like positioning accuracy at a fraction of the cost of traditional servo systems.

Available in three torque options—0.45N·m, 0.52N·m, and 0.8N·m—this DC Closed Loop Stepper Motor Drivers Kit operates on a DC24V–50V power supply with a 2.5A rated current, making it ideal for compact automation equipment and precision motion control systems. The closed-loop control technology continuously monitors the motor's actual position via the encoder and automatically corrects any deviation in real time, effectively eliminating step loss and improving motion stability.

Whether you are upgrading from an open-loop system or building a new precision motion platform, the Lichuan DC Closed Loop Stepper Motor Drivers Kit offers the perfect balance of performance, reliability, and affordability.

Technology & Working Principle

How It Works

The DC Closed Loop Stepper Motor Drivers Kit operates on a closed-loop feedback control principle that fundamentally transforms how stepper motors perform. The system works through the following sequence:

1. Command Input – The controller sends pulse/direction signals to set the target position and speed.

2. Current Drive – The 32-bit DSP generates optimized PWM current waveforms to drive the stepper motor.

3. Encoder Feedback – The 1000PPR encoder mounted on the motor continuously detects the rotor's actual position and feeds this data back to the driver.

4. Error Comparison – The driver compares the encoder's actual position feedback against the commanded target position to calculate any deviation.

5. Closed-Loop Correction – Based on the error signal, the DSP dynamically adjusts the output current amplitude and phase angle, driving the motor toward the target position until the error is eliminated.

Technology Advantages

Unlike traditional open-loop stepper systems, where the driver assumes the motor follows each command without verification, the DC Closed Loop Stepper Motor Drivers Kit actively monitors and corrects motion in real time. When load increases and the motor rotor begins to lag behind the commanded position (i.e., "step loss"), the encoder immediately detects this deviation, and the driver responds by increasing current or adjusting the phase angle to "pull" the rotor back into the correct position. This mechanism ensures precise positioning even under high-speed and high-load conditions.

FAQ (Frequently Asked Questions)

Q1: What is the difference between this DC Closed Loop Stepper Motor Drivers Kit and an open-loop stepper driver?

A: The closed-loop kit uses a 1000PPR encoder to provide real-time position feedback, allowing the driver to detect and correct step loss. Open-loop drivers cannot sense the motor's actual position and will inevitably lose steps under excessive load.

Q2: What voltage range does this kit support?

A: The kit supports DC24V–50V wide-range input, accommodating various industrial power environments.

Q3: What motor frame sizes are compatible?

A: This DC Closed Loop Stepper Motor Drivers Kit is designed for NEMA17 (42×42mm) frame stepper motors.

Q4: What is the encoder resolution?

A: The kit features a 1000PPR incremental encoder providing precise position feedback.

Q5: What torque options are available?

A: This kit is available in 0.45N·m, 0.52N·m, and 0.8N·m holding torque options.

Q6: What is the minimum order quantity?

A: The minimum order quantity is 1 set.

Q7: What certifications does this product have?

A: The product is certified with ISO9001, CE, RoHS, EPR, EMC, LVD, and IEC/EN60034-1.
