DC Open Loop Stepper Motor Drivers Kit – EtherCAT NEMA24 2-Phase 24V–50V 4.0A

High-Torque EtherCAT Stepper Motor and Driver Kit for Industrial Motion Control

The Lichuan DC Open Loop Stepper Motor Drivers Kit is an EtherCAT-based motion control solution combining a high-torque 2-phase NEMA24 stepper motor with a digital stepper motor driver.

Designed for industrial automation, CNC machinery, positioning equipment and multi-axis motion applications, this DC Open Loop Stepper Motor Drivers Kit offers multiple holding torque options from 1.6 N·m to 4.0 N·m, with a DC24V–50V power supply range and 4.0A drive current configuration.

By combining NEMA24 mechanical performance with EtherCAT network communication, the system is designed to provide a practical, scalable and cost-effective solution for machine builders, OEM manufacturers, automation integrators and professional users.

Product Overview

The Lichuan DC Open Loop Stepper Motor Drivers Kit is developed for applications requiring reliable incremental motion, high holding torque and EtherCAT-based multi-axis communication.

Compared with conventional pulse-only stepper systems, an EtherCAT architecture can simplify multi-axis system integration and provide centralized communication between the motion controller and individual drives.

The NEMA24 stepper motor platform offers higher torque capacity than many compact NEMA17 or NEMA23 systems, making this kit suitable for applications where stronger mechanical output is required without moving immediately to a servo system.

The product is available in several torque configurations:

1.6 N·m / 2.1 N·m / 2.5 N·m / 3.0 N·m / 3.5 N·m / 4.0 N·m

Basic Product Information

Key Features

1. EtherCAT Industrial Communication

The DC Open Loop Stepper Motor Drivers Kit is designed for EtherCAT-based motion-control systems.

EtherCAT communication allows multiple drives to be connected within the same industrial network, making the solution suitable for coordinated multi-axis applications.

For machine builders and automation engineers, this architecture can simplify control-system design compared with large numbers of individual point-to-point motion signal connections.

2. NEMA24 High-Torque Stepper Motor

The NEMA24 motor provides a larger mechanical platform for applications requiring higher torque than smaller stepper motor sizes.

With available holding torque up to 4.0 N·m, the system is suitable for medium- to higher-load positioning applications.

3. Six Torque Options

The DC Open Loop Stepper Motor Drivers Kit is available in six torque levels:

Actual motor selection should consider speed, acceleration, load inertia, transmission ratio, screw lead and duty cycle rather than holding torque alone.

4. DC24V–50V Power Supply

The kit is designed for a DC24V–50V power supply architecture, providing flexibility for different industrial control-panel power configurations.

5. 4.0A Drive Current

The 4.0A driver configuration is designed to provide the current required by the corresponding high-torque NEMA24 stepper motor configuration.

Current settings should always be matched to the selected motor specification.

6. Open-Loop Motion Control

The system operates as an open-loop stepper solution without encoder feedback for continuous position correction.

This makes the system simpler and more economical than encoder-based solutions for applications that do not require closed-loop error correction.

7. Multi-Axis Motion Capability

EtherCAT communication makes the system suitable for machine architectures involving multiple synchronized motion axes.

Typical applications include XYZ positioning systems, CNC equipment, automated assembly machinery and industrial linear-motion equipment.

DC Open Loop Stepper Motor Drivers Kit Technical Specifications

Technical details such as rated current, peak current, inductance, resistance, speed-torque characteristics, dimensions, connector definition and protection functions should be confirmed against the datasheet of the selected motor-driver configuration.

Product Technology

The DC Open Loop Stepper Motor Drivers Kit converts digital motion commands into controlled motor rotation through a sequence of electrical phase currents.

The basic control chain is:

EtherCAT Motion Command → Stepper Driver → Phase Current Control → NEMA24 Motor → Mechanical Motion

The EtherCAT controller sends the required motion information to the driver.

The digital driver processes the command and controls the current supplied to the two motor phases.

The resulting electromagnetic field causes the stepper motor rotor to move in controlled increments.

The motor then transfers the rotary motion to the machine through a lead screw, ball screw, belt drive, rack-and-pinion mechanism or other mechanical transmission.

How Does the DC Open Loop Stepper Motor Drivers Kit Work?

Step 1 – Motion Command

A PLC, industrial PC or EtherCAT motion controller generates the required position, speed or motion command.

Step 2 – EtherCAT Communication

The motion command is transmitted through the EtherCAT network to the designated stepper driver.

Step 3 – Digital Drive Processing

The driver processes the command and controls the motor phase current according to its configured operating parameters.

Step 4 – Electromagnetic Motion

The two-phase NEMA24 motor converts electrical energy into incremental rotary motion.

Step 5 – Mechanical Output

The motor shaft drives the connected mechanical transmission and generates linear or rotary machine movement.

This open-loop architecture is particularly appropriate for applications where high holding torque, repeatability and economical motion control are more important than encoder-based feedback.

Torque Selection Guide

Choosing the correct DC Open Loop Stepper Motor Drivers Kit should begin with the actual mechanical load rather than the motor's maximum torque value.

For engineering selection, always account for acceleration, target speed, transmission efficiency, load inertia and safety margin.

Installation and Operating Method

1. Confirm the Specifications

Before installation, confirm:

• NEMA24 motor model
• Torque requirement
• Motor current
• Driver current
• DC supply voltage
• EtherCAT controller compatibility
• Mechanical transmission requirements

2. Mount the Motor

Install the NEMA24 motor on a rigid and accurately aligned mounting surface.

Avoid excessive shaft loads or mechanical misalignment.

3. Connect the Power Supply

Connect the DC power supply according to the driver wiring diagram.

Verify voltage and polarity before power-up.

4. Connect the Motor

Connect the two motor phases according to the manufacturer's wiring definition.

5. Connect EtherCAT

Connect the EtherCAT communication network between the controller and driver.

6. Configure the Driver

Set the required communication and motion parameters according to the controller and driver documentation.

7. Perform a Low-Speed Test

Run the motor at low speed first.

Check:

• Rotation direction
• Vibration
• Noise
• Communication status
• Mechanical interference
• Motor temperature

8. Start Normal Operation

After confirming stable operation, gradually increase the required speed and acceleration.

Safety Precautions

Power Supply

Use only the recommended DC24V–50V operating range for the applicable product configuration.

Current Setting

Do not exceed the rated current of the selected NEMA24 motor.

Wiring

Always check motor phase wiring and power polarity before energizing the system.

Thermal Management

Maintain adequate ventilation and heat dissipation around the driver.

Mechanical Load

Do not exceed the motor's effective torque capability at the required operating speed.

Open-Loop Limitation

An open-loop system does not continuously verify actual rotor position through encoder feedback. Applications with high external disturbance, extreme acceleration or strict position-error monitoring may require a closed-loop or servo solution.
