Product Overview

Intelligent EtherCAT Motion Control with NEMA23 Stepper Technology

The Lichuan DC Open Loop Stepper Motor Drivers Kit EtherCAT combines traditional open-loop stepper motor technology with modern industrial Ethernet communication.

Unlike conventional pulse-only stepper drive systems, the EtherCAT configuration allows the drive to become part of a networked multi-axis motion-control architecture. This makes it suitable for equipment manufacturers and system integrators looking for a compact, cost-effective alternative for applications that require coordinated axis control.

The product family is available in multiple torque configurations:

0.6N.m / 1.2N.m / 1.8N.m / 2.0N.m / 2.4N.m / 3.0N.m / 3.5N.m

and driver current configurations of:

2.5A / 4.0A

with a DC power input range of:

DC24V–50V

Basic Product Information

Note: Exact motor electrical characteristics, dimensions, inductance, resistance, shaft dimensions and detailed EtherCAT functions should be confirmed according to the selected motor/driver SKU and technical datasheet.

Product Description

The Lichuan DC Open Loop Stepper Motor Drivers Kit EtherCAT provides a practical solution for machine builders who need coordinated stepper-axis motion without the additional cost and complexity of a full servo system.

The NEMA23 stepper motor produces incremental rotary motion while the EtherCAT stepper driver receives motion commands through the industrial Ethernet network.

The overall architecture can be represented as:

Industrial Controller → EtherCAT Network → EtherCAT Stepper Driver → NEMA23 Stepper Motor → Mechanical Axis

This configuration allows multiple motor axes to be integrated into a centralized machine-control architecture while retaining the simplicity of an open-loop stepper system.

Product Features

EtherCAT Industrial Communication

The EtherCAT version of the DC Open Loop Stepper Motor Drivers Kit is designed for networked motion-control architectures, making it suitable for synchronized multi-axis machine systems.

NEMA23 Standard Motor Frame

The NEMA23 mechanical format provides broad compatibility with CNC machines, linear stages, ball-screw mechanisms, belt-driven axes and automation equipment.

DC24V–50V Power Supply

The wide DC input range supports flexible system power architecture and allows the kit to be integrated into different machine-control platforms.

2.5A and 4.0A Driver Options

Different current configurations allow users to select the appropriate driver according to the motor winding specification and mechanical load.

Seven Torque Configurations

The motor family provides:

0.6 / 1.2 / 1.8 / 2.0 / 2.4 / 3.0 / 3.5N.m

This provides a broader selection range for machine designers than a single fixed motor configuration.

Open-Loop Architecture

The system does not depend on an external encoder for normal operation, reducing system complexity, wiring requirements and overall component count.

Multi-Axis Automation

EtherCAT networking makes the product particularly suitable for applications that require centralized communication and coordinated motion across multiple machine axes.

Product Selling Points

Customers can purchase a matched motor and driver configuration rather than independently selecting and matching components.

3. Seven Torque Options

The 0.6–3.5N.m range provides flexible system sizing for compact and medium-duty machine axes.

4. Wide DC Voltage Range

DC24V–50V allows system designers greater flexibility when selecting the power supply.

5. Industrial Automation Ready

The EtherCAT architecture makes the kit suitable for centralized machine networks, synchronized axes and modern automation equipment.

6. Cost-Effective Alternative for Suitable Applications

For applications where encoder feedback is not required, an open-loop stepper system can provide a simpler motion-control architecture than a closed-loop servo system.

EtherCAT Technology

What Is EtherCAT?

EtherCAT is an industrial Ethernet communication technology designed for high-speed, deterministic communication between industrial controllers and distributed devices.

In the Lichuan DC Open Loop Stepper Motor Drivers Kit EtherCAT, the driver acts as a networked motion device between the machine controller and the stepper motor.

A typical system structure is:

PLC / IPC / Motion Controller

↓

EtherCAT Master

↓

EtherCAT Stepper Driver

↓

NEMA23 Stepper Motor

↓

Lead Screw / Ball Screw / Belt / Mechanical Load

This architecture allows multiple drives to be connected through a common industrial communication network.

Working Principle

How the DC Open Loop Stepper Motor Drivers Kit Works

The system converts networked motion commands into controlled motor phase current.

Step 1 – Motion Command

The EtherCAT master sends motion information to the stepper driver.

Step 2 – Drive Processing

The EtherCAT driver interprets the received motion command and generates the required motor-control sequence.

Step 3 – Phase Excitation

The driver supplies controlled current to the two motor phases.

Step 4 – Rotor Movement

The magnetic field generated inside the motor causes the rotor to move incrementally.

Step 5 – Mechanical Transmission

The motor converts rotary motion into machine-axis movement through a lead screw, ball screw, belt, rack-and-pinion mechanism or other transmission system.

Open-Loop Motion Technology

The DC Open Loop Stepper Motor Drivers Kit is designed for applications where position feedback is not required for normal operation.

The controller commands the desired movement, and the motor follows the electrical excitation sequence.

The main benefits are:

Simple architecture

Reduced wiring

Lower component count

Cost-effective system design

Easy replacement and maintenance

However, open-loop operation also means that the motor should be correctly sized for the actual machine load, acceleration and operating speed.

Excessive load or acceleration may cause missed steps.

Torque Configuration

Available NEMA23 Motor Torque Options

The appropriate motor should be selected according to:

Load → Acceleration → Speed → Transmission → Friction → Safety Margin

Holding torque should not be treated as the same value as available torque during high-speed operation.

Driver Current Options

The DC Open Loop Stepper Motor Drivers Kit EtherCAT supports driver-current configurations including:

The driver should be matched with the motor's rated winding current.

Selecting a driver based only on the maximum current rating is not recommended. The motor winding specification and actual machine operating conditions should be considered together.
