Miniature screw transformer control module

Get to know the miniature screw transformer module

Winding a transformer or building one always seems difficult and requires precise machinery. Of course, this is somewhat true, but let me change your perspective a bit and introduce to you a miniature transformer winding device (module) that you can use to create small-scale transformers, such as switching transformers. In other words, you can wind them yourself. We will talk more about this in the following, so stay with us.

A Compact Module for Automatic Transformer Winding

The field of electronics constantly evolves, and tools that simplify complex tasks are highly valuable for professionals and enthusiasts alike. Today, we introduce an innovative automatic transformer winding module designed for building ferrite core transformers, including switching power supply transformers (SMPS).

This DIY transformer winding module comprises two interconnected circuits:

1. Main Board
2. Control Handle Board

Together, these components provide precise control over the winding process, enabling seamless creation of high-quality transformers.

Main Board Features

The main board serves as the heart of the system, equipped with a microcontroller, driver circuits, and stepper motor controllers.

• Dual Stepper Motor Control:
  The module supports two stepper motors simultaneously, which is essential for transformer winding.
• Accurate Rotation Control:
  Users can specify the exact number of rotations for the primary stepper motor. For example, you can set the motor to rotate 10 turns and stop automatically.
• High Precision:
  The integration of driver circuits ensures smooth and accurate operation, crucial for winding uniform coils.

Control Handle Board

The control handle board is an intuitive interface for configuring motor parameters. It connects to the main board via a cable and allows:

• Setting the number of rotations for the primary motor.
• Managing start/stop functions seamlessly.

How It Works

1. Primary Motor Function:
   The first motor winds the enameled wire onto the transformer core or bobbin. Its precise rotations are critical for achieving uniform turns.

2. Secondary Motor Function:
   The second motor moves automatically left and right to guide the enameled wire evenly across the bobbin. This ensures perfect alignment and spacing of the wire on the core.

Applications

This module is ideal for building miniature transformer winding machines, enabling the creation of ferrite core transformers for switching power supplies and other compact electronic devices. With this system, users can:

• Build DIY SMPS transformers.
• Develop custom coil winding projects.
• Enhance efficiency in winding ferrite cores.

Why Use This Module?

1. Efficiency:
   Automates the transformer winding process, reducing manual labor.

2. Precision:
   The ability to set rotations and automate wire guidance ensures accurate and high-quality windings.

3. Versatility:
   Supports a wide range of DIY transformer projects, including custom designs for switching power supplies.

4. Compact Design:
   A miniaturized solution suitable for hobbyists and professionals alike.

Key Features at a Glance

• Dual stepper motor control for wire winding and alignment.
• Programmable rotation counts for consistent performance.
• Compact and modular design for various applications.

With this automatic transformer winding device, creating transformers for high-frequency electronics has never been easier. Whether you’re designing an SMPS transformer or a custom coil for a specialized application, this module simplifies the process and delivers professional results.
