| | | |

Winding the wire for a BLDC motor is a time-consuming and labor-intensive process. This winding machine automates this tedious tasks.

Motors

This machine uses four motors to perform the winding operation:

• M0: Move M1 unit (closed loop control)
• M1: Rotate the stator (closed loop control)
• M2: Wind the wire (closed loop control)
• M3: Adjust the wire tension (closed loop torque control using voltage)

code: Aotenjo One

Master Controller

All motors are controlled by Aotenjo Master, a master controller board based on the STM32G431CBU6 microcontroller. It communicates with the host computer via USB and controls the motors via CAN bus.

Prerequisites

• Miniconda: Download and install Miniconda for your operating system.

Installation

1. Clone the Winder repository:

   git clone https://github.com/aotenjo-xyz/winder.git
   

2. Navigate to the project directory:

   cd winder
   

3. Create a new conda environment and install the required dependencies:

   conda env create -f environment.yml
   

4. Activate the conda environment:

   conda activate winding
   export PYTHONPATH=$PWD
   

5. Create a settings.yml file based on settings-example.yml and update the settings as needed.

   cp settings-example.yml settings.yml
