Lack of Gimbal Motors

I've working on building a motor winding machine for over two months. The primary reason I started this project was that I wanted to create a gimbal motor for robotics projects. However, I found that gimbal motors are not as available and affordable as drone motors.

Here is a short vidoe of the motor winding machine I built.

Rise of the Gimbal Motor Price​

I bought six GBM5208-75T motors this summer for $20 each and I broke two of them. I wanted to buy more, but the price has risen to $50 each. I found that the price of gimbal motors has increased significantly in the past few months. I didn't want to wind the motor by hand because it is time-consuming.

Cannot Find Good Alternatives​

Initally, I wanted to sell a FOC motor driver for a gimbal motor. If you want to control multiple motors, you probably want to control them with CAN bus because a single microcontroller doesn't have enough PWM pins. I finished designing and testing the FOC motor driver and finally felt ready to sell it. However, I wondered if there are any good gimbal motors suitable for my FOC motor driver and realized that there are not many gimbal motors available on the market.

Working on a Motor Winding Machine​

That's when I decided to build a motor winding machine to wind my own gimbal motors. This would allow me to fix my two broken motors and create new ones for my FOC motor driver. My goal is to convert affordable drone motors into gimbal motors and sell the FOC motor development kit (FOC motor control driver & gimbal motor).
