Hello! i need help with a brushless motor from a HDD. I have very little understanding of how they work, i want to create a controller for this motor, something like a throttle system for an rc car. this is an experiement for me, im sure the motor is not ideal for RC cars but i want to learn about them anyway. i cant until i learn more about the motor. It has four inputs, two ground and two Vin leads. does anyone know the name and type of motor this might be so i can start researching it. PS. i am in school to learn so i dont just want to by a speed controller. i want to learn and create my own.
