Need help with a brushless motor?
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.

You need to drill down and search into the CD-ROM motor rebuild links. There is a whole community of RC plane makers who build CD-ROM foamies and wire their own motors.
If you haven't done any controller designs yet, I suggest doing a brush motor controller first to get some basic principles down. This is a hobby brushless controller:
as you can see from the bottom scope traces the 3-phase timing signals are quite sophisticated and require understanding of fast switching transistors controlled by a brushless controller chip.
