Ok so I have a dc brushless motor that apparently after some researching has three coils and a center tap, meaning there are four wires coming out of it.
I tossed the original control circuitry (it was a hard drive) as it did not work. How would I get this to work with an Arduino? I was thinking that I could use
one of my SN754410 drivers to supply the voltage/current and have the Arduino turn on/off the bridges on the SN.
So would I apply ground to the center tap, and turn on the coils one at a time in short pulses to get rotation? Anyone have any snippets of code or tips on messing with this kind of motor?
And where should the flyback diodes be? From the outputs of the SN to the coils of the motor?
Thanks!
