I'll try little experiment on deck which has powers by double supply voltage ~±14v. I make this small circuit to supply small motor of CD ROM door's motor it had used as like capstan motor. The risk here that i can got the big noisy distortion by brushes of the motor... Originally it's was BLDC Akai's motor with hall sensors and coils magnetic drive. Is itimpossible that schematic work if it's not able sedition to fix BLDC?!
