I'm trying to modify a VCR so that the big drum that scans the tape spins slower (for an art project...). It's a brushless DC motor that uses a special VCR-specific IC to control it, I believe. The chip is a sanyo LB11885 (http://www.semiconductor-sanyo.com/ds_e/EN7884A_d.pdf" [Broken] datasheet). VCR repair manuals I've read also indicate that there's a control loop regulating the speed of the motor. Is there any way to bypass that, so that I can use a potentiometer to control the drum's speed, or even just reduce it slightly? I've also looked into brushless DC motor controllers for RC stuff, but they are a bit out of my price range.
