I'm not sure if this is the right place for this post but here it is. I have a buffer motor that spins at 3450 RPM I'd like to do one of two things. Either drop the RMP in half or make it variable speed. I'm attaching two pictures; one of the motor specs and one of what I believe is the starting capacitor. Also a word of warning I understand basic electronic and have put together some kits but I'm no wiz. This isn't as simple as just changing that capacitor is it?
Thanks
