    Hello all i want to make a basic BLDC driver thats based on the output of about 60amps and from 7v up. I want it to be very simple and work with a basic push switch so when the connection is active the motor will spin at its top speed. Ive got a basic idea of what i want i will attatch a picture of the type of thing i was planning. Any advice is very welcome.

    Why do you need to be restricted to +7v?
