I need some help designing a project. I need a PCB that will control a brushless 12v DC motor (so 3 phase) from a 12v input. The motor is rated at 15A 12vdc, I need the motor to either be off or run at 100% no variable control. The circuit board will have constant 12vdc source from a battery, ground, and a 12v switched wire that will allow me to turn on and off the system. It basically is a relay that converts from single phase to 3 phase. Can anyone please help me.
