Thank you all in advance for sharing your knowledge and expertise.
My project consists of a BLDC motor (G160) driving a crankcase vacuum pump to maintain a constant vacuum in the crankcase.
I have an ESC rated for this motor but it’s the signal I’m having trouble with.
I have an aftermarket Holley ECU with programmable 12vdc pwm+ or pwm- outputs - frequency range 1-1000Hz and programmable duty cycle.
I have tried a simple voltage divider with resistor and shotky diode - didn’t work.
Tried an automotive solid state relay - didn’t work.
Hopefully someone here has some ideas I can implement that will make this thing work.
