Hey folks, I know forum users hate it when people join just to as a question... but hey its Friday afternoon, and I’m having a serious brain f**t, and the boss keeps asking me how its going Disclaimer, i do not play with electronics for a living, and this is like the 3rd circuit I’ve ever tried to make. I didn’t even know what a PWM ment until this morning, but i know what it does, not how it works...
So please bare with.
Goals:
1. variable speed motor
2. be able to change motor direction
3. be able to change direction without having to adjust speed
4. have a override "fast" mode where speed adjustment can be bypassed
Questions:
1. Will this work?
2. Do I need the diode?
3. Should I implement some relays?
4. Is there a better -> cheaper way to do it?
5. Is the PWM gunna shoot 20A at the motor all the time? or will the motor just draw what it needs?
6. The motor is only rated at 16A, but this is very intermittent use...
