I have a good Fluke meter, and actually a DS203 oscilloscope that I have used once on a project. Would it be able to test the PWM waveform? It’s pretty basic, but it does have 2 channels. I’m fairly fluent in some aspects of electronics, but not using an oscilloscope. So if it’s out of my league that’s ok. If it’s something I could do, I’d enjoy learning about it. If you knew of some good tutorials on how to test the mosfet with one, I’m buying extra mosfets for the ones I accidentally smoke. LOL
- Probably okay for this.
- Sounds like you are on the right track !
Your big lithium battery could probably do a 1000 amps for 30 seconds before exploding if there was a short circuit. Please be sure to have a fuse as close to the battery as possible. 30A if that's the most for your motor. When starting the motor, start with a low pulse width to avoid high current when starting. You should start using your scope just on a signal generator at first so that you get to know the controls and triggering to lock the waveform. Once you have mastered it you will find it very useful
Thanks. I got a 60A battery post fuse.
I think I’ll have some spare time that I’d like to learn about testing that mosfet with my scope.
