However I think it was more to do with the limit of the boost converter and power going in, as I ran some tests and saw voltage drop and it get very hot. I have been running a PWM signal the entire time from slow to fast. I replaced with a beefier buck converter and also put a 100mf cap on the supply end and I've not had a single stall since. I found 4v to be about right. | |

| Jul 30 at 12:09 | comment | added | Gos | If the motor is rated at 3.7V, you should run it at around 3.7V. Or you should know the operating range. But not at 5V and more. I suppose that's the reason of your problems. And I suppose that you should control the speed with PWM or regulating the current. | |
