WebSep 5, 2024 · When a flywheel (not flyback) diode is used this current flows through the diode and dies away on the L/R time constant of the inductive device. In the case of a … Web1. At turnoff the flyback diode will momentarily carry the same current as your motor is consuming. This current will then reduce quickly depending on the inductance and resistance of the motor. You will find a rating in the diode data sheets for non repetitive surge current normally about a 10ms rating. The inductive spike at turnoff should ...

WebIt's because the motor is an inductor and sudden changes in current can cause flyback (high voltages) which is dangerous. The diode also known as the flyback diode which you can search on Wikipedia eliminates that … WebAug 20, 2024 · The idea with the flyback diode is that it doesn't let that generated current "back" into the system, and burn up your MCU. I've seen them in series with a small resistance, to help quickly bleed off any current/voltage the DC motor ends up generating. WebJun 15, 2024 · The motor can be supplied up to 5 amps so all you need is a diode that can handle a peak of 5 amps (not continuous) and has a reverse working voltage that is at least 40 volts (a bit more than 30 volts). A 10 A continuous diode capable of a reverse voltage of 1000 volts is of course perfectly usable but i question why a 1N400x wasn't recommended: - keoghtom’s restorative ointment
