Variable DC Motor Control

[tuttuttut]

Upon further investigation, I read here:

1N4007 or MBR340 for Flyback ?

You didn't mention if the motor is being PWM'd or on continuously. If PWM'd I would use the MBR340 + a 0.01µf ceramic capacitor. Reasoning: Assuming your switching times are fast (i.e. the time it takes to transition from On to Off and vice versa. The 1N4007 is not good because it will conduct in the reverse direction for a short period of time when switched quickly (Google reverse recovery time and /of look here Reverse Recovery Time of a diode) The 0.01µF capacitor is to reduce voltage noi…

Not fully understanding... I believe this to be a snubber network (???)

I found this to look useful:

RC snubber circuit design and calculations for inductive loads

Any idea what a typical 775 frame motor has for inductance please?

Got lots to learn tonight...

Any suggestions for typical values used?
