Hello, first time poster though been watching the blogs on YouTube for years
.
I service industrial dryers and recently I've been seeing a new model which has a strange behaviour/fault. No matter what speed the motor is running at, when you switch it off the motor "jolts" as if it is going full speed for a second.
I have attached some images of the control board and a little schematic of the circuit (I've not drawn schematics since high school physics so don't laugh
).
I am wondering if there is something that can be done to modify this circuit so the motor does not jolt when switched off.
Other control boards I work with have choke capacitors which is the only major difference I see with them, but I don't think I know enough to go playing around with the circuit without some guidance
.
Cheers.
