Answer by Simon Fitch for DC motor voltage kickback when turning off
The spike is caused by motor winding inductance, as you noted. It happens when you try to open the motor's current path, causing that path to become very high resistance. The winding's inductance tries...

The fast spike it the effect of the inductance of the motor windings,The slow decline is the effect of the spinning motor is acting as a generator.

I'm not seeing your time scale, but there would normally be an inductive 'kick' followed by the back-EMF of the motor itself as the armature slows. It acts as a generator and the inertia maintains some...

I am answering without seeing your motor circuit but I really need to see it to be sure.The normal inductive flyback voltage spike from interrupting current through a motor should send the voltage...

DC motor voltage kickback when turning off
newbie here.I'm having some problem with my DC motor circuit.As you can see from the image above, voltage does not drop off quickly when it's turned off.I understand that the sudden spike is due to...
