For analysis [oscilloscope wave form] purpose I am running a BLDC motor at 9Vdc. Power Sorce is giving the constant DC voltage to BLDC Motor. But whenever I am disconnecting the voltage there is a spike seen in voltage (Approx 15.4 v).
- What is this spike?
- If its Back EMF why its not showing in reverse direction?
Refer the Picture (I am Disconnecting the input by disconnecting the Ground Manually)
