I would like to ask a question related with induction motor
Whenever I switch ON & OFF a motor, a small voltage (3-8 V) produced at the metal surface where the motor is attached. I figure out this small voltage by using an oscilloscope. The voltage lasts in millisecond.
I wonder if this small voltage produced when switching ON & OFF the induction motor by using any protective device or component can be eliminated.
The circuit contain only push button, switch button (to change motor direction) capacitor and the induction motor itself
Anyway this is the motor I'm using right now:
Thank you for the response
