I have this dc motor which I've connected to 3 supercapacitors (2.7V and 80F each).
http://www.ebay.com/itm/1-24-H-R-Lightning-Motor-40-000-rpm-NEW-/221125272985
Whenever I have the combined voltage of the supercapacitors more than 5.5V, I get something like this:
I'm using a 5-volt dc relay to isolate the motor from the circuit. The switch of the relay is programmed to close for 900ms, and then open to stop the motor from moving.
The resistance of the motor is roughly 1 ohm. When I have the voltage lower than 5.5V, the car moves fine.
Anyone knows what causing this u-turn?
Thanks in advance.
