I have a small raspi controlled remote control car using regular drone motors such as these ones and tried using this 60w power supply unit that can be downregulated to 3v and connected everything using two drv8833 motor drivers. However, the spikes in power drainage generated from one motor alone seem to be enough to drain the entire amperage of the circuit, in spite of each motor only consuming 0,15a. Is there a reason for this?
It's possible that there is some additional resistance when the motors start up causing them to drain more than the specified 0,15a, I am not using any gears but the car itself is very light so I don't think the spike in amperage drainage justifies all the other motors completely stalling when the power source is said to provide 60W.
The current limit for the DRV8833 is 2A, I am using two of those modules with each having two motors connected to them.
Is there a good solution to this problem? I tried placing a 3.300uF 6.3V capacitor around the motor driver but am still having problems with only one of the motors actually starting up
