hello, can we overfly the 6v #4784 engine to 9v on short durations, using your 9V Step-Up Voltage Regulator U3V40F9?
Hello.
While the #4784 gearmotor is intended for use around 6V, in general, these kinds of motors can be used at voltages above and below their nominal voltage. Higher voltages will result in higher speeds and more torque, but they can start negatively affecting the lifetime of the motor, and they can also put the motor at higher risk of catastrophic failure when exposed to excessive loads.
The current draw is also proportional to the operating voltage, so at 9V the maximum current draw of the #4784 gearmotor] is approximately 2.4A. Whether or not the U3V40F9 regulator can handle the motor will depend on how you are running it and what input voltage you’re using, but you can get a general idea by looking at the “Maximum Continuous Output Current” graph on it’s product page.

Thank you very much, I power them with a lipo 2s of 8.2V and I thought that it could stabilize the voltage when the battery is discharged, am I right?
Yes, the regulator will output a stable 9V as the battery voltage drains.

Yes, you can, but be careful. Overvolting a 6V motor to 9V for short bursts is fine, but too long can overheat or damage it. Monitor closely!
