I have this 12V DC Gear motor, but I can't find much info about it online. The reason I have bought it was that I found this particular motor across several tutorials on how to build an RC car.

I will be using the L298N Dual H-Bridge Stepper Motor Driver to control four of these motors, and while I wait for it to arrive, I've started working on the software. After some research online, I have determined that the PWM frequency to be used varies depending on what motor/motor driver is being used.

That said, I would like to ask people who have used hardware similar to mine what PWM frequency should I use to use these motors optimally?

Thank you in advance.

    [Good reasons to think carefully before you use the L298](https://electronics.stackexchange.com/questions/108686/l293-l298-and-sn754410-h-bridge-drivers-on-low-voltage-power-supply) – Andy aka Jul 19 '18 at 09:10
  • Probably as low as you can live with to minimize switching losses. – winny Jul 19 '18 at 10:37

A frequency around 200-400Hz is fine. You have a larger range of duty cycle at low frequency.
