Good morning Daniel,

You have ever seen a loudspeaker? They have coils and with the voltage/current and a frequency it is swinging and making sound.

A motor does also have coils, it is the same princip by using a voltage and the PWM (Puls With Modulation).

I explain it in detail later, if needed.

Greetings

This explanation is fine for me ... didnt think the coils inside a DC Motor can be used like this =)
