Default RE: How does a brushless motor work?

Hi
I kind of understand that the controller outputs a voltage that follows a trapezoidal waveform so the current also follows a trapezoidal waveform but with rounded corners caused by inductance, Is this true.
What alters the motors RPM? Is it the frequency of the waveform.
