Completely normal, all the ESC's I've ever had make a high pitch sound.

there are magnets and coils in the motor just like in any speaker and you apply a high frequency pulse to them, thus the noise. As you accelerate more and more the noise goes away.

Not the motor, this is completely standard for an ESC.
