I'm familiar with how an electric motor works, and also familiar with what stall current and free current refers to in an electric motor. I'm also somehow familiar with the notions of energy being transformed from electromagnetic to kinetic and to heat.

I've also reviewed questions like these:

• http://robotics.stackexchange.com/questions/613/what-is-stall-current-and-free-current-of-motors
• Why do electric motors draw current even when they are not moving?

What I'm yet to fully understand is why exactly, from a physics point of view, does the current increase when the motor is stalled, and more intriguingly why does the current drop when the motor is moving.

I'm guessing that the coil resistance increases/decreases when the motor is moving/stalled, but I can't grasp the idea of why does that happen and what the explanation at an electric/electromagnetic level is.

I guess another way to put it's why isn't current always flowing at it's maximum in an electric motor and actually drops when the motor is moving?

thanks!
