According to classical physics, if I take an electric motor with a resistance of 1 ohm, and run 10 volts through it, 10 amps of current will run through it. But through experiment, a lot less current will run through the motor, an average brushless motor with a resistance of less than a milliohm will draw only a few amps when spinning, even at high voltages.
At the same time, if I take the same motor, run the same voltage through it, and put a load on the motor, it will draw a lot more current.
Does this have something to do with the presence of permanent magnets near the coils or is there another phenomenon going on here?
