How does an induction motor work? In electric cars, the induction motor is also often referred to as an asynchronous electric motor. Both names reveal part of the operation. A rotating magnetic field is generated in the current conductors of the fixed part (the stator) of the motor. This field in turn creates induction in the moving part (the rotor) of the motor. The Lorentz force resulting from this induction ensures that the rotor can turn. At least, as long as there is a speed difference between the rotor and the rotating magnetic field (hence aynchronous). As soon as the rotor spins as fast as the magnetic field, the induction collapses and the Lorentz force disappears. In short: torque is only generated when the rotor and the magnetic field do not rotate synchronously, i.e. rotate asynchronously. That sounds complicated, but is it really?
