How does the BMW i4's electric motor function?

I am curious how the electric motor in the BMW i4 works. Can you explain the technical aspects of its functionality and how it differs from a traditional combustion engine?

The BMW i4's electric motor uses a series of magnets and copper wire to create a rotating magnetic field. When electricity is passed through the wire, it creates an electro-magnetic force that spins the motor. This creates movement in the wheels and propels the car forward.

The electric motor in the BMW i4 is much more efficient and environmentally friendly than a traditional combustion engine. It produces no emissions and has a smoother and quieter operation.

In terms of maintenance, the electric motor in the BMW i4 requires much less upkeep compared to a combustion engine. There are fewer moving parts, reducing the chances of mechanical failure and the need for frequent oil changes.
