. Conventional cars have engines. From the driver’s seat, very few vehicle owners have more than a passing understanding of what is powering their vehicle or how it works.
. When an alternating current is supplied to the stator, it generates a rotating magnetic field magnetic which interacts with the permanent magnets in the rotor to create a synchronous rotation which produces the torque that turns the wheels of an electric vehicle. The synchronized rotation ensures optimal power conversion, maximizing efficiency and performance in a compact package.
One drawback to these motors is that permanent magnets usually require rare earth minerals, which are expensive and may have sustainability drawbacks due to the way in which they are mined.The rotating magnetic field is formed from the sum of the magnetic field vectors of the three phases of the stator windings.

Electrically excited synchronous electric motors are known for their flexibility and adaptability. They do well in use cases that demand high torque and power, ensuring peak performance across diverse driving environments. They embody adaptability and power while adapting their operational characteristics to the demands of a particular vehicle for optimal performance. BMW uses them to power most of its electric cars.
