How Does an Electric Car Engine Work – Electric cars are powered by an engine technology that offers new experiences in terms of fuel efficiency, environmental awareness and performance. Familiar with most electronics, from washing machines to small fans, these electric motors emerge as part of a more efficient working principle in automobiles.

What Are the Components of an Electric Car Engine?
In order to better understand the working principle of electric vehicles, it is useful to know what the parts in the engine do. As it is known, there are no mechanical parts in the electric car engine. There are two main components in this type of motors, which obtain motion energy by creating an electromagnetic field: the stator and the rotor.
The stator, which is briefly defined as the static and non-moving part of the electric motor, is a component responsible for creating a rotating magnetic field. It consists of parts such as stator core, stator frame and coil. The stator core, which is produced by laminating high-quality silicon steel, functions to protect the coils through which electric current is passed. The stator coils, on the other hand, consist of thousands of conductive wires responsible for creating an electromagnetic field.
The rotor, which is the moving part of the electric motor, has an important role in the conversion of electricity into kinetic energy. This part, which is placed inside the annular stator core, has conductive rods on it. The electromagnetic field produced by the coils in the stator passes over the conductor wires of the rotor and causes this moving part to rotate. As the rotor rotates, it also moves the cogs and gears connected to it, thus providing kinetic energy.
How Does an Electric Motor Work?
Electric motors, which have fewer components than internal combustion engines, have a simple working principle.
The working adventure of an electric motor begins with the transmission of the energy stored in the battery to the motor.
Before the direct current in the battery is given to the motor, it is sent to the control unit and converted into alternating current.
The electric current transformed in the control unit is first sent to the stator part of the motor.
There are three separate pairs of coils, which are located on the inner walls of the stator and consist of conductive wires.
The electric current passing through the pairs of coils lined up against each other creates an electromagnetic field after a three-phase tour.
The electric current generated in the fixed stator passes through the conductive rods on the rotor and causes the part to rotate.
The rotation of the rotor moves the trolley gears, creating the mechanical energy needed for driving.
How Do Electric Vehicles Charge Themselves?
In diesel and gasoline powered cars, the energy needed for starting and operating other electronic equipment is provided by the battery. The charging of the batteries with reduced power is carried out by the alternator, which converts mechanical energy into alternating current while the vehicle is in motion. So how does the battery charge itself in electric vehicles that do not have any alternator?
In electric vehicles, the conversion of kinetic energy into electrical energy is carried out by the engine. Charging the battery and the engine acting as an alternator begins when the accelerator pedal is released. The magnetic field created by the stator stops when the driver releases the throttle. This causes the rotor to spin faster in the opposite direction of the current magnetic field. In electric vehicles, when the foot is taken off the gas, a slowdown is felt as if the brake is applied.
Since this energy conversion in electric vehicles does not occur without loss, the battery must be constantly recharged at charging stations. It is a fact that this process, which sometimes takes hours, puts electric cars at a disadvantage. However, with hybrid technology, another member of the electric vehicle class, this disadvantage has been largely eliminated. Because hybrid cars are powered by an electric motor that does not need external charging. The electric motor, which works in harmony with the gasoline engine, can charge itself while driving.
