why don't electric cars use hub motors?

Electric cars, like all vehicles, require a system for converting the electrical energy stored in their batteries into motion. One type of system that is commonly used in electric vehicles is the hub motor, which is a type of electric motor that is located within the hub of a wheel. While hub motors have several advantages, they are not commonly used in electric cars for a variety of reasons.

One reason why electric cars don't typically use hub motors is that they are less efficient than other types of electric motors. Hub motors are limited in their ability to deliver power because they are small and have limited space for cooling. This means that they can become overheated and lose efficiency when subjected to high levels of stress, such as when driving up a steep hill.

Another reason why electric cars don't use hub motors is that they can be difficult to package within the vehicle. Hub motors are typically located within the wheel hub, which can make it challenging to design a suspension system that is both comfortable and capable of handling the weight of the motor. In addition, hub motors can be noisy and may produce vibrations that can be uncomfortable for passengers.

Finally, hub motors are generally not as powerful as other types of electric motors, such as those that are located within the drivetrain of the vehicle. This can limit the performance of an electric car that is equipped with hub motors, particularly when it comes to acceleration and top speed.

In summary, while hub motors have some advantages, they are not commonly used in electric cars due to their lower efficiency, packaging challenges, and limited power output. Other types of electric motors, such as those located within the drivetrain, are typically preferred for use in electric cars due to their superior performance and reliability.
