Any idea where I could find such a thing on the internet?

PC cooling fans and ceiling fans are not DC motors. They are AC motors. I know lots of places where you can find a AC motor and controller which will have a DC input to the controller.
An electric motor with outer rotor is a type of electric motor where the rotor (the rotating part of the motor) is located on the outer surface of the motor. This is in contrast to an electric motor with an inner rotor, where the rotor is located inside the motor.
An electric motor with outer rotor works by using the interaction between a permanent magnet rotor and an electromagnetic stator to generate rotational motion. The outer rotor is connected to the motor's output shaft and rotates as electricity is passed through the stator, creating a magnetic field that interacts with the rotor's magnets to produce rotation.
One advantage of an electric motor with outer rotor is its compact and lightweight design, making it suitable for use in small and portable devices. It also has a high power-to-weight ratio, meaning it can produce a lot of power while remaining lightweight. Additionally, the outer rotor design allows for efficient heat dissipation, resulting in improved motor performance and longevity.
Electric motors with outer rotor are commonly used in various industries, including robotics, aerospace, and automotive. They are also used in household appliances, such as blenders and electric fans, as well as in power tools and electric bicycles. Their compact size and high power output make them ideal for use in applications where space is limited.
Compared to other types of electric motors, an electric motor with outer rotor has a higher power-to-weight ratio and a more compact design. However, it may have lower efficiency and torque compared to other types of motors. The choice of motor type depends on the specific application and its requirements.
