* Energy Source: Electric motors are powered by electricity, not combustion like internal combustion engines.
* Operation: Electric motors work by using magnetic fields to create torque, which rotates a shaft. This process doesn't require air for combustion or cooling.
* Cooling: While some motors might use air for cooling purposes, it's not a requirement for their basic operation. Many motors use other cooling methods like fans or heat sinks.
Exceptions:
* Brushed Motors: Some older, brushed electric motors might need a small amount of air to help with commutation (the process of switching the direction of current in the coils).
* Air-Cooled Motors: Motors designed for high power applications might use air cooling for efficient heat dissipation, but this is an add-on to the main operation.
In summary, while air can be used for cooling some electric motors, it's not a fundamental requirement for their operation.
