How is an electric motor classified?

Electric motors are classified largely by their power source, construction, and operational features. This classification is crucial because it helps determine the motor's suitability for various applications and environments.

For instance, electric motors can be powered by alternating current (AC) or direct current (DC), leading to significant differences in their design, performance, and the types of applications for which they are best suited. Additionally, the construction of the motor, such as whether it is a brushless or brushed motor, and operational features like speed, torque, and efficiency ratings further influence how motors are categorized.

While factors such as color, size, housing type, or frequency of operation may have some relevance in specific contexts, they do not fundamentally define the classification of electric motors in the same systematic way. Therefore, understanding the broader characteristics of power sources and motor design is essential for effective classification and application in real-world scenarios.
