How does an Electric Motor work? (DC Motor)
Jared Owen・2 minutes read
Electric motors are found in various household devices like toys, fans, toothbrushes, and hairdryers, involving the basics of electricity and magnets. The structure of an electric motor includes an armature in the middle, surrounded by permanent magnets on the sides, with methods like adding more wire loops and increasing electricity flow to boost torque and speed.
Insights
- Understanding electric motors requires knowledge of basic electricity principles and magnetism, as they are fundamental to how these devices operate.
- By manipulating the interaction between electricity and magnets, such as creating electromagnets and reversing polarities, the functionality and efficiency of electric motors can be significantly improved.
