Electric motors convert electrical energy into mechanical energy, using the principles of electromagnetism. When an electric current flows through a motor's windings, it generates a magnetic field, which interacts with a stationary magnetic field to produce motion. This motion is what powers electric vehicles, fans, and many other devices.
AC (alternating current) motors use a rotating magnetic field to produce motion, while DC (direct current) motors use a fixed magnetic field. AC motors are commonly used in industrial applications, while DC motors are preferred in applications where precise speed control is required.
