An electric motor is a captivating rotary device that ingeniously converts electrical energy into mechanical energy. At its core, it comprises an electromagnetic coil winding or distributed stator winding, essential for creating a magnetic field, paired with a dynamic rotating armature or rotor. Through the influence of the rotating magnetic field within the stator winding, an electric current flows through the armature's squirrel cage aluminum frame, causing it to spin under the magnetic field's power. Ingeniously versatile, certain types of these machines can function as both electric motors or generators, seamlessly converting electrical energy into potent mechanical energy.
Working Principle:
Motors are astounding devices, transforming electrical energy into powerful mechanical energy. They achieve this through energized coils, known as stator windings, which create a dynamic rotating magnetic field. This field interacts with a squirrel cage-style closed aluminum frame rotor, generating the magnetic electric rotational torque essential for movement. Electric motors are classified as either DC motors or AC motors depending on their power source. AC motors, predominant in power systems, come in two varieties: synchronous or asynchronous, with the latter having stator magnetic field speed and rotor rotation speed that don't align. Key components include the stator and the rotor, where the energized wire's movement direction within the magnetic field is determined by both the current's direction and the magnetic field lines' orientation. In essence, the operation of an electric motor relies on the magnetic field exerting force on the current, resulting in the induction of rotation.
