An electric motor stands as a marvel of engineering, a rotary electric machine expertly designed to transmute electrical energy into mechanical motion. Its ingenious construction primarily comprises an electromagnetic coil winding or a distributed stator winding, both essential for crafting a compelling magnetic field. At its heart lies a rotating armature or rotor, brought to life by this magnetic field. In a captivating dance, the rotating magnetic field within the stator winding induces a current within the armature's squirrel cage aluminum frame, setting it in motion. Some versatile versions of these machines skillfully toggle between being electric motors and generators, embodying the art of energy conversion from electrical to mechanical prowess.
Working Principle:
Electric motors are awe-inspiring devices that deftly convert electrical energy into mechanical power. They harness the capability of energized coils, also known as stator windings, to generate an enthralling and dynamic rotating magnetic field. This energized field collaborates with a squirrel cage-style closed aluminum frame rotor, yielding magnetic electric rotational torque. Electric motors distinguish themselves as either DC motors or AC motors, dictated by their power source. Among these, AC motors reign supreme within power systems, manifesting as synchronous or asynchronous types, where synchronization of the stator magnetic field speed and rotor rotation speed varies. At their core, an electric motor features two fundamental components: the stator and the rotor. The movement of the energized wire within the magnetic field hinges on both the direction of the current and the orientation of the magnetic field lines. In essence, the principle governing an electric motor is the magnetic field's force on the current, which ingeniously induces rotation.
