An electric motor is a sophisticated rotary electric machine, masterfully converting electrical energy into mechanical power. Its core components include an electromagnetic coil winding or a distributed stator winding, both crucial for generating a potent magnetic field. This magnetic field interacts with a rotating armature or rotor. Under the influence of the stator winding's dynamic rotating magnetic field, current flows through the armature's squirrel cage aluminum frame, causing it to rotate powerfully. Notably, some of these versatile machines function either as electric motors or generators. In essence, it's a marvel that adeptly transforms electrical energy into mechanical prowess.
Working Principle:
Motors are exceptional devices that ingeniously convert electrical energy into mechanical force. They utilize energized coils, known as stator windings, to create a dynamic rotating magnetic field. This field interacts with a closed aluminum frame rotor, designed in a squirrel cage style, producing impressive magnetic electric rotational torque. Electric motors are broadly classified into DC motors and AC motors, based on their power sources. AC motors are predominantly employed in power systems, available in synchronous or asynchronous varieties (the latter where the stator magnetic field speed and rotor rotation speed do not match). The fundamental components of an electric motor are the stator and the rotor. The directionality of the energized wire's movement within the magnetic field is determined by both the current's direction and the orientation of the magnetic field lines. Essentially, the working principle of an electric motor is rooted in the magnetic field exerting a force on the current, thereby inducing robust rotation.
