Armature-Rotor Assembly

An armature-rotor assembly refers to the combination of an armature and a rotor in an electric motor or generator.

The armature is the stationary part of the assembly, typically made up of a core made of laminated iron or steel. It is wound with multiple coils of wire, known as windings, which are connected to a power source. When an electric current flows through the windings, it creates a magnetic field.

The rotor, on the other hand, is the rotating part of the assembly. It is typically made up of a shaft and a set of conductive bars or coils. The rotor is placed inside the armature and is free to rotate. When the armature windings create a magnetic field, it interacts with the magnetic field produced by the rotor, causing the rotor to rotate.

The armature-rotor assembly is a crucial component in electric motors and generators as it converts electrical energy into mechanical energy (in the case of motors) or vice versa (in the case of generators). The rotation of the rotor generates mechanical power, which can be used to drive machinery or generate electricity.

Overall, the armature-rotor assembly plays a vital role in the operation of electric motors and generators, enabling the conversion of electrical energy to mechanical energy and vice versa.
