ARMATURES Meaning and
Definition
-
Armatures are essential components in electrical machines, such as motors and generators, that enable the conversion of electrical energy into mechanical energy. Specifically, an armature refers to the central part of a machine that rotates within a magnetic field.
Typically made of ferromagnetic materials, such as iron or steel, armatures consist of a core and a winding. The core is formed by stacked laminated sheets to minimize energy losses due to eddy currents. The winding, usually made of insulated copper wire, is wound around the core and carries the electrical current that generates the magnetic field in which the armature rotates.
The primary function of armatures is to produce a rotational motion by interacting with the magnetic field generated by other electrical components, such as stator windings or permanent magnets. When an electric current passes through the armature's winding, it creates a magnetic field that interacts with the stationary magnetic field, resulting in a force that causes the armature to rotate. This rotation is then transferred to other mechanical components, such as shafts or gears, to perform useful work.
Armatures are crucial for various applications, ranging from small household appliances to large-scale industrial machinery. They are designed according to specific requirements, considering factors like voltage, current, power, torque, and speed. Due to their fundamental role in electrical machines, armatures are subject to precise engineering and manufacturing processes to ensure optimal performance and efficiency.
