Concepts of Physics Used in Industrial Machines: Electric MotorsIn order to understand well what machines we need we must know about the concepts of physics used in industrial machines . There are many of these that can be learned without being physical and that will help in a faster selection of industrial machinery.
Concepts of physics used in industrial machines
Law of LorentzThis is the principle that electric motors follow to function . It is a basic principle and explains how forces are created in electromechanical systems, which are the ones that use electric motors. The complete description for each type of electric motor depends on its components and its construction and therefore, the equation changes according to the type.
This law talks about the force exerted by the electromagnetic field and that it receives a charged particle or an electric current. That is, it is the force and follows this equation:
CC / CAThe current is continuous flow of electrical charge passing through a conductor. It does so between two points of different potential and electrical charge and does not change direction with time. That is to say, electric charges always circulate in the same direction. However, in alternating current , they can change. It is one of the main concepts of physics used in industrial machines.
Applying this concept to the different electric motors, we have to:
The DC motor. This type of motor converts electrical energy into mechanical energy by means of a rotary movement. This rotary movement is generated as a consequence of the magnetic field.
The AC motor works by means of electric power. This motor converts electrical energy into turning force by means of magnetic fields .
