| The Transformation of Electrical Energy to Mechanical Energy |
The transformation of electrical energy to mechanical energy is a fascinating and often complicated process, but fortunately, we can simplify things by breaking the problem down into three distinct parts; the generator, the motor, and the transmission. Let’s take a look at how each of these components contributes to the overall process.
Electrical energy
The energy generated from electrical energy is found in both mechanical energy and thermal energy. Electrical energy is converted into mechanical by using a generator that consists of magnets, copper coils, and steel blades. Electrons are pushed through a magnet which creates a magnetic field that spins inside a coil with an axis parallel to an electromagnetic field. This movement produces mechanical force when one part moves against another as it gets closer to alignment with another section. In terms of thermal energy, when high voltage and current flows through wires, resistance and loss occur.
Mechanical energy
When one object is pushed against another, it takes force or energy to move it. This is a type of potential energy because if we were to put that object in someplace where it was motionless (like standing still on a hilltop), then its position is a form of potential energy as well. This can be compared to electricity because when you turn off an electrical appliance, it’s not really off but rather at rest and ready for use at any time. If we measured how much work went into moving something from being motionless to becoming part of our motion, we could say that there is a certain amount of mechanical energy stored within it now. This means that there must have been working done on it in order to create the movement; without outside forces acting upon it, mechanical energy would remain unchanged until acted upon by one itself. In other words, change requires work—and nothing happens without changes taking place!
DC Motor
In a DC motor, an electrical charge moves through wires and brushes to reach a set of electromagnets. The electromagnets attract and repel one another. This movement turns a central rotating rod, which then turns other components (like gears or wheels) with it. The mechanical energy created by DC motors is what makes them useful in everything from toys to spacecraft. The majority of residential electricity in homes across America comes from power plants that run on AC power; however, most home appliances use DC power produced by small DC motors. Your microwave, dishwasher, stovetop, washing machine—all these devices work using DC motors.
In order for an electrical current to transform into motion, we must force electrons to move through a wire to create magnetic fields around coils of wire—this is called Faraday’s Law of Induction.
AC motor
The alternating current (AC) induction motor, also known as a synchronous motor, is an electric motor that uses electromagnetic induction to create rotational motion. It consists of two main parts: a rotating magnetic field and a stationary part with conductors arranged on it. The magnetic field may be produced by either an electrical current or a permanent magnet, depending on the type. The basic concept is similar in principle to that of an electric generator, but the interaction between parts is different. There are two main types of AC motors: asynchronous AC motors and synchronous AC motors.
In an asynchronous motor, rotor poles can turn at whatever speed they want as long as their position changes relative to stator poles.
