An electric motor, as its name implies, is a device which uses electricity to produce a motoring or mechanical output. In other words, most, if not all, devices in our daily lives comprise some form of an electric motor in their works. Although the term motor infers that the device is in motion or induces movement, it is not necessarily the case at all times. The movement assumed to is that within the motor, hidden from plain sight.
How They Work
To have some inkling on what goes into making an electric motor work, it is best to have some basic knowledge on magnets. As taught in elementary science, a magnet is made up of two opposing poles known as the north and south poles. If there is another attraction within close vicinity, both show immediate pull towards one another via their opposite poles. The coinage of the term whereby opposites attract was describing this phenomenon. Concluding this short recap in Physics and English, we proceed to the makings of an electric motor which comprises a few core elements. An electromagnet is a magnet powered by electricity. The magnetic field occurs via a coil of wires through which an electrical current run through the coil. Increasing the number of coils of wires adds to its force.
The second element is a permanent magnet, placed within proximity and surrounding the electromagnet. Once the electromagnet is switched on, a magnetic field is created causing the coil of wires to turn due to an attraction of opposite poles of both magnets. How do electric motors work with a single turn of the coil? Obviously, they don’t. To create a true-blue electric motor, it is essential for the coil to produce a continuous flow of movement gets converted into useful energy. Constant turning happens as the electromagnet’s poles are rapidly flipped and alternated to induce attraction and repulsion towards and away from the permanent magnet’s poles. This then translates electrical and magnetic energy into kinetic energy or motion.
In the makings of an electric motor, there are two kinds of a power source. Most electric motors run on the alternating current which causes the alternating of poles and continuous spinning of electromagnetic coils. Electric motors use direct current supplied by batteries. To produce the alternating poles effect, there is an additional part in each engine to simulate the alternating direction of the current into the electromagnet. If a device requires a fair amount of movement, its electric motor is usually powered by alternating current. Fans, blenders, and trains fall into this category. Direct current is typically sufficient for lesser-powered motors such as notebook fans and hard disks, hand-held vacuum cleaners, and electric toothbrushes.
If you have a motor in your home that isn’t working properly, they are easy enough to repair. Make sure you find the right electric motor components, and you can easily fix it yourself, or use a mechanic to come in and fix it for you. Motors are so prevalent in our society that you should be able to find a repairer fairly quickly, and if it’s simply an electric motor problem, then you can rest assured that it is repairable.
So take a look around you today and take note of the way electric motors make your life a little easier. You’ll be surprised at what you find.
