Given the fact that motors are used in quite a number of places, it is as such a fact as well that you will come across motors in a number of places. This article has taken a particular emphasis learning the basics of electric motors, highlighting some of the types of these devices and the things to consider when choosing the right kind of motors. The motor type and the specifications are some of the most important questions that you need to answer as you decide the right kind of motor for an application. Moving on, first things first, we take a look at some of the points on how motors work.
As per the lessons from basic physics, we get the idea that motors create motion by converting electrical energy into mechanical energy and this is the precise point in their operations. The force herein is produced by the interaction of the magnetic field and the rotating AC or DC. The strength of the magnetic field will increase as the strength of the current increases as well. One law that you need to bear in mind is Ohms law and as such you need to ensure that you increase the voltage so as to maintain the same current even as you have an increase the resistance.
Considering the uses and applications, you will appreciate the fact that the electric motors have such a wide array of applications and uses. Some of the well known uses for motors include such as blowers, in machine and other power tools, fans and as well on pumps. Motors come in a wide range of types but the most common ones are the brushed and the brushless motors. However just for the mention of, these are some of the other kinds-the vibrating motors, the servo motors and the stepper motors. The most common kinds of motors are the DC brush motors and will be found in a number of appliances for the benefits that they come with such as the fact that they are simple to assemble, easy to control, rather inexpensive and as well have the highest torque at low speeds of revolutions. Their only downsides may be in the cases such as the fact that they may call for regular maintenance such as the need to replace the worn out brushes and may be as well limited in speed as a result of the heating up of the brush.
There are a number of factors that you need to consider when choosing the right motor but the most important ones are such as the voltage requirements, current, the torque, and the speed/velocity measured in the revolutions per minute.
