Motor Guide-Learning the Basics of the Working of Motors and Tips to Choosing the Right Motor
To start us off, we need to mention that motors can be found practically anywhere having such a wide array of applications. In this post, there is a deliberate attempt to learning the basics of electric motors, see some of the types of motors and as well some tips to choose the right kind of motors. The type of motor to choose and the specifications are some of the questions that matter most when deciding which type of motor will be appropriate. Moving on, first things first, we take a look at some of the points on how motors work.
Basic physics teaches us that these devices work creating motion by concerting electrical energy to mechanical energy. This force is so generated in the motor in the interaction of a magnetic field and the winding current, AC or DC (alternating current and direct current respectively). The strength of the magnetic field will increase as the strength of the current as well increases and as such lending credence to the conclusion that there is such a direct relationship between these two. Only heed the Ohms law and as such ensure that you increase the voltage so as to maintain the same current in relation to the increase in resistance.
For the uses and applications, nothing can be further from the truth as the electric motors have such a wide array of applications. Some of the well known uses for motors include such as blowers, in machine and other power tools, fans and as well on pumps. There are a wide variety of the types of motors but the most common types 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 DC brush motors happen to be the most common kinds of motors for the many benefits that they have such as being simple, cheap, easy to control and also have the highest torque at quite low speeds. As for their downside, these have only some few shortcomings and these are such as the fact that they may prove to be demanding so much in regular maintenance for the worn out brushes and as well they in a way happen to be limited in speeds as a cause of the heating of the brushes.
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.
