Motor Guide-Learning the Basics of the Working of Motors and Tips to Choosing the Right Motor
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. 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 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. As we move on, we first take a look at the points on the working of motors.
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. 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. These uses and applications will see these devices used and found in areas such as in the blowers, machines and other kinds of power tools, fans and you as well see them on pumps. Motors are of varied kinds and types but for the ones that are most common are the brushed and the brushless. But for information, learn of these other kinds and types of motors such as the vibrating motors, the servo and the stepper motors. The DC brush motors are the most popular as they are so simple, inexpensive, simple to control and as well have the highest RPM at 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.
You will have a number of factors that you will need to look into as you look for the right kinds of motors but for the most important ones that you need to ensure are such as the voltage requirements, the torque, the velocity which is gauged by the revolutions in a minute, and the current.
