The Fundamentals on the Working of Motors and How to Select the Right Kind of 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 increases as well. 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.
Looking at the applications, it suffices to say that these will be used in a wide array of places and application areas. 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. 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. They only have some few disadvantages such as the fact that they will call for regular maintenance such as the need to replace the worn out brushes and the bit that they may happen to be limited in speed as a cause of the heating of 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.
