Motor Guide-Learning the Basics of the Working of Motors and Tips to Choosing the Right Motor
To begin with, let’s mention the fact that motors have such a wide array of applications and as such you may just reckon the fact that you may come across them anywhere. In this guide, an attempt has been made to get the basics of the electric motors, the varied types available and as well the tips to choose the right kind of motor. 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. Before we progress, some points on how motors work will be first addressed.
From elementary physics class, we learn the fact that these devices work by converting electrical energy into mechanical energy as such creating motion. 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.
Looking at the applications, it suffices to say that these will be used in a wide array of places and application areas. Among these uses and application areas we have such as on blowers and power tools, machines, fans and as well you see them used 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.
