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. As we move on, we first take a look at the points on the working of motors.
From elementary physics class, we learn the fact that these devices work by converting electrical energy into mechanical energy as such creating motion. 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. 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.
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 are of varied kinds and types but for the ones that are most common are the brushed and the brushless. 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 are the most popular as they are so simple, inexpensive, simple to control and as well have the highest RPM at low speeds. 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.
