Introduction of electric motors and types

 You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned.

An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are electromagnetic-based.


Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused.

Types of Electric Motor

Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-phase), and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial use.

AC Motors

The AC motor is one of the types of electric motors that uses current with an alternating direction. These motors are not as easily speed-controlled as DC ones; however, with a bit of power penalty, one can use AC motors with variable frequency drives to have a better speed control.

Everything you should know about HVAC

What is HVAC? What do you know about it? What is its use? In this article, we will take a closer look at HVAC, so join us to get the answers to these questions and any other questions about HVAC. The importance of HVAC Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of  mechanical engineering , based on the principles of thermodynamics, fluid mechanics and heat transfer. As was mentioned earlier, an  HVAC system  is intended for thermal control of areas as well as comfort for occupants. Temperature is factor that affects the performance and health status of many systems. Take the case of a server room temperature as an example for which high temperature adversely affects the system’s reliability and operation of the servers is a great source of heat ge...

Introduction of Wind Turbines and its types

Image
  Due to the high consumption of non-renewable resources and the possibility of their depletion, turning to renewable energy sources is very important. One of these energies is wind energy, and a device called a wind turbine is needed to convert wind energy into electricity. In this article, we will introduce wind turbines and their types.  A wind turbine is one of the types of turbines used to convert wind kinetic energy into electrical energy. Wind turbines are made in two types with the horizontal axis and vertical axis. The first wind turbine to generate electricity was a battery charger built in July 1887 by a Scottish engineer named James Blyth. A few months later, American inventor Charles Francis Brush built the first automatic wind turbine to generate electricity in Cleveland, Ohio. In 1908, 72 wind turbines were used in the United States to generate electricity (between 5 and 25 kW). Wind turbines are manufactured in a wide range of sizes, with either horizontal or v...
