Basically, a machine is classified into two types depending upon its operation. They are the generator and the other is the motor. The generator generates electricity while the motor utilizes this electricity. Let us discuss in detail about the generators in this article. An Electrical Generator is a machine that transforms mechanical energy into electrical energy. However, an electrical generator is of two types. They are one is the AC Generator and the … [Read more...]
AC Generator – Construction, Working & Applications
An Electrical Generator is a machine that converts mechanical energy into electrical energy. Depending upon output the electrical generator is classified as AC and DC types. If the output is a unidirectional current or voltage then it is termed as DC generator. If it is alternating, then it is termed as an AC Generator. There is a small constructional difference between the DC type and AC type. In DC, we use split rings for the conversion of Alternating … [Read more...]
DC Generator – Construction, Working & Applications
An electrical generator is a machine that converts mechanical energy into electrical energy. It works on the principle of electromagnetic energy conversion. When a mechanical domain is given to the machine it develops a magnetic field that is further converted into electrical energy. Initially, mechanical energy to the machine is given by a prime mover. Due to this input current passes through the windings which develop the magnetic field. This magnetic … [Read more...]
Slip Ring Induction Motor – Working, Speed Control & Applications
An Induction Motor (IM) is a rotating appliance that works on the principle of mutual induction. An IM is classified into two types depending on the rotor construction. They are squirrel cage type and slip ring type. As we all know that a squirrel cage motor uses a squirrel cage type rotor. A slip ring IM uses some rings consisting of high external resistance in series with the circuit. In this article, we shall discuss what is a slip ring Induction motor, … [Read more...]
Types of Single-Phase Induction Motor with Applications
The main difference between the three-phase and single-phase induction motor is their operation for the large ratings. But, the three-phase motors use the three phases displaced by an angle of 120 degrees whereas the one-phase uses only one phase supply. This makes possible for the three-phase motors to be suitable for operating even the higher rating appliances. However, the characteristics of the three-phase, as well as the one-phase, resembles the same. … [Read more...]
Single Phase Induction Motor – Working, Construction, Applications
Single-phase induction motor is operated by one power phase and used for domestic and industrial uses. The characteristics of a one-phase IM is similar to that of a three-phase. The three-phase is a self-starting motor but a single phase Induction motor is not a self-starting motor as it cannot develop starting torque. Three-phase develops starting torque by means of RMF. An AC motor can be started by means of an external source but it requires more space. … [Read more...]
What is an Induction Motor – Principle, Working & Types
Nicholas Tesla is the inventor of Induction Machines and the AC supply system. He served his lifetime for the invention of this modern technology. An Induction machine is classified as a motor and a generator. Out of which Induction generator has only a limited usage only in power station. But Induction Motor has multiple usages in our day to day life. It is a machine that can be used for both industrial and domestic purposes. Here in this article, we … [Read more...]
What is a Cooling Tower – Types, Working, Applications
Generally, in a steam power plant, boilers are used for the production of steam by heat water. The heated water is converted to steam which in turn converted to Electrical Energy by rotating a turbine. The steam generated after this operation instead of exhausting to the atmosphere can be reutilized. For reutilization, we depend upon the process of condensation. The steam generated is sent to a cooling tower to convert the steam into cold water. The … [Read more...]
Fire Tube Boiler – Types, Construction, Working & Applications
Steam boilers were used earlier for the production of steam in trains. Later on, with the development in the construction of these boilers, these boilers are classified into different types based on the generation of steam. The steam generated should be of high pressure in order to increase efficiency. So, to generate more steam, steam boilers are classified as water tube and fire tube boilers. The water tube boiler generates more steam of high pressure … [Read more...]
Water Tube Boiler – Types, Working, Construction & Applications
Generally, the boiler is an equipment that is used for the production of steam. The steam generated in the boiler is further utilized to drive a turbine attached to a synchronous generator. The synchronous generator converts the mechanical energy of the turbine to electrical energy. This generated energy is supplied to the bus bars further it is transmitted to different areas. These boilers are classified into different types among them water tube and fire … [Read more...]
