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...]

The steps began for the introduction of induction motor in the year 1892. Earlier it was made to run under 60 HZ power supply in 1893. This was made practically possible by Westinghouse. Later investigations have been conducted to work these type of motors under two-phase supply. The multi-phase supply produced much better advantages than single-phase. The disadvantage of one-phase is, it cannot self-start while the three-phase motor can self-start. The … [Read more...]

The operation of the Single-phase induction motor can be done through a single power phase and used in domestic as well as industries. The main characteristic of this kind of motor is the same as that of a three-phase. This motor starts automatically (self) but a 1-phase Induction motor will not start automatically because it cannot expand starting torque. 3-phase expands starting torque through a rotating magnetic field. An AC motor starts through an … [Read more...]

Induction motor is a machine that simply operates on the induction type principle. It was invented by the scientist Tesla who earlier conducted several experiments on the working of the alternating current systems. Later, several experiments have been done to improve the performance of this type. This led to the inventions of the induction type of generator. But this type has limited access due to some of the cons than the pros of this generator. However, … [Read more...]

An electrical generator is a machine that is operated similar to operations performed by other machines. The main important function that it does is generating power. For this to occur, any machine requires a field that is able to develop some rotating field. This field is able to develop some torque that rotates the inner rotating part. For the production of this field, the employment of winding plays a key role. The field winding is placed on the stator … [Read more...]

How do power plants supply current to hundreds of houses? they even don't utilize high capacity batteries. But this can be done by connecting a spinning a turbine to an electrical generator.  Some power plants use extremely hot steam that blasts over the turbines as well as turns it or else uses the energy of the dropping water. one more example is windmills. The fundamental idea is that if you use an electric wire &  move up or move down within the … [Read more...]

Normally, when a flow of current is there in a conductor then there is always a query whether it is a neutral otherwise a phase. For this, an electric tester is used to check the wire. For instance, when we check the two terminals of the batteries, one acts like a positive and the other one works like a negative terminal. It is known as a DC supply. But here, the flow of current includes only single way which does not rotate. In AC supply, the direction of … [Read more...]

The first starter was created by Coleman in 1903 he is an American scientist. Later, in 1911 Kettering and Henry M. Leland further conducted experiments on the starter. In 1911, they invented an electric starter that can be used to start the electric machine. This motor is simply considered as the starter motor which is used to give power to the engines in vehicles. The electric starter finds its application mainly in the case of the automobile industry. … [Read more...]
