The armature is a part of the motor that plays an important role in its operation. It is wound with a number of coils around it that forms a magnetic circuit. This circuit is responsible for the production of flux which in turn develops the required torque. This is the reason why it is considered as the heart of any rotating device because it is the source for the production of flux in any machine. So, let us discuss in detail about the importance of … [Read more...]

The rotating machines function on the same principle of electromagnetic induction those are the motor and the generator. Even though the principle is the same their the output they deliver differs due to the operational difference. This difference in operation is important for the machines to be classified as either a motor or a generator. Similarly, the individual machines can also be classified as ac or dc typed depending on the input and output they … [Read more...]

An Electrical Generator is a machine that converts mechanical energy into electrical energy. This machine is further classified into two other kinds based on the power supply i,e ac and dc. The basic difference name a generator as an ac or dc is its input power supply. If the supply to the machine is single directional then it is Dc and it is vice-versa if it is alternating. The internal operation differs with this input supply. Let us discuss in detail … [Read more...]

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...]
