It contains a number of windings whose polarity is changed all the time when an alternating current AC is applied. This makes the combined magnetic field of the stator rotate. All stators are mounted in a frame or housing. The stator housing of motors is mainly made from aluminium for motors up to 22 kW, while motors with higher outputs have cast-iron stator housings. The stator itself is mounted inside the stator housing.
It consists of thin, stacked laminations that are wound with insulated wire. The core contains hundreds of these laminations. When power is applied, an alternating current flows through the windings, creating an electromagnetic field across the rotor bars. The alternating current AC makes the magnetic field rotate. The stator insulation design is classified. Stators with two, four and six poles are the most commonly used in connection with pumps, because the speed determines the pressure and the flow.
The stator can be designed to handle various voltages, frequencies and outputs and a varying number of poles. It is a mechanical type of rotating system. The rotor like an arbitrary can be a three-dimensional rigid device. It can be adjusted in space by using three angles called Euler angles.
The linear type is a special rigid type that uses simply two angles to explain. For example, in the diatomic molecule, there are many general molecules that are there with three-dimensional like water ammonia or methane. Here water is asymmetric type, ammonia is the symmetric type, and otherwise, methane is a spherical type. It is the rotary part in the squirrel cage induction motor. It is a kind of AC motor. It includes steel laminations with a cylinder shape.
The conductors like copper otherwise aluminum are fixed on its surface. The terminals of these windings are taken out to connect with the three slip rings along with brushes on the shaft.
The frame supports the core of the stator and protects their three-phase winding. The stator core carries the rotating magnetic field which induces because of the three-phase supply. The rotor is situated inside the core of the stator. Squirrel cage and the phase wound rotor are the types of the rotor. The rotor winding is excited by the DC supply. The field winding induces the constant magnetic field in the core of the rotor.
Basis for Comparison Stator Rotor Definition It is a stationary part of the machine It is the rotating part of the motor. Parts Outer frame, stator core and stator winding.
The stator is the static part of the motor. The main function of the stator is to generate the rotating magnetic field. The stator frame, stator core and stator winding are the three parts of the stator. The stator core support and protect the three-phase winding of the stator.
High-grade silicon steel stamping makes the core of the stator. The rotating part of the motor is known as the rotor. The rotor core and the rotor winding are the part of the rotor. The winding of the rotor is excited by the DC supply.
