What is the function of stator winding?
It is the stationary part of a rotary system, found in electric generators, electric motors, sirens, or biological rotors. The main use of it is to keep the field aligned. It is opposite to the rotor or armature and where the field windings are in a motor or generator.
What is stator used for?
In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.
Which type of connection is applied for stator?
For the three-phase motor, the stator winding has two connection methods: angular connection and star connection.
What is the connection of winding in a stator?
A three-phase set of stator windings is inserted in slots in the stator iron. These windings may be connected either in a wye configuration, normally without external connection to the neutral point, or in a delta configuration.
What are the two types of stator windings?
Based on the motor winding connection, armature windings are classified into two types which include the following.
- Lap winding.
- Wave Winding.
What are the parts of a stator?
The stator in an AC motor consists of a core of thin, steel laminations and coils of insulated wire inserted into it, which are called field windings and are connected directly to the power source. When current is applied, the two together become an electromagnet.
How is a stator constructed?
The stator core is built up of thin punched laminations of electrical grade steel, which are commonly called “punchings.” They are segmented, meaning that 12 to 24 punchings are laid side-by-side to form a complete 360° ring, comprising one layer.
What is stator winding resistance?
The stator winding dc resistance of a three-phase induction motor is measured by connecting a dc voltage source across two stator terminals. No induced rotor voltage can occur under de stator excitation and hence the resistance ‘seen’ by the dc voltage source is the stator de resistance.
Which winding is used in stator of the induction motor?
The winding wound on the stator of three phase induction motor is also called field winding, and when this winding is excited by three phase ac supply, it produces a rotating magnetic field.
What are the 3 different types of stator windings?
Three types of stator windings were considered in the analysis: concentric single layer winding, concentric double layer winding and fractional concentric winding.
What type of winding is generally used for the stator?
Explanation: The double layer wave winding is generally used for stators.
