Working Principle of Stator

Let us understand the working principle behind a stator

Stator

  • The stator is connected to a three-phase power supply that supplies power to the motor at different intervals depending on the phase.
  • When the stator receives the power, it generates a magnetic field. This rotating magnetic field is carefully designed depending on the need of the device for example it solves different purposes in motor, generator, and levitation devices.
  • When the current carrying conductor i.e. armature is present in the magnetic field, it experiences a force that causes it to rotate.
  • The rotation of armature is responsible for the current generated in the coil. This is how the magnetic field is used for current generation in motor.

Electronic communication involves the use of different components, each needed for a different purpose. One such device is a stator which forms an essential part of the motors used in everyday appliances. In this article, we will study stators and their categorization based on their use. We will also discuss the diagram of a stator to ensure better conceptual clarity of the working of the stator.

The later parts of the article will cover the components of the stator and the design of the stator made using these components. Once, we have covered the basics of stators, we will shift towards the advantages offered by a stator and how are they used in everyday appliances. The last section will talk about the limitations of stators and will conclude with some frequently asked questions.

Components and Construction of Stator

Outer Frame: The outer frame is a base that is used to provide support to the whole setup of the motor. The stator is usually a metallic or a plastic case that has high tensile strength. Core: The core is used to measure and handle the unequal magnetic field in the motor. This process is used for generating eddy current and managing the hysteresis losses. The core is attached to the frame for support and connections in the core are made using stampings at different points in the frame. Windings: The windings are present around the core to provide the necessary power supply to the core. The windings can come in various designs like three-phase or four-phase designs depending on the motor requirements. The winding can be created with any number of poles depending on the speed of the motor needed. Higher poles indicate lesser speed whereas lesser poles indicate better speed....
