The construction of an induction motor is very simple and robust. It has mainly two parts; 1. Stator 2. Rotor
Three phase motors are classified mainly in two categories based on the rotor winding (Armature coil winding) i.e. squirrel cage and slip ring (wound rotor motor). 1. Squirrel Cage Induction Motor 2. Slip-ring or Wound Rotor Induction Motor Related Post: Brushless DC Motor (BLDC) – Construction, Working Principle & Applications
The stator winding is overlapped at 120˚ (electrically) to each other. When a three-phase supply is given to the stator winding, the rotating magnetic field (RMF) induced in the stator circuit. The speed of the rotating magnetic field is known as synchronous speed (NS). According to Faraday’s law, EMF induced in the conductor due to the rate of cha...

Mar 8, 2024 · Learn about the basic principle, construction and types of three-phase induction motors, a common AC motor that converts electrical energy into mechanical power. Find out how Faraday's law, rotating magnetic field and slip affect the motor performance and applications.
The three phase induction motors are the most widely used electric motors in the industry. They work on the principle of electromagnetic induction. Due to the similarity in the working principle of the transformer, it is also known as the rotating transformer. They run at essentially constant speed from no load to full load.
Feb 24, 2012 · The three phase induction motor is the most widely used electrical motor. Almost 80% of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction, low cost, good operating characteristics, the absence of commutator and good speed regulation.
Nov 7, 2023 · Learn how a 3-phase induction motor works based on electromagnetic induction. The stator winding creates a rotating magnetic field that induces current and torque in the rotor winding.
Jun 20, 2024 · Three Phase Induction Motor Definition: A three-phase induction motor is an asynchronous motor that operates at a speed different from the synchronous speed, using three-phase power. Stator: The stator is the stationary part of the motor that receives the three-phase supply to generate a rotating magnetic field.
