Single Phase Induction Motor Construction. The main parts of a single -phase induction motor are the Stator, Rotor, Windings. The stator is the fixed part of the motor to which A.C. is supplied. The stator contains two types of windings. One is the main winding and the other is the Auxiliary winding.
May 01, 2018· A converter fed 3 Phase Induction Motor Construction has the following advantages over a line fed motor:1.Smooth start up is guaranteed by variable frequency starting from a low 2.Soft starting and acceleration at constant current and torque are possible.
Construction of a 3 phase induction motor. Just like any other motor, a 3 phase induction motor also consists of a stator and a rotor. Basically there are two types of 3 phase IM - 1. Squirrel cage induction motor and 2. Phase Wound induction motor (slip-ring induction motor). Both types have similar constructed rotor, but they differ in ...
Construction of a single phase induction motor is similar to the construction of three phase induction motor having squirrel cage rotor, except that the stator is wound for single phase supply. Stator is also provided with a 'starting winding' which is used only for starting purpose.
2. WORKING PRINCIPLE OF THREE PHASE INDUCTION MOTOR . Working principle: Induction motor works on the principle of electromagnetic induction. When three phase supply is given to the stator winding, a rotating magnetic field of constant magnetic field is produced. The speed of rotating magnetic field is synchronous speed, N S r.p.m.
Chapter 8 Three Phase Induction Motor 8.1 Introduction The popularity of 3 phase induction motors on board ships is because of their simple, robust construction, and high reliability factor in the sea environment. A 3 phase induction motor can be used for different applications with various speed and load requirements.
Jan 15, 2014· Dragonfly Education is an education company, that is building proprietary education content for higher learning in technical streams. We are enabling B.Tech ...
A phase wound rotor of three phase induction motor is also called slip ring rotor and the motors employing this type of rotor are known as phase wound or slip ring induction motors.Slip ring rotor consists of a laminated cylindrical core having semi-closed slots at the outer periphery and carries a 3-phase insulated winding.
What is the operating principle of a 3ph induction motor? An electric motor converts electrical energy into a mechanical energy which is then supplied to different types of loads. A.c. motors operate on an a.c. supply, and they are classified into synchronous, single phase and 3 phase induction, and special purpose motors.
Construction of Induction Motor The three phase induction motor is a preferable type of motor. It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable. It is also called asynchronous motor because it does not run at a synchronous speed.

Jan 10, 2019· As an electrical drive, AC three-phase and single-phase motors use in various industries. Out of so many types of three-phase AC motors, the three-phase induction motor is very popular in industries. There are two main parts on a three-phase induction motor. Stator; Rotor; 1) Stator: It is a stationary part of the induction motor.
Those induction motors which employ squirrel cage rotor are called squirrel cage induction motors. Most of three phase induction motor use squirrel cage rotor as it has a remarkably simple and robust construction enabling it to operate in the most adverse circumstances. However, it suffers from the disadvantage of a low starting torque.
Split Phase Induction Motor The Split Phase Motor is also known as a Resistance Start Motor.It has a single cage rotor, and its stator has two windings known as main winding and starting winding. Both the windings are displaced 90 degrees in space.
