The stator construction of a three-phase induction machine is similar to that of a three-phase synchronous machine. A three-phase winding is placed in a number of slots in order to produce a rotating sinusoidal mmf wave.
UNIT 3. INDUCTION MOTORS OBJECTIVE The aim of this chapter is to gather knowledge about the following topics of Induction motors. 1. Construction, types and principle of operation of 3-phase induction motors. 2. Equivalent circuit of 3-phase induction motor. ... Actually the typical starting currents for an induction machine are ~ 5 to 8 times
Induction machine is a singly excited machine in the sense that stator of induction machine is fed from 3-phase supply and rotor gets its power from stator through induction, hence called as Induction machine.Constructional Features
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. An induction motor can be used for different applications with various speed and load requirements.
A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface. It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface.

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.
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from …
Synchronous motor and induction motor are the most widely used types of AC motor. Construction of a synchronous motor is similar to an alternator (AC generator).A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.
