Three-phase AC motors can be divided into three general types: squirrel-cage, wound-rotor and synchronous. Only the squirrel-cage rotor motors and the wound-rotor motors are induction motors. The rotor circuit in an induction motor does not have an external power supply. Voltage is induced in the rotor windings by the revolving electromagnetic

The rotor of the squirrel cage three phase induction motor is cylindrical and Advantages of Squirrel Cage Induction Ro- tor. Its construction 

Lets see the construction of a three phase stator. The three phase windings are placed on the slots of laminated core and these windings are electrically spaced 120 degrees apart. These windings are connected as either star or delta depending upon the requirement.

The rotor of the squirrel cage three phase induction motor is cylindrical The below diagram shows a squirrel cage induction rotor having 

The paper aims to investigate the use of the Finite Element Method for electrical and mechanical faults detection in three-phase squirrel cage, induction 

of three-phase squirrel-cage induction motors, such as the motor speed, torque, Interchanging the power connections to any two of the stator.

The rotor of a three-phase squirrel cage Induction motor consists of a set of non-insulated bars that are interconnected by short-circuit rings.

This operating manual has been created for three-phase squirrel-cage single and dual speed induction motors, with shaft height above the mounting feet's surface of: 80, 90, 100, 112, 132, 160, 180 and 200 mm, designed to drive various types of machines and appliances.

We consider a three-phase squirrel cage induction motor. Each rotor bar is represented as an independent circuit connected to an end ring that has a 

Direct on line starters are commonly used to start small motors, especially 3 phase squirrel cage induction motors. As we know, the equation for armature current in the motor. The value of back emf (E) depends upon speed (N), i.e. E is directly proportional to N. At starting, the value of E is zero. So starting current is very high.

The rotating magnetic field. • The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating. The

three phase induction motor and performance targets the basic considerations for an induction motor design includes magnetic loading, the peak of fundamental component of radial flux density in the air-gap of the motor, core length, air-gap length, number of poles, number of stator and rotor slots, stator tooth width and slot depth, thermal

The construction of squirrel cage induction simple and rugged. Construction of slip ring induction motors needs slip rings, brushes, short-circuiting device, etc. This type of motor has less overhang and better space factor in slots. These motors have the highest overhang and poor space factor in slots. Cost and maintenance are less.

The rotor consists of a rotor core, a rotor winding and a rotating shaft. The rotor core is also part of the main magnetic circuit, generally by the thickness 

OPERATING MANUAL – THREE- PHASE SQUIRREL- CAGE INDUCTION MOTORS 3/32 PUBLICATION DATE: 9.05. - EDITION 4 An example of a standard motor marking: SKg 100L - 4A S – three-phase squirrel-cage induction motor, K – flange-type, g- „g” series, 100 – shaft height of 100 mm, L – frame size marking,

The series 1LA8 motors are totally enclosed fan-cooled three-phase squirrel cage motors with an internal air-cooling circuit for cooling. Located at the non-drive end of the stator housing is an air intake cowl that guides the external air. The external air is drawn in through an opening in the air intake cowl and flows axially across the outer

The rotating field due to stator currents and the rotor currents react to produce force on the rotor conductors and the torque. Fig. 1: Three Phase Induction Motor To understand this more clearly, assume that the stator field is rotating in an anticlockwise direction and the rotor is stationary as illustrated in Fig. 2 (a).

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 the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.

Starting of 3-Phase Induction Motors The induction motor is fundamentally a transformer in which the stator is the primary and the rotor is short-circuited secondary. At starting, the voltage induced in the induction motor rotor is maximum (Q s = 1). Since the rotor impedance is low, the rotor current is excessively large.
