The construction of Stator for any induction motor is almost the same . But the rotor construction differs with respect to the type which is specified above . Stator: phase winding The stator is the outer most . The relative motion between this field and the rotor induces electric current in the conductive bars. In turn these currents lengthwise in the conductors react with the magnetic field of the motor to produce force .
The rotor is connected to the mechanical load through the shaft.
Depending upon the type of rotor construction used the three .
A typical squirrel-cage induction motor is shown. Operating theory of squirrel cage induction motor. Phase Wound induction motor (slip-ring induction motor ). Squirrel cage induction motor and 2. Both types have similar constructed rotor, but they differ in construction of rotor.
An induction motor can therefore be made without electrical connections to the rotor.
Three - phase squirrel-cage induction motors are widely used as industrial drives because they are rugge reliable and economical. Single-phase induction motors . Whereas in Wound rotor induction motor (WRIM), - phase windings are present on the rotor. Department of Electrical Engineering.
This paper presents the design of three - phase induction motor (IM) for high speed with torque speed curve suitable for vehicle propulsion applications.
W, for both, for its elements an for motor and the electric motor as an assembly. For this reason, efficiency of these machines is important. Along with this, the squirrel cage induction machine is preferred because of its ease of manufacture, low cost . Various faults are occurring in the stator as well as in the rotor of - phase squirrel cage induction motor such as bearing fault, broken rotor bar fault, etc.
This paper presents an analysis of fault occurring in the bearing of - phase squirrel cage induction motor by using artificial intelligence method.
They are cheaper, more rugged and easier to maintain compared to other alternatives. Induction motors are the most commonly used electrical machines.
