Squirrel cage Rotor induction motor:
Â· The construction of this type of rotor is very simple and whenever there is anrequirement for lower torque then such type of rotor will be beneficial.
Â· This consist of a drum having number of circular holes which are in parallel with the shaft.
Â· We are going to place metals like Copper or aluminium bars in the holesand those bars are welded to the end rings to establish the electrical contact with them.
Â· We can see in diagram that end ring is shown with the faint dotted lines
Â· The reason behind the name Squirrel cage rotor is that the end rings and the Bars look like an cage it is named as an squirrel cage rotor.
Â· Rotor assembly will not be accessible to user due to short circuit of the bars.
Â· There is no any external connections to be added as that of sliprings type of rotor like external resistance.
Applications of Squirrel cage Motors:
1. Fans and blowers
3. Water pumps
4. Drilling machines
5. Lathe machines
6. Printing Machines.
