a very robust squirrel cage guaranteeing a long life time of the motor without considerable maintenance efforts is produced at reasonable expenditures. In recent years a new technology has been developed allowing a die-cast filling of the rotor slots with copper. Since copper has a better electric conductivity …

Squirrel Cage Rotor Three Phase Induction Motor |… The rotor core is cylindrical and slotted on its periphery. The rotor consists of uninsulated copper or aluminium bars called rotor conductors.The entire structure looks like a cage, forming a closed electrical circuit. So the rotor is called squirrel cage rotor. Squirrel-cage rotor - Infogalactic: the planetary knowledge… A squirrel-cage rotor is the rotating part (rotor) used in the most common form of AC induction motor. It consists of a cylinder of steel with aluminum or copper conductors embedded in its surface. An electric motor with a squirrel-cage rotor is termed a squirrel-cage motor.

Know about the different winding slots, lamination of the stator and its construction. Also appreciate the rugged construction of squirrel cage rotor and know the spectacular reasons for the skewed arrangements of the rotor conductors.

Squirrel Cage Rotor Testing

Timeline of the electric motor - Howling Pixel Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates, the resistance can be decreased.Compared to a squirrel-cage rotor, the rotor of the slip ring motor has more winding turns; the induced voltage is then higher, and the current lower, than for a squirrel-cage
