Squirrel-cage rotor - Wikipedia 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. In operation, the non-rotating stator winding is connected to an alternating current power source...

INTRODUCTION: There has been, in recent years, an effort to make cast copper rotors for industrial use induction motors.

The cage rotor is often referred to as a squirrel-cage rotor, since it has a similar design to that of a squirrel-cage. The two main types of IM rotors are depicted in Fig 2.1 below. REMA / Gambica Repoet N0
