Webb14 juli 2024 · There are two types of rotors in induction motor rotors, Squirrel-cage rotor, and slip ring rotor. Squirrel cage rotor. A squirrel-cage rotor is a rotating element that is used in a three-phase induction motor. It consists of a steel laminated bar with a cylinder with aluminum or copper conductors embedded in its surface. WebbThe development of a wound-rotor induction motor from a single-phase transformer is depicted in Figure 1. In Figure 1(a), we see a section through one of several possible arrangements of a single-phase iron-cored transformer, with primary and secondary windings wound concentrically on the centre limb. infant lakers outfit
