Rotor (electric) - Wikipedia

A squirrel-cage rotor has a laminated iron core with slots for placing skewed ... The bars are usually made of aluminium or copper, but sometimes made of brass. rotor slot permeance harmonics under distorted air-gap flux probably behave as the rotor slot harmonics do under distorted air gap flux waveforms. A cageless rotor is ... FLUX WAVEFORM FOR CAGE INDUCTION MOTOR. Shy-Shenq Liou ... Among the harmonics, the third-harmonic is usually the most dominant one ...... Torques in Squirrel-Cage Induction Motors", lEE. Proceedings ... Difference Between Slip Ring & Squirrel Cage Induction Motor with ...

Why are conductors skewed in an induction motor? - Quora Rotor conductors are skewed because of these two main reasons- 1. Primarily to prevent the cogging phenomenon. It is a phenomenon in which, if the rotor conductors are straight, there are chances of magnetic locking or strong coupling between rotor & stator. 2. To avoid crawling. Why are the slots on the rotor of an induction motor skewed? In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages. This is called the rotor Skew. Rotor of an Induction Motor skewed due to following reason… With the bar skewed,the amount...

The rotor is a cylindrical core made of steel lamination with slots to hold the wires for its 3-phase windings which are evenly spaced at 120 electrical degrees apart and connected in a 'Y' configuration. The rotor winding terminals are brought out and attached to the three slips rings with brushes, on the shaft of the rotor.
