What are the advantages of skewed slots in the rotor of a ... What are the advantages of skewed slots in the rotor of a squirrel cage rotor? It helps to put on a little more traction. The rotor will stay on better because it is not as slippery. Squirrel-cage rotor - Wikipedia Squirrel-cage rotor. 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; the alternating current in the stator produces a rotating magnetic field.
