The rotor core mounts on a steel shaft to form a rotor assembly. The wound rotor is another type of induction-motor-rotor construction. A major difference between the wound rotor motor and the squirrel-cage rotor is that the conductors of the wound rotor consist of wound coils instead of bars.

(AP) -- New York regulators say the new telephone area code that will be added to eastern New York's 518 region will be 838. The Public Service Commission last week approved the overlay in the 17-county region to meet demand for new phone numbers. That means existing numbers will keep the 518 area code and new ones will begin with 838. Because there will be two area codes within the region, everybody will have to dial 10 digits for local calls. To call outside the region, they'll have to dial 11 digits -- 1 plus the area code and 7-digit number. The change will be phased in over a period of months. Day trips from Albany: 9 fun places
