Answer Posted / thowsif_emerson_csm team
The windings on the rotor of a squirrel cage motor is
comprised of aluminum (or sometimes copper) bars embedded
in the steel laminations of the rotor. The ends of the
rotor bars are shorted together by rings at each end of the
rotor. There is no external electrical connection to the
rotor. The bar and ring structure looks like an exercise
wheel for a pet squirrel.
The rotor of a slip-ring motor is wound with wire coils.
The ends of the windings are connected to slip rings so
that resistors or other circuitry can be inserted in series
with the rotor coils through carbon brushes that slide on
the slip-rings allowing an electrical connection with the
rotating coils.
