squirrel cage induction motor with relatively low resistence
is used 4 fans,most machinary tools,centrifugal pumps,wood
working tool,cage induction motor relatively high resistence
is used 4 crusher,compressor,reciprocating pump, and cage
motor with high resistence is 4 punching presses, shears,
hoists n elevator.wound rotor im is used load requiring
severe starting condition or for load requiring speed
control they r also used 4 hoists,copresser n elevator

Answer / gaurav patidar

Induction motors are used in thermal power plants in
ID,FD,PA fans.Also in the boiler feed water pump and for
coal mills.

Answer / patel ronak r

INDUCTION MOTOR IS USED FOR HEAVY RESISTANCE MACHINERY.
LIKE CENTRIFUGAL PUMP,HIGH GEAR PUMP, CRUSHER
PULVERISER,AND SOME HEAVY ROTATING PARTS LIKES IN CHEMICAL
COMPANY MANY OF THE BIG RACTOR SO IT'S AGITATOR ROTATING
THIS TYPE OF INDUCTION MOTOR USED. BECAUSE IT'S EFFIENCY IS
VERY HIGH.AND IT'S LOSSES LOW.RESISTANCE OF INDUCTION MOTOR
IS VERY HIGH.

Answer / navneet phogat

Three phase induction motors are used wherever the application depends on AC power from the national grid. Because they don't need commutators they are particularly suitable for high power applications.
They are available with power handling capacities ranging from a few Watts to more than 10 MegaWatts.
They are mainly used for heavy industrial applications and for machine tools.
The availability of solid state inverters in recent years means that induction motors can now be run from a DC source. They are now finding use in automotive applications for electric and hybrid electric vehicles. Induction motors are seen as more rugged for these applications than permanent magnet motors which are vulnerable to possible degradation or demagnetization of the magnets due to over-temperature or accidental over-current at power levels over about 5 kW. Nevertheless, the induction motor can be ill-suited for some automotive applications because of the difficulties associated with extracting heat from the rotor, efficiency problems over wide speed and power ranges, and a more expensive manufacturing process due to distributed windings. Permanent magnet and reluctance motors may offer better solutions for these applications.
