A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)

Which type of ac motors are used in air cooler?
generally induction motor of single phase is used in air cooler.
What types of motors are used in escalator?
slip ring induction moters is used due to its high starting torq
Chorded windings are used in induction motors because?
Its the simplest way to reduce the harmonic induction torque(i.e. by weakening the stator winding mmf harmonics)
What are the different types of induction motors?
DOL(Direct Online starting) Star Delta starting Auto transformer starting Above methods are for squirrel cage induction motor Rotor resistance starting is used for wound rotor or slip ring induction motor
Why is a 3 phase induction motor is used in electric trains?
AC induction motors are not always used in trains as traction engines, however they are a popular choice. AC induction motors are very simple and reliable and aside from bearing wear they have no parts that wear out. This is because the power used by the rotating parts is supplied by the magnetism like in a transformer and so there are no slipping brushes. Most train systems actually use a DC supply, then a device called an inverter is used to convert the DC to variable frequency to drive the AC motor and control its speed. When this is done the AC induction motor is a very reliable and flexible engine and even allows energy recovery when the train is breaking.
Which motor is used in ceiling fans?
Single phase induction motors are used in ceiling fans
Examples of three phase balanced load used in industries?
* 3 phase motors * resistance heaters
Do all single phase motors have a start and run winding?
No, commutator motors as used in vaccum cleaners for example do not use a starting winding. Single-phase induction motors need a starting winding without which they will start in either direction if given an initial twist.
Which type of ac motors are used in air cooler?
generally induction motor of single phase is used in air cooler.
What type of motor is used in table fan?
Small house fans run on single-phase induction motors.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
What type of motors are used for ceiling fan and table fan are they same?
They are the same and they use a singe-phase induction motor of 15-30 watts
What are two types of motors used for hermetic compressors?
Rotary and Induction
Where theSlip ring induction motors are used?
The slip ring induction motors are usually used in the application requiring the low starting current or the high starting torque.
What are the advantages of open end winding induction motor over conventional induction motor?
Open ended induction motor - i assume you are talking about split phase induction motor. With these motors old style speed controlling method using external resistors can be used. However this is now obsolete.
Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
What are two types motors used for hermetic compressors?
Rotary and Induction
