Usually in commercial or industrial applications such as water pumps or large air handlers.
A small three horse motor can do a lot of work that a DC motor can...which DC used to be stronger than an AC motor would be. But the changing of voltages via a rectifier isn't always practical. But these days the three phase motors have the same torque and horsepower as a DC motor does.
BUT
Most of your three phase motors these days are controlled by a VFD or variable frequency drive which turns the three phases of AC into DC and then pulses it back to simulate an AC signal of various frequencies other than simply 60Hz and thus the motor can have almost any RPM.
The reason is that motors have a high inductance to them and power companies like to charge extra for a highly inductive power consumption. So when using a VFD all the power company will see is the diodes from the bridge rectifier.

Which type of motor is used in heat convector?
The fan in a convector is usually a single-phase induction motor.
What type of motor is used in centrifugal pump?
3 Phase induction motor because it produce high torque at starting
Which type of ac motors are used in air cooler?
generally induction motor of single phase is used in air cooler.
Why 2 phase induction motors are not used in industries?
A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors.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.)
Why pole changing method of speed control of three phase induction motor can not be used?
because its possible only where pole changing arrangements are given and pole changed motor draws more current then its actual pole which damages its windings.
Is three phase induction motor used for hoisting device?
ya three phase squirrel cage induction motor used to hoist travel application in industrial cranes
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 type of motor is used in ceiling fan?
single-phase induction motor is used in ceiling fan.
What motor is used in a fan?
Single phase Induction motor
What motor is used in grinders?
Single phase induction motor is used in grinder.
Are any capacitor in three phase induction motor?
There doesn't have to be but capacitors are sometimes used to correct the power factor.
What type of induction motor used in ceilinf fan?
Could be a single phase induction motor of 20-40 watts.
What type of motor used in agriculture water pump?
induction motor (3 phase)
What kind of motor is used either on ac or dc supplies?
single phase induction motor
Working principle of three phase drivers?
An electrical motor is such an electromechanical device which converts electrical energy into a mechanical energy. In case of three phase AC operation, most widely used motor is Three phase induction motor as this type of motor does not require any starting device or we can say they are self starting induction motor.For better understanding the principle of three phase induction motor, the basic constructional feature of this motor must be known to us. This Motor consists of two major parts: Stator: Stator of three phase induction motor is made up of numbers of slots to construct a 3 phase winding circuit which is connected to 3 phase AC source. The three phase winding are arranged in such a manner in the slots that they produce a rotating magnetic field after 3Ph. AC supply is given to them. Rotor: Rotor of three phase induction motor consists of cylindrical laminated core with parallel slots that can carry conductors. Conductors are heavy copper or aluminum bars which fits in each slots & they are short circuited by the end rings. The slots are not exactly made parallel to the axis of the shaft but are slotted a little skewed because this arrangement reduces magnetic humming noise & can avoid stalling of motor.
What motor is used for lathe spindle?
Single phase induction motor ( usually capacitor- start type)
Which type of motor is used in heat convector?
The fan in a convector is usually a single-phase induction motor.
