If you really do mean the number of 'turns', then you cannot really determine this, as it is determined as a part of its design process and can vary considerably from machine to machine.
If, on the other hand, you actually mean 'windings' ('coils') then, typically, there are two: the 'main winding' and the 'auxiliary winding'. The purpose of the auxiliary winding is to supply a magnetic field that is out of phase with the main winding and which then results in a rotating magnetic field necessary to start the motor and turn in in the desired direction.

How do you start a motor?
Be it three phase or single phase, larger motors should be started with a magnetic contactor.
Can a single phase generator run a 3 phase air conditioner?
Depending on who does the work it could be less expensive than getting a different air conditioner. The compressor will also need a capacitor and some rewiring. The old unit could have a 3 phase blower motor also which could run the price up even more. Although the changes can be made, the warranty at best will probably be a one year warranty and a new unit could have a 5-10 year warranty.
If a three phase motor loses one leg will it turn backwards before it burns up?
If a three phase motor loses one leg it will do neither of what you suggest. To change the rotation of a three phase motor any two motor leads must be interchanged. When one leg of a three phase system goes down it is said to be single phasing. The overload protection on the motor senses the higher current on the other two legs and trips the overload heaters. This in turn drops the contactor open and disconnects the motor from the supply.
Can a 3.3 KW 230v 6 amp motor be connected to a 2.2 kVA single phase AC Generator?
230 v 6 amps is 1380 VA which equals about 1 kW, so a 3 kW motor implies it's a 3 phase motor. It would turn over on a single phase supply in whatever direction it was first spun in, but the performance would be poor and the motor or generator could get damaged.
What are the advantages and disadvantages of single phase and three phase in the electrical supply system?
In Australia most power is generated in 3 phase the split down to single phase wen it reaches individual residences 3 phase power is more efficient to produce. most single phase motors have switching gear and capacitors to help kick a motor on when it starts because single phase power doesn't have enough power to turn over a motor. 3 phase motors are generally simpler and require no starting gear ( normally cheaper to build) Most workshops have 3 phase machinery for the extra power it prvides Some motors can be 2 phase (rare) as well.
What is the functional operation of a single-phase capacitor start motor?
As with any motor the function is to turn electrical energy into mechanical energy.
Why do you connect a capacitor with an Ac motor?
The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.
How do you turn a 3 phase motor in to a generator?
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
How do you start a motor?

How is direction of rotation for single phase induction motor determined?
A single phase induction motor is not self starting; thus, it is necessary to provide a starting circuit and associated start windings to give the initial rotation in a single phase induction motor. The normal running windings within such a motor can cause the rotor to turn in either direction, so the starting circuit determines the operating direction.

Can you convert a three-phase motor to a single-phase motor?
Use only one of the legs (L1-L3), and the neutral. Some three phase circuits don't have a neutral. If that is the case, then you cannot run single phase.CommentYou don't need a neutral, providing the voltage is appropriate, you can get a single-phase supply by connecting the load between any two lines.

How do you prove that a rotating magnetic field is produced when a 3 phase supply fed to a 3 phase winding?
The motor will turn

Is it possible to make single motor car turn?
Every single car in the world only has one motor so yes it is possible.
