Two windings are used in a single phase motor coil winding.

   👉 Running coil winding 

  👉 Stating coil winding

 Running coil winding 

Single phase motor winding formula

1.  This winding, thicker and more wire is used than the starting winding.
2.   Therefore its resistance is low and induction is high. 
3.  So it takes more current. 
4.  Due to the running coil, the current load of the entire motor remains on the running winding.  

  Starting coil  Winding 

Single phase electric motor winding formula

1.  This winding entails the task of pushing the rotor to start.  
2. The resistance of this winding is high and inductance is low.  Thin and less wire is used in it. 
3.  Therefore the induction of this coil is less, the magnetic field is more.  
4. This is why the motor feels the starting push much louder. 
5.  That is why it is called starting winding.

Number of coils in single phase motor. 

Single phase induction motor winding formula

1.  The stator is half the total number of slots.  
2. If the stator has 36 slots, the number of coals will be 18.
3.   And if the number of slots is 24 then the number of coils will be 12.  

 Number of slots for running coils in the stator.

Motor winding formula

1.   After taking the number of slots for the starting coils, the remaining slots are for the running winding. 
2.  Like 12 slots in 36 slots are for the starting coals, then the remaining 24 slots have a running winding
3. Will go  However, it is important to state that two-thirds (2/3) of the total slots are for running windings.

Electric motor winding formula

1. It has also been reported that the number of coils in the stator is half of the total number of slots.  
2. Since the stator with 36 slots will have 24 slots for running winding, the number of running coils will be 12. 
3.  In this way, 6 coils are of standing and 12 coils are running windings, the total number of coils in the stator becomes 18.
