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
- This winding, thicker and more wire is used than the starting winding.
- Therefore its resistance is low and induction is high.
- So it takes more current.
- 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
- This winding entails the task of pushing the rotor to start.
- The resistance of this winding is high and inductance is low. Thin and less wire is used in it.
- Therefore the induction of this coil is less, the magnetic field is more.
- This is why the motor feels the starting push much louder.
- That is why it is called starting winding.
Number of coils in single phase motor.
Single phase induction motor winding formula
- The stator is half the total number of slots.
- If the stator has 36 slots, the number of coals will be 18.
- 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
- After taking the number of slots for the starting coils, the remaining slots are for the running winding.
- Like 12 slots in 36 slots are for the starting coals, then the remaining 24 slots have a running winding
- Will go However, it is important to state that two-thirds (2/3) of the total slots are for running windings.
Running coils in the stator .
Electric motor winding formula
- It has also been reported that the number of coils in the stator is half of the total number of slots.
- Since the stator with 36 slots will have 24 slots for running winding, the number of running coils will be 12.
- In this way, 6 coils are of standing and 12 coils are running windings, the total number of coils in the stator becomes 18.
