The main winding is the primary coil in an electric motor or transformer that generates magnetic fields and facilitates the conversion of electrical energy into mechanical energy (in motors) or vice versa (in Transformers). It is typically designed to handle the main electrical load, providing the necessary inductance and resistance for the device's operation. In motors, the main winding works in conjunction with other windings, such as the auxiliary winding, to ensure efficient performance and torque generation.

What is difference between main winding and auxiliary winding?
In the case of a capacitor-start/run single-phase induction motor, the main field is provided by the main (running) winding, and the capacitive branch is the auxiliary winding. In the case of a capacitor-start motor, the main winding is the running winding and the auxiliary winding is the starting winding.
If a split-phase motor has two poles on the main winding how many poles are needed for the auxiliary winding?
In a split-phase motor, the auxiliary winding typically has the same number of poles as the main winding to ensure proper phase shift and operation. Therefore, if the main winding has two poles, the auxiliary winding will also require two poles. This configuration helps create the necessary starting torque by generating a phase difference between the two windings.
Does a starting winding has more or less turns than a running winding?
Starting winding has more resistance and less induction than main winding, this means has smaller diameter and less turns.
Why are the compensating winding used in dc motor?
compensating winding is used for equal load sharing of two generators running in parallel. while interpole winding is used to minimise the effect of armature reaction by supporting the main field.
What is the number of turn in single phase motor?
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.
What is difference between main winding and auxiliary winding?
In the case of a capacitor-start/run single-phase induction motor, the main field is provided by the main (running) winding, and the capacitive branch is the auxiliary winding. In the case of a capacitor-start motor, the main winding is the running winding and the auxiliary winding is the starting winding.
Why must the auxiliary winding be different from the main winding in a split phase motor?
To differentiate it from the main winding and to make the path of the current different.

How capacitor is connected in a table fan?
The Capacitor with running winding is connected in parallel with main winding.
Lap winding and wave winding?
Both lap winding and wave winding are found in the use of DC generators. The main difference is as follows: lap winding is high current, low voltage, and wave winding is low current, high voltage.
If a split-phase motor has two poles on the main winding how many poles are needed for the auxiliary winding?
In a split-phase motor, the auxiliary winding typically has the same number of poles as the main winding to ensure proper phase shift and operation. Therefore, if the main winding has two poles, the auxiliary winding will also require two poles. This configuration helps create the necessary starting torque by generating a phase difference between the two windings.
Does a starting winding has more or less turns than a running winding?
Starting winding has more resistance and less induction than main winding, this means has smaller diameter and less turns.
What do you understand about the stator of an AC motor?
AC motor has two main winding components - stator and a rotor. Stator winding is stationary where as rotor winding is on rotating part.
Will a induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.

Why is a capacitor connected in series with starter winding?
In single phase motors, there are two windings. 1)Main winding 2) starter (auxiliary) winding. As per the double revolving theory in 1 phase machines, motor can rotate if current in the starter winding have near to 90 deg. phase shift wrt main winding. Now current flowing through capacitor leads by 90 deg. Ideally. So this is how we can get two currents which are having phase shift wrt each other. And the machine can rotate.
