# Is the resistance of starting winding is higher than running winding?

## Is the resistance of starting winding is higher than running winding?

We know that the start winding has the highest resistance and the run winding the lowest.

### What is the difference between starting winding and running winding?

Also starting winding have more number of turns and conductor size will be less and whereas running winding have less number of turns and size of conductor will be large compared to starting winding.

#### What is the relation between running winding and starting winding?

In single-phase, the auxiliary winding can be disconnected when the motor has gained speed as only pulsating magnetic field of a single-phase can run motor, that’s why it can be called a starting winding which is not required for continuously running the single-phase motor.

Why an auxiliary winding has high resistance value than main winding?

The auxiliary winding is wound with fewer turns and much smaller size of wire than that of the main winding, so that it has a considerably greater resistance-to-reactance ratio.

Which winding has the higher resistance?

start winding
The start winding has the highest resistance while the run winding has the lowest.

## Which motor has starting winding as well as running winding?

Single-phase induction motors are not self-starting without an auxiliary stator winding driven by an out of phase current of near 90°. Once started the auxiliary winding is optional. The auxiliary winding of a permanent split capacitor motor has a capacitor in series with it during starting and running.

### Which winding is the start winding?

A startup winding, also known as the auxiliary winding, is used to create the torque needed to start a single phase induction motor. This winding creates the rotating magnetic field in this type of motor by changing the relationship of the current in relation to the voltage.

#### How do you determine starting winding?

The way to determine which is which, is to measure the resistance of the winding. Use your multimeter and set it to the ohm scale. Now measure the resistance of each winding and write it down. The highest reading you obtained is the starting winding and the lower reading is the running winding.

Why do we use run and start windings in a single phase motor?

Adding aCapacitor in series with the start winding creates a larger phase shift and movement in the magnetic field which provides more starting Torque for applications where the motor must start under a load.

What is the purpose of the starting winding?

## Which winding will have a high resistance?

High voltage winding (primary winding in case of step down transformer) has higher resistance due to larger number of turns and thinner conductor.
