# Quick Answer: What is flux in induction motor?

Contents

In both induction and synchronous motors, the AC power supplied to the motor’s stator creates a magnetic field that rotates in synchronism with the AC oscillations. … The rotating magnetic flux induces currents in the windings of the rotor, in a manner similar to currents induced in a transformer’s secondary winding(s).

## How do you calculate the flux of an induction motor?

The d-axis component of the stator current isd is then directly proportional to the magnitude stator flux. By regulating and keeping constant isd, the decoupling of the torque control and the flux of the induction machine is achieved. Hence, if the stator flux is oriented along the d-axis, then φs = φsd and φsq = 0.

## How is motor flux calculated?

Flux cut by one conductor in one revolution = dΦ = PΦ …. (Weber), Number of revolutions per second (speed in RPS) = N/60. Therefore, time for one revolution = dt = 60/N (Seconds)

## What is flux with example?

Flux is a chemical purifying agent, flowing agent or cleaning agent. Most commonly, it is used in metal joining and metallurgy. Some examples of flux include: Ammonium chloride. Zinc chloride.

## What is current flux?

Electric flux means rate of flow of the electric field (electric lines of force) through a given area and electric flux is proportional to the electric field lines going through a surface. Current is rate of flow of electric charge through any given area.

## What is the formula for synchronous speed?

The synchronous speed of an AC motor is determined by the frequency of the source and the number of poles. The RPM is calculated by multiplying the frequency times 60 and dividing by the number of pairs of poles. This was explained in Chapter 6. Some motors are designed to operate at synchronous speed.

## When load on an induction motor is increased?

If the load on the induction motor is increased the current will increase to deliver the demanded power. The slip of the motor will increase with an increase of loading on the motor, and the speed of the motor will decrease accordingly.

## What is the working principle of induction motor?

Working Principle of Induction Motor

The motor which works on the principle of electromagnetic induction is known as the induction motor. The electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field.
