Equivalent Circuit Of An Induction Motor Rotor Stator

Equivalent circuit of induction motor stator circuit model.

Equivalent circuit of induction. Complete equivalent circuit referred to the stator. The rotor and stator inductance is larger in induction motor. Induction motor equivalent circuit.

The basic equivalent circuit of induction motor is shown in fig. The equivalent circuit is further simplified by shifting the shunt impedance branches r 0 and x 0 to the input terminals as shown in the circuit diagram below. Hence we can draw the induction motor equivalent circuit with the help of equivalent circuit of the transformer.

Rotational losses are 1300w. In the above circuit the only component that depends on the slip is the resistance. Approximate equivalent circuit of an induction motor.

Induction machine equivalent circuit model we have seen that induction machines as you might guess from the name operate on the principle of induced currents. Per phase equivalent circuit a 480v 60 hz 6 pole three phase delta connected induction motor has the following parameters. As explain in working of three phase induction motor.

One way to analyse and understand the operation. There are still two magnetic fields one from each of the rotor and stator but the rotor field is induced by the stator field. The steinmetz equivalent circuit is expressed simply in terms of the following components.

Which is very similar to that of a transformer. A more generalized induction motor equivalent circuit may be obtained by omitting the prime notation on r 2 and x 2. Approximate equivalent circuit the magnetic circuit of induction motor has an air gap so exciting current is larger compared to transformer so exact equivalent circuit should be used.

This is shown below. The motor drives a mechanical load at a speed of 1170 rpm. R 2 s r 2 r 2 1 ss this equivalent circuit is shown below.

Three phase supply is given to the stator winding. It an induction motor when a 3f supply is applied to the stator windings a voltage is induced in the rotor windings of the machine. In induction motor we use distributed windings.

Another equivalent circuit may also be obtained by splitting r 2 s as. The approximate circuit is based on the assumption that v 1 e 1 e 2. Calculation of motor performance.

The induction motor is equivalent to a rotating transformer. The simplified equivalent circuit allows us to. In general the higher the relative motion of the rotor and the stator magnetic fields the higher is the resulting rotor voltage.

Induction motor equivalent circuit induction motor concepts. From the preceding we can utilise the equivalent circuit.
