The steady-state equivalent curcuit for the general three-phase case consists of controlled generators too, this is due to general asymmetry. All the elements of the equivalent circuit can be directly calculated from the known phase-coordinate stator and rotor components. The equivalent circuit is simplified for a two-side asymmetrical two-phase machine, realization is carried out with d, q components. As an extreme case, approximative the steady-state equivalent circuit is also derived for a single-phase machine with rotor asymmetry. The analogy is pointed out with the well known steady-state equivalent circuit of the single phase motor with symmetrical rotor.
Single phase induction motor is anAC motorwere electrical energy is converted to mechanical energy to perform some physical task. This induction motor requires only one power phase for their proper operation. They are commonly used in low power applications, in domestic and industrial use. Simple construction, cheap cost, better reliability, eases to repair and better maintenance are some of its markable advantages.
The basic principle of operation is induction and hence the name Induction Motor. The main components of the Single Phaseinduction motor are stator and rotor.
Statoris known to be the stationary part. Usually, the single phase alternating supply is given to the stator winding.
Rotor is the rotating part of the motor. Rotor is connected to the help of a shaft.
Asquirrel cage rotoris used here. It has a laminated iron core with many slots.
Rotor slots are closed or semi-closed type. The rotor windings are symmetrical and at the same type it is short circuited. An air gap is there between the rotor and the stator.
The most practical applications of this motor are in application of single phase induction motor, clocks, drills, pumps, The stator winding in the 1induction motor has two parts: 1. Main Winding and 2.
