A dynamic machine model of an integral-cycle controlled single-phase induction motor is derived by properly choosing a stationary d-q reference frame. By utilizing the derived model it is revealed that two types of capacitor connection to the machine windings are equivalent, and that the integral-cycle controlled single-phase induction machine switches its operation between two distinct modes. ...

Induction motor is the most popular load in the industry, it is very important to study about the effects of voltage quality on induction motor performance. One of the most important voltage quality problems in power system is voltage unbalance. This paper evaluates and compares two methods including finite element method (FEM) and equivalent electrical circuit simulation for investigation ...

A single-phase to three-phase drive system composed of two parallel single-phase rectifiers, a three-phase inverter and an induction motor was proposed. The system combines two parallel rectifiers without the use of transformers. The system model and the control strategy, including the PWM technique, have been developed. The complete comparison between the proposed and standard configurations h...

This paper presents a non-linear dynamic model of a permanent capacitor single-phase induction motor. The D–Q axis model of the permanent capacitor induction motor, based on the state vector analysis of the system is conducted; revealing the periodic and chaotic phenomenon under different system parameters. Accordingly, a chaotic-speed fan can be achieved by appropriately varying the motors’ in...

Induction Motor especially the squirrel cage type of this motor plays important role in industry. According to the application type, this motor place against various stresses that are caused failure in the motor. The most common failure is related to the Stator winding. Among these failures are turn-to-turn, coil-to-coil and phase to phase faults. Flow the high current do to the induction resul...

This paper deals with the design and evaluation of a robust controller for static VAR compensator (SVC) in remote industrial power systems to enhance the voltage profile for three-phase single cage induction motor (SCIM) loads. The controller design is based on H∞ theory to deal with uncertainties arising in industrial network modelling. &#10The performance of the H∞ controller has been evaluat...

In this paper, the noise of electric motors is analyzed in order to obtain information for the detection of faults. Significant noise spectrum differences between healthy motor and motors with different faults are observed. The faults analyzed are bad bearing in the three phase induction motor and broken bars in single phase induction motor. The high-frequency spectral analysis of noise provide...

<span lang="EN-US">Single-phase induction (asynchronous) motors are widely used at home. These have two windings and usually operate a lower performance than 3-phase asynchronous which three windings. For this reason, study aims to design new winding of single-phase motor by increasing the number phases in order increase motor. This research was focused on 36 slot capacitor-start capacito...
