This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...

In order to adapt to the requirements of the development for precision agriculture technology, making the rice seed tape planting technology has been widely used. The paper-making improved the design on the rice seed tape twisting machine especially the seed tape winding units. It proposed seed tape winding automatic control system based on STC90C514AD to realize the rotating speed adjustment o...

Permanent Magnet Machines (PMM) with a phase number (m) higher than three allow redundancy and lower torque ripple compared to their three phase counterparts. In this paper, a six phase permanent magnet machine with surface rotor magnets, designed with fractional slot tooth winding is proposed. A stator design with fractional slot tooth winding allows the design of a compact machine through sho...

Heat transfer is a critical aspect related to Electrical machine design. To insure a successful design of the electrical machine, special attention has to be given to thermal aspects in parallel with the traditional Electromagnetic design. For calculating the temperature rise in electrical systems such as electrical machines or power electronic systems it is important to measure the temperature...

This paper describes a computer model for calculating the surge propagation in the winding of electrical machines. The model considers the winding as a combination of a multiconductor transmission line and a network of lumped parameters. The frequency dependence of the winding electrical parameters are calculated and incorporated into the analysis by means of Foster and Cauer circuits. Finally,...

the paper presents a mathematical base modeling combined to modified-winding -function-approach (mwfa) for eccentricity fault detection of a round-rotor synchronous machine. for this aim, a 6-pole machine is considered, and the machine inductances are computed by mwfa in healthy and also under eccentricity fault. a numerical discrete-time method has been proposed to machine modeling in voltage-...

This paper considers the potential merits of using a HTS rotor winding in a low-speed high-torque synchronous generator and the possibility of building a small-scale demonstrator to investigate the practicality of building such a full-size machine. Pareto optimization results are presented for a full size machine with a high temperature superconducting rotor winding made from a new generation Y...

In this paper, a permanent magnet synchronous machine with fractional-slot and 5-phase winding is studied. By superposing of the back EMF (electro-motive force) phasors of all coil-sides in a phase winding, the winding factor of the machine is calculated. The idea of this calculation method is a clear, and operation is easy and fast. In normal working, one-phase open-circuit fault, opencircuit ...

The wind turbine converts the wind energy into electrical energy, wherein the electrical machines are coupled with wind turbines for this conversion. The electrical machines are liable to meet with faults, but to regain the system reliability the faults should be detected earlier. According to studies of electrical power research institute (EPRI) most of the faults in electrical motors are crea...
