Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (SuperMotors and SuperGenerators) that can generically be categorized as SuperMachines. Compared to conventional machines of equivalent rating, these SuperMachines are expected to be less expensive, lighter, more compact, efficient, and provide significantly superior stable operation in a power system. The field windings are made with HTS conductor material (BSCCO, or Bi-2223) which operates at 35-40 K and can be cooled with inexpensive, ....etc

DIELECTRICS AND MAGNETIC MATERIALS



Insulators

Some materials like glass, ceramic, polymers and papers are non-conducting materials.

They prevent flow of current through them.

They provide electrical insulation.


DIELECTRICS

the non-conducting materials when placed in electric field modifies the electric field and themselves undergo appreciable change are called dielectrics.

By a row (eg 24) LEDs fast spin at the right time and the individual LEDs on and off can make an image formed. This command is an extension of a project last year, with a hand made clock was built by a row of LEDs. The intention is now to provide a communication between the sash and the environment, different patterns can be read. The PC must have written a simple program that can convert a bitmap to control signals to LEDs. An additional challenge is different intensities for the LEDs to provide, eg through a revolution the LEDs to burn and th ....etc

Double-Stator Switched Reluctance Machines (DSSRM): Fundamentals and Magnetic Force Analysis
Abstract
In this paper, a new switched reluctancemachine witha double-stator configuration (DSSRM) is introduced. The proposeddesign is based on optimization of themotional forces, whichleads to a high-grade electromechanical energy conversion process.A local examination of the force densities within and throughouta conventional switched reluctance machine (SRM) shows that themajority of the force produced is in the radial direction and doesno ....etc
