Axial-field electrical machines offer an alternative to the conventional machines. In the axial-field machine, the air gap flux is axial in direction and the active current carrying conductors are radially positioned. This paper presents the design characteristics, special features, manufacturing aspects and potential applications for axial-field electrical machines. The experimental from several prototypes, including d.c. machines, synchronous machines and single-phase machines are given. The special features of the axial-field machine, such a ....etc

Abstract

In this study, we propose some simple but effective throughput-approximation methods for finite-buffered closed-loop production systems with unreliable machines and exponentially distributed processing times. The proposed approximation methods are based on decomposition and aggregation principles. According to the method representing the decomposed systems, three different approximation methods are developed, along with a simple upper bounding method for throughputs. Extensive computational experiments are perform ....etc

Axial Force Sensor for a Semi-Autonomous Snake Robot



I. INTRODUCTION
Various developments in robotics concentrate on mobile
robots to aid humans in new ways in their work and life.
Typical examples are remote inspection and maintenance
devices, personal assistants, and rescue robots. This research
concentrates on a particular type of robot for inspection in
unstructured environments like rubble or rocks. This type,
snake like robots, was chosen becaus ....etc

Most of the gas turbines employ the axial flow turbines.

The article is concerned with axial flow turbines.

The radial turbine can handle low mass flows more efficiently than the axial flow machines.

Elementary Theory of Axial Flow Turbine:
The velocity triangles for one axial flow turbine stage and the nomenclature employed are shown. The gas enters the row of nozzle blades with a static pressure and temperature P1, T1, and a velocity C1, is expanded to P2, T2, with an increased velocity C2 at an angle Alpha2

Any machine that can forever without any extra energy given to it, is a perpetual motion machine obviously such machines requires energy to get than moving, but non thereafter. Every inventor, designer and scientist dreams of making such a machine which has the potential of solving most of the energy problems of this world. But the fact remains that it is impossible to develop such a machine. Because at some point of their working they violate either the first or the second law of thermodynamics. Still many hopeful inventors over a period of ti ....etc

Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (Super motors and Super generators) that can generically be categorized as Super machines. Compared to the conventional machines of equivalent rating, these Super machines are less expensive, lighter, more compact and efficient. The field windings are made with HTS conductor material which operates at 35-40 K and can be cooled with inexpensive cryocoolers. These advanced machines are attractive for use and at present they offer significa ....etc

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
