A new system has been designed at the US Department of Energy that achieves the objects of lower capital cost and greater customer service. This system, known as CyberTran/sup /spl reg//, utilizes improvements in computers, radio, and power semiconductors to achieve its objectives. The system, based on a distributed load concept in which a high number of smaller vehicles are utilized, is now being privately commercialized. The smaller vehicles can maintain the capacity of Light Rail Transit but with less infrastructure, both structural and electrical. On-demand operation and direct-to-destination travel become possible. Computerized vehicle dispatch and radio-ranging technologies maintain control over vehicle destinations and motion. The concept is presented and the electrical system described.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

Flux generating permanent magnets, magnetically-soft flux carrying components, and frequently a combination of the two, must routinely be processed and assembled to achieve a specific end result. Various material characteristics and interactions may prevent the magnetic flux from going where it is needed and/or reduce its amplitude to an inadequate level to achieve the required result. This paper describes some problems that are commonly encountered in the process of building magnetic devices and offers insights into how they can be dealt with in practice. Some examples of actual products are discussed.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

According to the characteristics in time domain, the interferences can be divided into periodic narrow-band noise, the white noise, the periodic stochastic noise and the stochastic pulse noise. Among these interferences, the stochastic pulse noise is the most difficult to be eliminated because of the strong comparability in both frequency domain and time domain between the PD pulse and the noise pulse. The paper introduces the characteristic of difference PD signals and noises both in time domain and in frequency domain, proposing a new algorithm to suppress the stochastic pulse interference. The algorithm is based on the pattern recognition by the neural network (NN). The data sampled from both the on-line PD monitoring and off-line PD experiment over winding bar have been used to train and test the algorithm. The results given in the paper shows that the new algorithm is effective in suppressing of the stochastic pulse interference and the algorithm is useful to suppress other noises.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

This new approach for maintenance, not only includes various on- and off-line diagnostic procedures, but also a \"library of experience\" represented by multiple design know-how, generator fleet experience, unit history, operational characteristics and OEM records. The capability for advanced diagnostic trending and assessment will be obtained by providing expert analysis of stator winding, rotor winding, and generator bearings through rapid remote communication with local stations and a remote server. The system comprises a so-called virtual working environment providing intelligent software agents to support human experts in diagnostic pattern visualization, analysis, trending and assessment.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

This method of heating, although not new, is gaining momentum in the motor industry as a fast and precise method of heating and curing parts. This paper is a case study of the design of an Induction Heat Varnish Trickle machine designed for DC motor armatures. The study will cover the aspects of the design of the system including power supplies and optimizing coil design. Comparisons will be made during the study with more conventional heating systems (convection and infrared) showing the differences in heat up rates and efficiencies along with the floor space differences. A final comparison will evaluate the power requirements for the three different designs. Once this analysis has been completed, a summary will be provided for analyzing new applications to determine whether Induction Heating is a viable method of curing for a particular process.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

In many companies, individual units are randomly tested for some finite number of hours or cycles. Corrective actions are haphazard, often ineffective. Worse yet, they may never be implemented; without statistical guidelines defining test limits, the results can be ignored. With less of a financial burden, a truncated test plan will improve the quality of information, leading to better corrective actions and fortifying warranty analysis and predictions.

Their inherent latitude in processing parameters, to impart optimum cured properties to a given coil winding configuration, accounts for both their continued popularity in engineering applications and for the tendency to overlook or misinterpret the requisite processing parameters at the task level which must be managed in order to achieve optimum cured properties. A closer look reveals how understanding compound chemistry enables task level management of material acceptance, handling and storage, impregnation processing and cure management to increase manufacturing yield, lower unit cost and ensure optimum life cycle performance.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

From a component design perspective, GD&T provides the engineer with a communication tool to fully describe the functionality of the item dimensionally. Further, GD&T gives the manufacturing engineer geometric information that will affect process and fixture design. The quality engineer derives functionality information that will impact dimensional verification or inspection. Unfortunately, several organizations have attempted to implement Geometric Dimensioning and Tolerancing without a fundamental understanding of how the design process is impacted. Improperly applied GD&T can very quickly make a good design bad.
