Setilement of motor accidents claims with special reference to Kerala

The accident toll on our road traffic is staggering. Obviously this appalling toll of life and.health represents heavy economic loss in addition to human tragedy. the enormous increase in the number of motor vehicles with its rash, negligent and reckless use by unscrupulous, inexperienced and dangerous drivers in the most miserably managed roads coupled with concomitant hazards would draw our attention that Accident Prevention, and Accident compensation are thoroughly two compatiable aims. Proposed solutions to the traffic Problems abound. Preventive efforts concentrated on each of the variables the driver, the road and the vehicle are all being initiated. Still it is a Will the .Motor Vehicles are not considered as dangerous machines. Motoring activity is found useful.A competent and specially trained police force has to be created to deal with the traffic offences in a more scientific ways.The term ‘legal representative needs to be defined on the constructive aspects of relation and dependence.Services of legal aid and public counsels shall necessarily be extended to the poor Motor Accident victims.Timely reporting and timely investigation of Motor Accidents cases will reduce the number of fraudulent claims. There are instances where cases are taken in to investigation after several months of occurrence.It is hoped that the suggestions made above as a result of the present study, if pwgninto practice, may make a humble contribution to the prevention sssof motor accidents and to a faster and speedier settlement of motor accident compensation claims.

A Novel Slotless Halbach-Array Permanent-Magnet Brushless DC Motor for Spacecraft Applications

This paper presents the design and analysis of a novel machine family—the enclosed-rotor Halbach-array permanentmagnet brushless dcmotors for spacecraft applications. The initial design, selection of major parameters, and air-gap magnetic flux density are estimated using the analytical model of the machine. The proportion of the Halbach array in the machine is optimized using finite element analysis to obtain a near-trapezoidal flux pattern. The machine is found to provide uniform air-gap flux density along the radius, thus avoiding circulating currents in stator conductors and thereby reducing torque ripple. Furthermore, the design is validated with experimental results on a fabricated machine and is found to suit the design requirements of critical spacecraft applications

Design and Analysis of Zero Cogging Brushless DC Motor for Spacecraft Applications

This paper presents the optimal design of a sur- face mounted permanent magnet Brushless DC mo- tor (PMBLDC) meant for spacecraft applications. The spacecraft applications requires the choice of a torques motor with high torque density, minimum cogging torque, better positional stability and high torque to inertia ratio. Performance of two types of machine con¯gurations viz Slotted PMBLDC and Slotless PMBLDC with halbach array are compared with the help of analytical and FE methods. It is found that unlike a Slotted PMBLDC motor, the Slotless type with halbach array develops zero cogging torque without reduction in the developed torque. Moreover, the machine being coreless provides high torque to inertia ratio and zero magnetic stiction

Design and Finite Element Analysis of Hybrid Stepper Motor for Spacecraft Applications

This paper presents the design and analysis of a 400-step hybrid stepper motor for spacecraft applications. The design of the hybrid stepper motor for achieving a specific performance requires the choice of appropriate tooth geometry. In this paper, a detailed account of the results of two-dimensional finite-element (FE) analysis conducted with different tooth shapes such as square and trapezoidal, is presented. The use of % more corresponding increase in detent torque and distorted static torque profile. For the requirements of maximum torque density, less-detent torque, and better positional accuracy and smooth static torque profile, different pitch slotting with equal tooth width has to be provided. From the various FE models subjected to analysis trapezoidal teeth configuration with unequal tooth pitch on the stator and rotor is found to be the best configuration and is selected for fabrication. The designed motor is fabricated and the experimental results is compared with the FE results
