项目摘要

1. For the purpose of developing a multi-stack disk type corona motor, sector-shaped rectangular electrodes which can generate corona discharges toward both sides of the electrode surface are proposed and investigated.These electrodes are consist of inner and outer parts in thickness of 8mm, and high voltage is applied to the inner electrodes throughout the inside of insulated holders which penetrate the outer electrodes. Each disk type rotor is composed of both-side printed circuit bord and the diameter of each is 180mm.(1)In order to develop such a disk type corona motor, it is needed to evaluate quantitatively the generated torque of the corona motor in various constant speed. Digital P-I velocity control system has been realized by using a DSP board to adjust a revolving speed of a dc motor which is used to measure the generated torque of the corona motor.(2)This improved torque measuring system was applied to the corona motor to investigate the effect of various motor parameters o … More n the generated torque. It is confirmed that even a single-stack disk type corona motor is capable of self-starting and multi-stack one can have a large generating torque m proportion to the number of surfaces of the disk type rotors. It is pointed out also that air gap length is very sensitive to the generated torque.2. As an application of a cylindrical corona motor with multi-blade electrodes, a corona motor fan type ozone air generator is experimentally studied. This corona motor fan forms appropriate air flow and ozone. Ozone is good for deodorization and sterilization of air. In this device, both ozone formation and fan rotating speed depend on the corona discharge current. So the ozone content in the air flow can be controlled by the applied voltage of the corona motor. It is confirmed that the ozone content is usually kept below the environmental tolerance limit.3. In order to extend the function of the ozone air generator, a corona motor fan type air cleaner was constructed and tested. In the usual static air cleaner, the air is circulated by an ionic wind formed by the corona discharges between positive and negative electrodes. However, the ionic wind is very weak, so the electric fan is necessary to circulate the room air and to improve the dust removal performance. Instead of the usual electric fan, the corona motor fan is applied. The performances of dust removal by using smoke of mosquito coils and the formation of ions and ozone are experimentally studied. And it is confirmed that this device can be applied to domestic and industrial uses. Less

1. 为了开发多叠盘式电晕电机，提出并研究了能够在电极表面两侧产生电晕放电的扇形矩形电极。这些电极由厚度为8mm，高压施加在贯穿外电极的绝缘支架内部。每个盘式转子由双面印刷电路板组成，每个印刷电路板的直径为8mm。 180mm。(1)为了开发这样的盘式电晕电机，需要定量评估电晕电机在各种恒速下产生的扭矩，通过使用DSP板来调节速度，实现了数字P-I速度控制系统。直流电机的转速，用于测量电晕电机产生的扭矩。(2)将这种改进的扭矩测量系统应用于电晕电机，研究各种电机参数对产生扭矩的影响。证实即使单叠盘式电晕电机也能够自启动，而多叠式电晕电机可以具有与盘式转子的表面数量成比例的大的产生扭矩。还指出，气隙长度非常大。 2．作为多叶片电极圆筒电晕电机的应用，对电晕电机风扇型臭氧空气发生器进行了实验研究，该电晕电机风扇形成适当的气流，有利于臭氧的产生。在该装置中，臭氧的形成和风扇转速都取决于电晕放电电流，因此可以通过电晕电机的施加电压来控制臭氧含量。含量通常保持在环境耐受极限以下。3．为了扩展臭氧空气发生器的功能，构建并测试了电晕电机风扇型空气净化器。在通常的静态空气净化器中，空气被离子排出。风形成的电晕在正负极之间放电，但离子风很弱，所以需要用电风扇来破坏室内空气，以提高除尘性能，而采用电晕电机风扇。对蚊香烟雾除尘性能以及离子和臭氧的形成进行了实验研究，证实该装置可应用于家庭和工业用途。
