1.为了研制多堆盘式电晕电机，提出并研究了一种可向电极表面两侧产生电晕放电的扇形矩形电极，该电极由厚度为8 mm的内、外两部分组成，内电极上施加高电压，贯穿绝缘支架的整个内电极穿透外电极。每个盘式转子由两面印制电路板组成，直径为180 mm。(1)为了研制这种盘式电晕电机，需要对其在各种恒速下产生的扭矩进行定量评估。利用DSP板调节直流电机的转速实现了数字P-I速度控制系统，用于测量电晕电机产生的转矩。(2)将改进后的转矩测量系统应用于电晕电机，研究了不同电机参数对…的影响更多的是产生的扭矩。证实了即使是单叠式盘式电晕电机也具有自启动能力，多叠式电机也能产生与盘式转子面数成很大比例的发电扭矩m。文中还指出，气隙长度对产生的扭矩非常敏感。作为圆柱形多叶电极电晕电机的应用，对电晕电机风扇式臭氧空气发生器进行了实验研究。这种电晕电机风扇形成适当的气流和臭氧。臭氧对空气除臭和杀菌有好处。在该装置中，臭氧的形成和风扇的转速都取决于电晕放电电流。因此，气流中的臭氧含量可以通过电晕电机的施加电压来控制。经证实，臭氧含量通常保持在环境容忍度以下。为了扩展臭氧空气发生器的功能，研制了电晕电机风扇式空气净化器，并对其进行了试验。在通常的静态空气净化器中，空气通过正负电极之间的电晕放电形成的离子风进行循环。然而，离子风非常弱，因此需要使用电风扇来循环房间空气，以提高除尘性能。电晕电机风扇取代了通常的电风扇。实验研究了蚊香烟雾的除尘性能以及离子和臭氧的形成。经验证，该装置可应用于家庭和工业。较少

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
