| 3. | Their major advantages over conventional bearings results from the fact that there is no mechanical contact between rotor and stator 与传统轴承相比,其主要优点源于定子和转子之间没有接触。 |
| 4. | This article introduces one technique swayings mechanical contact whell based on hall componets to measure straight line long displacement 为此提出了一种以摆动式机械接触滚轮为基本原理,基于霍尔元件进行信号检测的直线大位移测量方法。 |
| 5. | The magnetic bearing is a novel type , high performance bearing , which suspend the rotor by magnetic force without any mechanical contact between rotor and stator 磁悬浮轴承是一种利用磁场力将转子悬浮于空中,使转子与定子之间实现无机械接触的一种新型高性能轴承。 |
| 6. | The switch is not only when switching over with production of electric arc , mechanical contact head easy to be damaged , but also it is slow to regulate , ca n ' t frequently operate , so limit the range of application of this kind of switch 这种开关不仅切换时伴有电弧的产生,机械触头容易损坏,而且调节速度慢,不能频繁操作,因此限制了这种开关的应用范围。 |
| 7. | The magnetic bearing ( mb ) , widely used in high speed rotation field , has the advantage over conventional mechanical bearing in many aspects , such as no mechanical contact between the rotor and the bearing , no lubrication , no pollution , long - life span and so forth 由于磁轴承的转子和轴承之间没有机械接触,无须润滑,无油污染,使用寿命长,这些特点使它在高速旋转领域获得了广泛的应用。 |
| 8. | This article briefly presented the principle of lower voltage power line carrier technology and spread spectrum technology , and discussed the advantage , the mode , the current state of spread spectrum technology applied to lower voltage power line carrier communication , and analyzed the channel transmission characters of lower voltage power line with mechanical contact 在本文中,简要阐述了低压电力线载波技术和扩频技术的原理,讨论了扩频技术在低压电力线载波通信中应用的优点、方式和现状,并通过大量实验,分析了带机械接触的低压电力线路的传输特性。 |
