fault是什么意思
在线英汉翻译器首先说一下自己的理解，贝蒂尼的这个东西其实和亚当斯的原理差不多，高级的地方是他把驱动电路那里改成了自激电路，增加了能源的利用效率或者可以说是基本是把用的能源又给回收后继续驱动，这是比亚当斯还要牛的地方，结果就是驱动基本上不花费能源，而拾捡线圈却不停的拾取能量。

First, the switch 12 is clod. Becau the transistor 14 is off, no current flows through the winding 13a.
首先，开关 12 被关闭，因为三极管 14 是关闭的，没有电流流过线圈13a。
Next, the motor is started by rotating the rotor 20, say, in a clockwi direction. The rotor may be rotated by hand, or by a conventional motor-starting device or circuit (not shown).
下一步，发电机藉由旋转转子20被启动，在一个顺时针方向的方向。转子可能用手使其旋转，或藉着一个传统的开动电动机的装置或线路. （不显示）。
As the rotor 20 rotates, the pole 19 moves from the three o'clock position towards the pole piece 18b and generates a magnetic flux in the windings 13a,13b and13c. More specifically, the stator 18a and the pole piece 18b include a ferromagnetic material such as iron. Therefore, as the pole 19 moves nearer to the pole piece 18b, it magnetis the pole piece 18b to a polarity - South in this instance - that is opposite to the polarity of the pole 19 (which is North). This magnetisation of the pole piece 18b generates a magnetic flux in the windings 13a-13c. Furthermore, this magnetisation also caus a magnetic attraction between the pole 19 and the pole piece 18b. This attraction pulls the pole 19 toward the pole piece 18b, and thus reinforces the rotation of the rotor 20.

The magnetic flux in the windings 13a-13c generates voltages across their respective windings. More specifically, as the pole 19 rotates toward the pole piece 18b, the magnetisation of the stator 18a and the pole piece 18b, and thus the magnetic flux in the windings 13a-13c, increas. This increasing flux generates voltages across the windings 13a-13c such that the dotted (top) end of each winding is more positive than the opposite end. The voltages are proportional to the rate at which the magnetic flux is increasing, and so, they are proportional to the velocity of the pole 19.
expander在线圈中的磁束产生电压。这些电压与磁束正在增加的率成比例在，而且如此，他们与19 的速度成比例.
At some point, the voltage across the winding 13b becomes high enough to turn the transistor 14c on. This turn- on, i.e., trigger, voltage depends on the combined rial resistance of the potentiometer 15 and the resistor 16. The higher this combined resistan
ce, the higher the trigger voltage, and vice-versa. Therefore, one can t the level of the trigger voltage by adjusting the potentiometer 15.
在某一时刻， 13 b 电压足够高使三极管 14 c 的打开。触发电压由15和16决定，15和16的电阻越高，触发电压越高。因此，触发电压能藉由调整电位器 15 设定。
In addition, depending on the level of voltage across the capacitor 24, the voltage across the winding 13c may be high enough to cau an energy recovery current to flow through the winding 13c, the rectifier 23, and the capacitor 24. Thus, when the recovery current flows, the winding 13c is converting magnetic energy from the rotating pole 19 into electrical energy, which is stored in the capacitor 24.
此外，根据电容器 24 的两端电压,线圈 13 c 两端的电压要足够高以产生一个恢复电流通过整流器 23和电容器24.因此，当恢复电流发生，线圈 13 c 正在从使旋转极 19的磁能转化为电能储存到电容器24.
Once turned on, the transistor 14 generates an opposing magnetic flux in the windings 13obito
a-13c. More specifically, the transistor 14 draws a current from the battery 11, through the switch 12 and the winding 13b. This current increas and generates an increasing magnetic flux that oppos the flux generated by the rotating pole 19.

一旦三极管打开，在线圈13a-13c中产生反向的磁流。更具体而言，三极管从电池11中抽取一个电流，通过开关12和线圈13b。这个电流增长并产生一个增长的磁流且与转子产生的磁流相反。
When the opposing magnetic flux exceeds the flux generated by the rotating pole 19, the opposing flux reinforces the rotation of the rotor 20. Specifically, when the opposing flux (which is generated by the increasing current through winding 13a) exceeds the flux generated by the pole 19, the magnetisation of the pole piece 18 inverts to North pole. Therefore, the rever-magnetic pole piece 18 repels the pole 19, and thus imparts a rotating force to the rotor 20. The pole piece 18 rotates the rotor 20 with maximum efficiency if the pole-piece magnetisation inverts to North when the centre of the pole 19 is aligned with the centre of the pole piece. Typically, the potentiometer 15 is adjusted to s石家庄外教
et the trigger voltage of the transistor 14 at a level which attains or approximates to this maximum efficiency.
当反向磁流超过转子产生的磁流，反向磁流增强转子旋转。具体地，当13a的反向磁流超过转子产生的，磁芯18变成N极，所以，18排斥19，赋予转子20一个旋转力。当19中心与18中心对齐的时候18驱动20效率最高。通常，调节电位器15来设置触发电压以达到效率最高。
The transistor 14 then turns off before the opposing flux can work against the rotation of the rotor 20. Specifically, if the pole piece 18 remains magnetid to North pole, it will repel the next pole 19 in a direction (counterclockwi in this example) opposite to the rotational direction of the rotor 20. Therefore, the motor turns transistor 14 off, and thus demagnetisthe pole piece 18, before this undesirable repulsion occurs. More specifically, when the opposing flux exceeds the flux generated by the pole 19, the voltage across the winding 13b revers polarity such that the dotted end is less positive than the opposite end. The voltage across the winding 13b decreas as the opposing flu
x increas. At some point, the voltage at the ba of the transistor decreas to a level that turns transistor 14 off. This turn-off point depends on the combined resistance of potentiometer 15 and resistor 16 and the capacitance (not shown) at the transistor ba. Therefore, potentiometer 15 can be adjusted, or other conventional techniques can be ud to adjust the timing of this turn-off point.
