A lot of old papers must have covered what you want to know. I have basic

centrifugal有什么关系。它不是在spool上的，而是在sideplate上的，所以casting的
时候，塑料片是不动的，那何来centrifugal force？Centrifugal brake比generic
magnetic brake有优势的地方，就在于它是在spool转得越快的时候，利用离心力，提
供越大的摩擦阻力，当spool转速下降的时候，离心力跟随下降，阻力也就下降了，这
样在理论上实现最大抛投距离，而且不会backlash。而generic magnetic brake提供的
阻力是不随着spool转速而变化的，提供的是线性的不变阻力，所以在casting开始的时

所以我真不觉得这几个塑料片是centrifugal brake，只能算是额外的固定阻尼。 |

发帖数: 7016 | 45 通过对比离心刹车centrifugal brake system和磁性刹车magnetic brake system，我觉得centrifugal break system从原理
上来说更合理一点。换句话说，如果其它条件都相同，用离心刹的轮比用磁性刹的轮投
得要远一些。
原因简单地说：在投掷的时候，离心刹产生的阻力是暂时的、即时的，而磁性刹的阻力
是持续的。
更近一步地解释：炸线一般出现在两个时间段，一是投掷起始段，二是落水时。落水炸
线很好解决，用大一点轴压力就行，熟练以后一般是不用轴压力而在lure落水时用大拇
指来停住spool。
投掷起始段的炸线是因为出线速度比lure飞行速度快（因为风阻力或其它的原因），这
种情况一般是在投出后的一小段时间（可能占整个投掷时间的五分之一），这段时间有
初始的加速度，如果lure稍有受阻，就会炸线。离心和磁性刹车系统就是为了减小这个
加速度。离心刹车是利用摩擦产生阻力：摩擦片由于离心力的作用向外伸出，摩擦到固
定的轮圈。磁性刹车是利用磁性产生阻力：通过调整磁铁片和spool的距离，磁铁片会
对spool的转速有限制作用。这两种刹车的不同之处在于 |

确实是workhorse reel里面的佼佼者。我有一个Exceler, 一个Tatula 100, 一个
Tatula CT，一个Tatula SV, 和一个Zillion。杆子方面有一个Tatula的杆子。这里就
比较一下吧，给感兴趣的钓友一些参考意见。
Exceler系列是属于低端系列了，比Aird系列要高一些，毕竟是金属框架，但又比中端
主力产品Tatula要低，基本上是downgraded version的Lexa 100。但跟Lexa 100系列一
样，现在基本停产了，市面上不多，这里提一下主要是因为个人觉得cast方面非常的好
用，虽然抛投距离不是最远的但也不错了，而且极少backlash，即使把brake调在
minimum的位置，几乎不用thumb。这点比较适合刚开始用BC reel的朋友。我觉得是因
为spool跟line guide的距离的原因，比一般的reel要远，所以线cast出去的时候，跟
line guide的摩擦阻力会小些。用的是Brake是普通的Magforc... 阅读全帖 |

时还行，但很快就发现问题多多。
1.像你说的，spool和frame之间的gap太大，这个gap本来应该是sideplate填上的，但
加工tolerance实在不怎样，所以这个gap在spool太满的时候绕线，而且很容易渗水进
去，我经常打开sideplate发现里面全是水。
2.它号称是centrifugal和magnetic dual braking，但我到现在也没搞明白它的
centrifugal brake的工作原理，实用中也很不稳定，噪音很大，加油也没用，所以我
基本就只用它的magnetic brake了
3.gear的加工精度实在不咋地，用了不到一两个月，就有那种明显的gear grinding的
感觉了，跟bearing没关系，想消除这种“geary feel”，只有更换pinion gear。所有
的reel用久了都不可避免的会出现这种“geary feel”，但质量好的象Shimano, Daiwa
的轮子，要很久以后才会变得明显。
