谈下天蝎星的电机~改了下翻译

BlueArrow

昨天淘宝上定了天蝎星Scorpion HK2-2221-8准备给450升级，店主发了个老外对于-6和-8两款电机的评价以及搭配不同齿轮的效果，粘过来大家分享下，我的英语很烂，自己看懂和讲出来让大家懂还真是两码事，见谅见谅，翻译得不是太好，大家将就看下。
-8+可能是这些电机里面最好的选择。

HK-2221-6, Kv = 4400, 最大功率 = 525W, 最大电流= 50 Amps
HK-2221-8, Kv = 3595, 最大功率= 475W, 最大电流 = 45 Amps
工作在3s锂电模式下的飞行感受：
HK-2221-8 用11T齿轮：主桨转速大约在2800 RPM：适用于入门飞行、悬停和基础动作。
HK-2221-8 用12T齿轮：主桨转速大约在3050 RPM：适用于进阶动作和中等程度的3D飞行。
HK-2221-8 用13T齿轮：主桨转速大约在3300 RPM：适用几乎任何3D动作，都能给出足够的动力，同时可以使用低要求的20C 2200mah的电池，而且电流也不是很大。

-6是为那些想要他们450榨到极限表现得人们开发的。使用这个电机至少得是25C 2200mah的电池和55A的电调，而且必须是碳纤桨。千万不要尝试用木桨！选用60A的电调是不错，不过有人测试结果表明瞬间电流可以达到70A，所以多多益善。
HK-2221-6用10T齿轮：主桨转速大约是3150RPM：可以作为适应这个电机的起步阶段，基本上可以胜任所有动作，除了一些极限的3D动作。
HK-2221-6用11T齿轮：主桨转速大约是3400RPM：对于大多数飞机，对于任何类型的3D飞行而言都可以胜任，同时还能让你在可操控的范围内。
如果你要尝试把12T齿轮装在这款电机上面，那么主桨转速大约可以达到3700RPM。这达到近乎疯狂的境界，但是有些飞手还是会尝试一下。恐怕市场上只有为数不多的飞机能够承受得住了。


原文是这样子的，我挑了些翻译的：
The following is straight from innov8tivedesigns.com

The full article can be found here.

I copied and pasted the information on the 2221-x motors for convenience. The -8 is probably the best overall choice.

HK-2221-6, Kv = 4400, Pmax = 525W, Imax = 50 Amps
HK-2221-8, Kv = 3595, Pmax = 475W, Imax = 45 Amps
HK-2221-10, Kv = 3000, Pmax = 440W, Imax = 42 Amps
HK-2221-12, Kv = 2500, Pmax = 400W, Imax = 38 Amps

These motors are by far the most popular ones in the 22mm series. They are designed to provide the maximum performance in 400 to 480 size electric helicopters. Because these motors are so popular, we will spend a little more time here giving specific application notes on each one. In addition to use in Helicopters, the HK-2221 series are also used very successfully in Airplane applications such as Pylon Racers and Hot-Liners that require a high power, high RPM motor. More recently, they have also become very popular for powering 65 to 75mm ducted fan units that are capable of utilizing a motor that is 28mm in diameter. For the purpose of this article, we will stick to Helicopter applications.

For operation on 3 Li-Po cells, there are 3 different motors that can be used, the HK-2221-6, -8 and -10 models. The most versatile model is the HK-2221-8 motor. This motor can utilize a wide range of pinion gears, and this allows the motor to "Grow" with the pilot as their flight skills improve from beginner up through moderate 3D type flying. Here are some common applications of the HK-2221-8 motor. These numbers assume a main gear with 150 teeth, which is very common for the 450 size machines.

HK-2221-8 with an 11 tooth pinion, providing a head speed of around 2800 RPM: This is good for entry level flying, hover practice and basic aerobatics

HK-2221-8 with a 12 tooth pinion, providing a head speed of around 3050 RPM: This is good for advanced Sport flying and beginning to intermediate 3D Flight.

HK-2221-8 with a 13 tooth pinion, providing a head speed of around 3300 RPM: This gives enough power for just about any 3D maneuvers, but still allows the use of a 20C 2200mah battery back, without pulling too much current.

The next most popular motor is the HK-2221-6 motor. This is THE motor for people that want maximum performance from their 450 class helicopter. Use of this motor requires a minimum of a 25C 2200mah battery and a 55 amp ESC, and carbon fiber blades are a MUST. Don’t even try running wood blades with this motor! The Scorpion 60 amp Heli Edition ESC is also a very good choice for this motor for pilots that want an ESC that has a 6.0 volt BEC circuit for more speed and torque from their servos. Here are a couple common set-ups for this motor:

HK-2221-6 with a 10 tooth pinion, providing a head speed of around 3150 RPM: This is a good place to start with this motor. You have all the power needed for just about anything except for the most extreme 3D type flying.

HK-2221-6 with an 11 tooth pinion, providing a head speed of around 3400 RPM: This will get you all the power that most helicopters can handle, and will allow for any type of 3D flying out there.

If you do try to go to a 12 tooth pinion with this motor, you will get a head speed approaching 3700 RPM. This is bordering on insanity, but some pilots will try it. There are only a couple helicopters on the market that will stay together

别这样说，还是应该鼓励下楼主。一则共享精神可嘉，二则意译能让模友看明白即可，又不是XX:em15:

太暴力了不好吧

我看的完就1个字：草暴了！   :em01:

hotayn

其实是3字  :em17:   太激动没办法 暴力 :em14:

我就是怕飞机散架了所以没有买这一个:em17:

BlueArrow

不知道飞起来怎么样，我买的是-8的，准备上13T的齿看看效果怎么样。
感觉kv值来看才3595，和430X的3550KV相差无几，但功率到475w，430X的才300w。估计扭力大，不那么容易掉转，温度会低很多，不像430x，每趟下来还得凉上五到十分钟，每次飞得时间还没有等的时间多~~唯一的优点430X暴省电，用12T的齿轮normal几乎可以到十分钟，还是3.7v以上，3D的话5分钟完了还能飞两分钟normal，也就是3.6V。
等到了货再说吧，毕竟我节衣缩食考虑很久才入了这个电机。

用-8的话配什么电调比较好呢？
飞BEAM-4用

BlueArrow

最少得50A，因为它的最大持续电流是45A，最大瞬间电流估计得过50A了。
最好是55A或60A的电调

我用2221－8配12T飞YT450PRO，好盈60A电调，没有感觉到暴力，动力一般。可能与我的机子起飞重量太大有关（接近900克）。今天刚换了13T，明天试飞下。不知我的15C电池悬停能否顶住6分钟:em15:

JimmyZ

其实-6用来飞3SA123不就正合适么

BlueArrow

15C飞3D有点悬，最低20C，最好25C甚至30C，3D最多5分钟吧，再多可能就危险了；
15C飞悬停应该没有任何问题，毕竟悬停的电流不会超过20A的，我用430X电机12T悬停模式25C2200mah锂电可以飞到十分钟以上，不过一般飞也就设个8分钟了。
对呀，高kv值的用A123应该很爽的，有兴趣的模友可以试下。

大连小鸟飞翔

个人意见：450搭配原则，重量超轻、时间耐久、动力足够。以前我也喜欢东改西改，后来发现亚拓的出厂配置是最合理的。

大连小鸟飞翔

450pro的出厂配置，主桨转数才1600转，飞机动力很好。转数上2600以上的飞机，总感觉怕怕的。

天蝎是好，美中不足是价格太贵，有买椟还珠的感觉:em15:
