如果你曾经看过一个直接驱动(DD)hubmotor的内部,想法可能已经发生,你有在它的中间未使用的空间数量惊人,而且它也只是大小合适的安装控制器那里。

Look at all the empty space in the middle of these two DD hubmotors.

那么,你是不是认识到的第一人。所以,让我们看看谁在过去这样做,现在谁在做这个。

BionX, the “integrated controller” Original Gangster

两年前,我们写了一篇关于加拿大的BionX是如何落到困难的时候(to see that article, click here)。我是历史的粉丝,也是电气和机www.beplay2.com械的东西演变(to see our article on the history of ebikes, click here)。

www.beplay2.com历史充满了巧妙的发明,从来没有“成功”的,由于事情正在经营不善的业务方面的例子。有时,该产品是“它的提前”,或者它根本无法正常销售。下面是一些关于BionX公司和轮毂的设计细节。

Ebike controllers are most often designed to work with only one voltage. If you want to “hot rod” an ebike, garage builders often raise the volts and the amps. However, raising the amps is one method that is noteworthy because it also raises the amount of HEAT that the controller and motor suffer from.

伊夫斯杜贝,该公司将成为BionX的创始人。他设计的位于中央控制器后直接驱动humotor。

如果要避免过多的电机热,那叶​​伏加薪,因为控制器和电机可热损伤敏感。回来时,高电压电池组是不具备的,制造商不得不做出从无绳电动工具电池自身的高电压包(看到我们的建设在国内的电池组文章,请点击这里)。But even if you had the tools and skills to build a custom high-volt pack, the BionX controller has a very custom size and shape. So, it was quite an involved process to try and use an external controller to boost a BionX hub.

还有许多其他配置的线索表明,BionX侧重于做一个设计,是街道法律,并且也很难“黑客”(只是我的意见)。电动自行车的法律尚处于萌芽阶段,1998年,它被担心热rodders可能伤害行人,导致电动自行车的形象而被破坏,而不是接受。

较新的P系列BionX中心是在左边(设计麦格纳接手BionX后),和原来的旧的P系列是在右边。

通过具有hubmotor内部的控制器,一些布线杂波被淘汰,并且它是更难的所有者为“更动”与胆。不管细节,我不得不提BionX首先是因为他们是我能找到一个控制器位于该hubmotor内最早的参考。

所有-in-One的hubmotors?

我们写了一篇文章在一月份的2019对所谓的“全合一” hubmotors。As stated in the article, this is the most uncluttered type of drive system (with the motor, controller, and battery all in one housing), but…I don’t like them because the battery pack is forced to be small, and that also means that the battery pack is typically limited on how many volts and amps it can provide, not to mention it is also restricted to short range.

该Zehus hubmotor,与位于hubmotor内部的控制器和电池组(什么?)

话虽这么说,我要明确的是,其实我喜欢安装在轮毂内的控制器......对“一些”的设计理念。一个可怕的设计电动自行车并不意味着所有的电动自行车的都是垃圾。这同样适用于集成控制器作为工程学原理。

Tidalforce / Wavecrest motor

2004年Wavecrest宾馆电机(由Tidalforce电动自行车使用的)不再做,但值得注意的有以下几个原因。它有一个专有的7相正弦波控制器,这是“轻微”比普通三相控制器更有效。当然,我提到它,因为它的控制器被集成到他枢纽。

该Wavecrest宾馆电机,上Tidalforce使用电动自行车。

In the pic, you can see how the shank of the axle has a much bigger diameter than a common ebike axle, so the motor phase wires do not have to pass through a small-diameter hollow axle (which would limit them to being thin and weak). It also had optical sensors, which are impervious to heat, unlike the common and cheap Hall-sensors (看到我们在霍尔传感器的文章,请点击这里)。

他们是值得注意的最后一件事是,他们建立了电池组进入前hubmotor。它“看上去像”一2WD电动自行车,但后轮毂是电动机/控制器,以及前面hub was the battery pack

该铁磁流体问题

早在2017年四月,我们写了那篇关于包括增加铁液的少量直接驱动hubmotor成功的实验。然而,它并不能帮助中等驱动器或齿轮枢纽,由于施工的细节,你可以读了关于(to see our article of ferro fluid, click here)。

添加铁液几milliigrams来直接驱动hubmotor。

You don’t necessarily need to take a hubbie apart to add ferro fluid, but the pic above was provided to show readers what it would look like inside. The FF is the dark goo in-between the rotor magnets. FF is definitely a high-performance trick, and if you like large hubmotors because of their ability to absorb huge amps, then FF can really boost your performance for just a few dollars (to read our article on big hubmotors, click here)

There is normally a slim air-gap between the stator-coils (the electro-magnets that cycle on and off), and the magnets in the rotor. The side-plates of the hubmotor are typically aluminum, which ‘could’ absorb and shed heat well. However, the air-gap is a significant barrier to transferring the heat from the stator to the outside air.

只是FF的一个微小的量将填充定子和转子之间的空气隙。它是一种液体,所以它增加了非常小的阻力。既然是磁性的,你不需要它泄漏或沉淀成池担心。它粘在转子磁体,并创建一个流体桥的热可行进穿过。这意味着你的临时峰值安培(用于加速时几秒钟)可高达一倍,在某些情况下无任何伤害到电机。

由于FF提供了DD hubmotor性能惊人的增长,hubmotor的某些模式,以前一直“有点无聊”,现在可以考虑不俗的表现,一个可行的选择。下面列出的集线器都必须参照被视为他们的股票的能力,然后还加如果FF他们的潜力。

STROMER ST1

我不会把一个STROMER热棒,但...为合理平坦的土地(如海滩社区),使用限制为500W一个DD hubmotor并不可怕。中秋节驱动器经常需要经常转移到充分利用齿轮(这使得它能够很好爬)。然而,有些人喜欢的E-驱动与没有进行转换的简单(要看到我们的2013检讨STROMER ST1的,请点击这里)。

从左侧一个STROMER DD hubmotor的定子,和除去圆控制器(在右侧)。黑咕是“盆栽”防水电子,也从冲击和颠簸振奋了。

我看到的STROMER电动机的结构细节最初的反应是......加入FF将帮助了很多...如果...你可以砍控制器添加更多安培(你不能)。如果你在一个非常好的价格找到一个使用STROMER,要知道你能折腾股票“冰球”控制器,并添加解锁这个制作精良的产品的潜在外部控制器。

The Stromer is a Swiss-designed and German-made “Mercedes” type of ebike. The torque-sensor and control programming make this a low-powered exotic, like an expensive 4-cylinder car. It rides absolutely fantastic, but…there is no serious power available.

Like the Voilamart hub below, the Stromer controller is fully “potted” for waterproofing.要看到我们在你的防水电动自行车的文章,请点击这里

金电机“魔派”

如果你绝对必须有一个DD hubmotor,现在,你需要一个集成控制器,那么黄金汽车套件是“进入”系统。他们已经这样做了一段时间,因此他们不是在它新的,这是一个非常现实的产品。

The Magic Pie hubmotor family from Golden Motor.

这些hubmotors通告为具有可编程集成控制器,将与在24V,36V,和48V的电压的作用。如果你想转换一个BMX有一个孩子一台20英寸车轮,这可能是做的最简单的方法。他们的网站可以通过点击这里找到。

从黄金汽车“魔术派” hubmotor,它的集成控制器。

I don’t know of anyone who has added FF to a Magic Pie, but that would be awesome, and I will keep an eye out for any data on that.

Voilamart 1500W

我不知道我们公司的任何事情,并在2020年3月,他们是新的我。然而,这样的设计非常耐人寻味。如果您在DD集线器(而不是普通冲压钢盘)的中心采用铸铝蜘蛛枢纽将是更重,更昂贵,但是...铝将作为热海绵从任何吸收的热量你加速过程中遇到临时安培尖峰。然后,捕获的热量可随时间消散,当你刚刚巡航沿。

The cast aluminum spider at the center of the Voilamart 1500W hubmotor, with the controller removed. The spokes are flat to allow it to absorb heat from the controller…very clever.

I mentioned the cast-aluminum stator-core as a key feature found on the so-called “1500W” hubmotors (which have 35mm wide stators), and these are one of my favorite recommendations, since they have typically been able to run reliably on 2600W (52V X 50A). If you can add ferro fluid, you can even use many more amps for at least a few seconds, which is often all it takes to get to it’s top-speed.To read our article on a popular 1500W DD hubmotor, click here

该Voilamart控制器,从hubmotor的中心删除。未知清楚咕已经被怀疑是硅氧烷的防水的,并且一个样品具有通过“白酒”容易溶解粘质。ES成员“dastardlyman”事先知情同意程序的礼貌

该电机是标榜为48V系统,这意味着它可能有共同的63V最大电容。这“也许可以”使用14S 52V电池组,但尚未证实。如果您使用推荐的48V,那么1500W额定功率,导致31A的最大安培。不坏,但它肯定不会觉得像50A(这是相当不错的,如果你可以得到)。

I suspect that this motor would work quite well with ferro fluid, so the stator coils at an occasional 2600W (52V X 50A) would not be in any danger of damage from overheating. However, the stock controller does not seem to have a decent heat-shedding pathway. The wide and flat spokes of the stator spider (that the controller sits on) would absorb some heat, so that is good news.

如果我有一个,我想补充一个温度传感器,控制器,再看看她能承担多少。如果添加FF,那么我怀疑侧板可以吸收相当多的热量从定子蜘蛛,作为结果,控制器会显著增加从FF中获益。我还要补充一些热化合物控制器底座和定子蜘蛛接触点之间,以确保这是构建任何控制器热将具有体面逃逸途径。

The 34-MPH (55km/h) top-speed on flat land in a 26-inch diameter tire (450-RPM’s) suggests that the default model has a kV of 12.8/RPM’s per volt. (要看到我们在千伏和电机的设计细节文章,请点击这里)。上市意味着它有一个7速飞轮,而不是7速飞轮,但不要指望它。

好吧,这为三个DD hubmotors带有集成控制器,实际存在,以及两个从电动自行车的历史。www.beplay2.com这并不包括所有的多功能一体机,但...这是一篇文章,需要写,我只是做它的家伙...。
