Electric Paramotor! - 11th June 2006

World`s First Electric Paramotor!
The first flight of an electric paramotor, earlier this month, could herald a new era in sport aviation. On Sunday I was lucky enough to meet the brains behind this revolutionary paramotor and see it in flight. This could be the future of powered paragliding?/b>





Csaba Lemak and Patrick MacKenzie of Toronto have been spending the past year perfecting their dream machine ?an electric paramotor. These two maverick visionaries believed that battery and motor technology could meet the challenge, despite expert opinions to the contrary. The challenges they faced were many; power density, heat dissipation, throttle control, weight reduction, reduction of charging times, speed controller issues. After considerable investment of time and money the pair had produced a working prototype, mounted on the lightweight, but sturdy Walkerjet frame. Testing and development continued throughout the winter months. A few burnt out motors later, the fledgling was ready to leave the workshop. The learning curve has been steep, but Lemak and MacKenzie are certain they have overcome the main obstacles and are, even now, designing the successor to their first prototype. On Tuesday 6th June Csaba Lemak took the first electrically powered paramotor into the air, making a small but not insignificant notch in aviation history. On Sunday 11th June the machine was ready to meet the world and I was glad to be invited along to witness the world`s only electric paramotor up close.

我有一朋友在帮我开发电动机,已做到2KW了,现在已找到提升功率的办法,下一个准备做11KW的(15马力)可以推动力伞了,而且可以做到2000-3000转/分,就是可以直驱
一米以上的桨了,有兴趣的同好可以定,价格吗比国外的就便宜多了.

电机不是问题，关键是电池有多重，能供电多久。就算电机没有重量，光是电池（当今比能量最高的锂聚合物电池）10千瓦小时重量也在50千克上下，而15马力内燃机一小时最多烧5千克油。

所以要用太阳能电池啊:em15:

按你的算法,10KWH,50KG,我用3C放电,20分钟.重量17KG左右,已经可以实用了!

当然。10C放电（现在的锂电能轻松达到）就更轻了。不过以分钟计的飞行时间除了运动休闲有多大实用意义？

其实一般飞动力伞的每次飞也就半小时而已,要是飞滑翔伞的,有20分钟足以把人推到足够的高度,找到上升气流,这样不要爬山就能享受滑翔的乐趣,在气流不稳是可随意开关动力.

17公斤的电池差不多要用1万7千，这价格能买一台不错的发动机。

没错，所以说[size=-2][size=-2][size=-2]除了运动休闲

我寻了价,锂聚,40.8AH(6.8X6),74V,9000元,17.4KG.加电机电调,4000元.
13000,哈哈,有点贵,但也不离谱

小布丁

哪儿有这样的锂聚? 多重?
很贵, 但也不离谱. 其它电池是否有可能? 比如镍氢.

How long can it fly?
Currently flight times on a single charge have been around 35 minutes, although it is expected that the batteries could run for longer. All flights are being conducted for testing purposes only, at the moment. Every flight allows valuable data to be collected.

能飞多久? 一组电池35分钟左右.

Is there any maintenance?
NO! The finished product will have a brushless direct drive. Just plug it in and fly...

无刷, 直驱!

How heavy is the motor?
1.5 kg
What power does it generate?
17HP

无刷电机重 1.5kg, 功率 17马力, 超过10kw啦.

How much does it weigh?
The prototype weighs 22kg. This will change, and we will be able to produce specialist lightweight training PPGs suitable for getting students in the air without having to bear the full weight of a machine.

它有多重? 原型机仅22kg, 也就是包含电机/电池(能续航35分钟)/电调.
