该帖子解释了一个简单的太阳能人力车或人力车电路,该电路可以很容易地由家里的任何人建造,并与当地制造的车辆一起使用。阿米特先生要求这个想法。
该设计
选择BLDC
In one of my earlier posts I presented an idea which could be effectively used for制作电动踏板车使用BLDC电动机和相关电路。
在这篇文章中,我们讨论了一个类似的概念,但不只是为了简单起见而不使用BLDC电动机。
Although using an ordinary brushed motor could appear to be inefficient compared to its BLDC counterpart, a brushed motor nevertheless eliminates the need of complexBLDC driver circuitry涉及的与电动机的复杂接线使设计非常简单且外行友好。
此外,可以通过使用普通的IC 555 PWM电路来操作拉丝电机,这与BLDC电动机完全不同,BLDC电动机不仅需要在市场中找到很多复杂的控制IC,而且总是容易过时,并冒着担保的风险E-Rickshaw的时期可能已掺入该特定芯片。
PWM控制器
一个简单的使用IC 555的PWM电路可以通过控制其附着的控制电动机的速度来控制E-Rickshaw的速度。
这PWM concept makes sure that the energy consumption of the motor is significantly reduced and the efficiency is increased to the maximum possible range.
与两个1N4148二极管相关的100K锅会导致在IC的引脚#3处改变输出PWM,这又决定了TIP142晶体管的传导速率和连接电动机的速度。对于较高的电流,TIP142可以用等额的MOSFET代替。
晶体管底部的100UF电容器确保每当启动E-Rickshaw时,它都会提供慢柔软的电动机启动,而不是以混蛋或更高的初始扭矩。
这电位计should be of very high quality so that it is able to sustain the frequent speed control operations and may last for many many years without going through fatigue or mechanical wear and tear.
锅的典型规格应如下:
由Cermet或碳模制元素组成。
由BS和CECC批准
在Cermet中,在70摄氏度的2瓦处额定值2瓦
坚固的建筑
军事标准布局
用MC1/MH1标准密封的容器
坚硬的银板端子。
如何安装速度控制
速度控制锅旋钮可以很好地安装在驾驶员拇指附近的E人力车手柄中,因此控制人力车的速度可以最大程度地执行,并最低限度的努力。
电路的ON/OFF开关也应在安装在手柄上的驾驶员的拇指附近附近访问,以便驾驶员能够在关键或灾难性情况下立即关闭系统。
刹车
Th制动机制of the proposed electric rickshaw could be built using the conventional technique, however it must include a push-switch which may be in series with the supply voltage to the motor circuit, and must be configured in such a way that when brakes are applied the switch is first deactivated, switching OFF power to the IC 555 circuit and the motor.
这样可以确保在制动系统撞到车轮轴之前,首先禁用电动机,以防止其干扰制动过程。
太阳能电池板集成
为了将拟议的E人力车转换为节省太阳能人力车,可以将太阳能电池板与系统集成在一起,如下所述:
Although primarily the battery of the vehicle will need to be charged from an AC mains operated charger quite often, the solar panel will act like a secondary back up charger, and help reduce electric consumption of the vehicle which in turn will help to save power and money for the end user.
最好是可以安装在太阳能板roof of the vehicle and therefore could be as big as the size of the roof top of the E rickshaw, and rated at around 30V, 5 amps which looks quite economical for the proposed system.
使用上面指定的太阳能电池板,不需要额外的充电器控制器,因为面板的电压将自动使用24V电池规格自动自我调整,从而使设备更具成本效益。
这solar integration ensures that the vehicle battery is kept on a topped-up condition whenever the vehicle is idling and thus help to increase the efficiency of the vehicle substantially.
电池
对于包括驾驶员在内的合理的三个座位E人力车,24V 20安培电机将足够(假设值),并且整天最佳地操作该电动机,尽管用户可以更改用户,但24V 200AH电池可以很好地操作根据车辆运营时间表的需求和适用性规格。
moter RPM and v talk me
which type of cap for the 1uf 25v? i think the 10nf is ceramic cap and "what" wattage should the resistors be. i am currently operating a three wheel jazzy type 3 wheel scooter with a trailer i converted to a 12v starter motor to help with my yard work. i have been using a 12v 40 amp automotive relay. works fine but will do a wheelie now and then! yeah it's a little touchy!
电动机应优选刷,用于解释的555 PWM电路的DC类型
1uF/25V can be an electrolytic
reverse?
单独的开关需要DPDT继电器来启动电动机的反向移动
thanks for your timely answers and your time. i read this post a couple of times and it dawned on me after the "laymens" term employed was one of the reasons i enjoy your site(s) so much. I do realize this is a sight from the mid-eastern part of the world after reading the posts comments and some of the components which are deemed archaic here in the u.s.
但是,外行术语是我作为我教给商人的机器重建课程的讲师最喜欢的词之一。我是一名1A类机械师,只有其余的nack级别。计算机机械落在我的腿上,我在购买了第一台“广播棚屋可可”计算机的同时工作。当时的机器并不是“聪明”,但我领先于其他公司,甚至是公司的工程师。
现在,退休后,我修补了电子产品和Scounge/垃圾箱潜水,以丢弃电子设备和储存我的组件柜。
必须诊断出机器(我的工作),并且控件是与今天的Ardueenio相似的插头和播放模块。我鄙视它们,因为我从未学会过电子技术并构建这些电路。我的意思是,我使用80年代的森林MIMS书籍构建了一些电路,然后讲述了电子产品,现在还有一个或更多的论坛和网站和您的网站。
因此,这里是一个16岁的新学生,接近61岁。这是给您的,并不是真的要发布。
I am glad you're enjoying my site and it's helping you to learn some electronics as far as learning and exploring new things is concerned age can be never be a barrier…so do feel free to ask, and question whatever you will intriguing, I'll try my best to help you out.
你好亲爱的斯瓦格。
我感谢您与世界分享您的经验,愿您长期以来一直在帮助。
我已经使用IRF3205 MOSFET尝试了该电路,它对小型12V 1A电动机效果很好,但是当在我的踏板车上尝试它的电动机的额定值24V 28A时,它会启动,但除非我断开电源源,否则不会停止。我什至将MOSFET加倍,并且MOSFET额定值为55V 120A的结果。
拜托我需要你的帮忙
你好,阿科,
是的,您将不得不断开停止电动机的功能,以确保保证停止车辆。我希望我已经正确理解了您的问题。
感谢您在这里所做的工作。
I have tried this and it worked well for my small electric scooter as I replaced the tip122 with irf3205.
我在踏板车上安装该电路的挑战是因为我的踏板车具有霍尔传感器扭曲油门,而不是电路中的电位计。
Please how do I replace the 100k potentiometer with the hall twist throttle?
Thanks
Thanks Ako,
您可以使用以下电路:

请记住,节气门模块将需要5V DC,您可以通过7805调节器或通过任何其他逐步降低方法从主电池库中获取。
油门输出必须连接到IC2的引脚#5处的指示输入
Olá como vai? Fiz o circuito pwm com ci 555, mas a variação de velocidade quase não é percebida, o que pode ser? Obrigado.

你好
我试图掌握在Amazon / eBay上出售的速度控制器的图表和零件列表,这是一种刷的DC 10至55V可逆类型,询问的原因是我试图修复我超载的速度。
