The article explains the circuit implementation of an interesting concept of converting physical energy into electricity. Here we learn a simple method of converting or channelizing the wasted gym workout energy into useful electrical energy. The idea was requested by one of the keen members of this blog, let's know more:
Technical Specifications:
你好先生，
我是最后一年的ECE学生。
I'm willing to generate power to my college gym.
I have some idea related to that. so I need your some idea relate to that.
如何通过重量相关的锻炼机器发出权力？我们不能使用压电电晶体。
I need some idea. and one more thing I'll tell my procedure for that if any mistake arise correct me.
1.通过发电机获得交流电源
2。Gives to the rectifier
3.电池供电
4.。Use inverter for commercial use.
设计
实现上述概念实际上非常简单，因为输入能量源是明确的并且一致。
While working out in a gym, the participants are much eager to donate their physical power either to shed-of extra weight or for enhancing muscle growth. Therefore, anyway this power is meant for wasting which makes the concept much easier to achieve.
我们都知道将机械力转换为电力的最简单的方式是通过电动机，或者通过使用用于旋转电动机的力并从电动机的输出线获取电力。
The above principle can be every effectively employed here as well.
将带有滑轮/绳索和悬挂重量机构的健身房中的所有重量训练设备都可以转化为发电机。
As shown in the figure below, an arrangement may be fabricated where with an additional rope pulley mechanism a simple permanent magnet type motor can be integrated with the existing weight training machine.
当任何成员拉动并在制造时使用机器时，电机也按照推拉式方式旋转。
上述移动在整流器/控制器电路内适当地处理的电动机输出线上引起所需的电动量能量，并且最后在连接的电池上递送以用于充电。
这里可以见证另一点，通过连接放电电池，电动机将受到更大的扭矩使机构更加致命。
This would hopefully make the whole thing more challenging and enjoyable for our "body builders".
The motor pulley should be much smaller in size compared to the machine pulley, so that the rotation ratio favors maximum number of rotations over the motor pulley and helps to generate optimal power from the motor.
A simple charger/controller is shown below, which can be employed for this application too. The circuit utilizes the well known IC LM338.
The "push-pull" voltage from the motor, or the alternating voltage from the motor is first rectified by the four diodes, filtered by the capacitor and regulated to the desired battery voltage by the IC LM338 circuit.
是的，通过用皮带轮或齿轮将重物取代重量。
The motor output could be loaded with fully discharged 100ah lead acid battery
Thanks for this interesting information, I'll investigate this in detail and update the results soon…..if possible I would request you to throw some more light on the concept, we all will appreciate it.
Hello,
from what i know, most of the devices generating electricity from gym eq are using DC generators. 12/24/36 V, depending on the equipment and its potential to generate electr.
用于控制设备/踏板力的当前控制阶段是我感兴趣的部分。
I’ll try writing to the company, see if they are willing to explain.
谢谢你到目前为止的解释。
Thanks, No problem!
你好，我们又见面了，
如果我有与发电机相关的消费者，则发电机将需要特定的动量/踏板力来转动。
在串联中添加可变电阻将限制电流（电流）并降低踏板力量？或者我只是谈论废话，因为通过这种方式，它需要更多的力量？我不知道Restistist是否限制了当前的电流或通过液体消耗功率？
Hi,
添加电阻将限制电流，并通过电阻加热来消散一些电流，但踩踏将变得更加容易和光。电阻器的瓦数需要大致高，否则它可能会燃烧。
Hi Swag, how are you ?
1.电阻器的瓦数达到电路瓦数？
如果一个人通过发电机达到400W，电阻必须至少支持此值？我主要发现低瓦数电阻，400W的尺寸相当大。
请参阅链接中的表：
2。A resistor that is able to control current flow is called a rheostat, correct?
That’s right Vlad, that’s exactly why I suggested using inductors or transformers for the limiting wattage of this extent
Swag, hello,
如果我在3-24之间的发电机的变量输入电压如何始终将其调节到12V常数？使用降压 - 升压转换器，右图？但如果您有20个发电机骑自行车，则此模块很昂贵，并且您需要20个降压靴设备;大约100美元
是否有任何其他方法可以调节电压较低或更高电压的电压小于12V以始终输出12V？80％以上的效率不会损失太多的力量。
Hi Vlad, unfortunately buck boost is the only way to fulfill the requirement, there’s no other way of implementing this.
Why can’t this work with piezoelectric energy harvesters?

是的，它应该工作......
