Thread: The Toy Build

  1. #11
    I got the new ceramic bearing in but still waiting on magnets.

    Here are some pics of the redesigned wheel which has one bearing in the middle. It is printed to have some filler in the bottom and a bearing cap that presses on after you install the bearing so it is set in the middle exactly.

    Hi Richard,
    I should have said it's dimension in the first place but it is 8 X 22 X 7 mm.

    Here is a link. They don't say the RPM rating but it is intended for skateboards. In this application there will be practically no load on it.

    Careful Richard,

    Higher rated speeds usually come with a high ABEC rating.
    From what I can understand this is an ABEC1 bearing.
    Not rated for a ZFM. (doesnt mean it wont work though)
    Abundance of caution does no harm.

    Hi Richard,

    ABEC 1 has the lowest tolerance and hence play in the balls and race.
    At high speed you will have more vibration compared to a rated bearing for the purpose.
    Vibration = more heat and more wear.
    A Typical Spindle motor will operate 10,000RPM+ and usually has ABEC 5 or higher.

    In saying that these are for motors under big loads in all directions at higher speeds.
    The ZFM is the Zero Force Motor that is all the rage at the moment.
    In its current form speed is king and its dong 10k+.

    Skate bearings are designed for skating which is relatively low speed, hence most are not ABEC rated.

    Now it may not be so relevant to the motors/energisers built here because they are under such little load.
    However the bearings are so important to the build it does become important to research what bearings you need.

    How are you planning to reach 200HP?

    John.

My understanding of the ABEC series is the higher the number, the higher the precision of the bearing balls and races. Actually, my ultimate goal is a 200 HP @ 1800rpm motor for an airplane with a very quiet 6 bladed prop so I will be experimenting more with high torque/low rpm.
    Cant spend it when your dead.

    Hey guys I just shot a quick peek at the machine using that bearing. It's actually not the wheel pictured previously but another version where I put the original 1/4 x 1/8 magnets back with the new bearing.

    Hello Group,
    I have been tinkering away on this build in the background and I think I have settled on the final version. I decided to run it on minimal power and use it primarily as a small cell charger for things like AAA, AA, 9v and such. I have an LED headlamp that uses three AAA batteries and I have been charging them on this machine and using them in the headlamp to see if it is a good quality power and so far it works great. With this build you could easily run this thing from a very small solar panel or a small battery. It generally uses between 10-20ma depending on the charge load.

    Have a look at the video below if your interested:

    I will get the files together and make them available for download soon----Bob

    Hey Bob,
    That was excellent video and not to mention your neat set up of the charger.
    However, i would like to stress on the gist of the switching mechanism and its implications to Radiant Electricity on how it is harnessed.. no body seems to co-relate its production as shown by John bedini. JB always maintained to encourage people to learn what the trigger did.. and at times when the trigger apparently not present, the form of the Radiant also changed.
    Dough konehead used sismilar reed switch triggering of the Inductive coils..
    but these are two distinct ways of the forms of the Radiant Electricity.

    Hi Farady,
    Glad you like it. Look this is a learning tool not a masterpiece. I have made this in it's simplest form on purpose and presented it as a "Toy" for a reason. I am well aware how these circuits work and have shown many times over just about every iteration of them. What I am trying to get you to understand is that this model is not supposed to explain all the mysteries that can be found. I may sound like I am angry with you but I am not, I just don't like your hinting that I do not understand something and warding off others from fundamental knowledge.

    I would encourage you to go look at figure 1 of this patent and go ahead and read the operational description, then tell me it's misunderstood.

    Hi Bob,

    You're having way too much fun with that 3-D printer!!

    Enjoyed the video. That's a pretty sweet and novel little machine. I like that it switches without transistors and draws so little current. Looks like it might be able to go over unity?
    Gary Hammond,
