  • yes, I understand, is a homopolar motor. What do you think instead of this motor

    search "barmotor" youtube motor ball bearing-like whith 3 stainlless still rod, is not a rail gun !!

    not B field detected (thermal motor?)

  • THE BALL BEARING ACTS LIKE GENERATOR ?

  • @qqcreafis No, this is a Homopolar Motor, the bearings just stabilize it. He has two magnets with a copper disk between them on a rod through the bearings. You put power to the shaft and the copper disk to make it spin, or you make the shaft rotate and you can take power away. This is both a Generator and a Motor at the same time. But in the vid he shows you that it can be a motor. You need to hook a motor up to the shaft and make it spin to see how much curret it makes.

  • @NoCombustion If this was a ball bearing motor you would have to spin the shaft to start the rotation. But he is using two powerful magnets on either side of the copper disk he puts the power too. That makes this a Homopolar Motor. The proof is that it starts up all on its own when he puts the power to the copper disk.

  • @NoCombustion When he takes off the power and its still spinning it is a Generator. He quickly switches to his meter to test the current while it is still spinning. All motors are at the same time generators. But what is special about the Homopolar Generator / Motor is that it has no back EMF.

  • すごいものを見せていただきました!

    質問があります。

    計器の表示は50mVくらいだったのでしょうか。それとも500­mVまでだったのでしょうか。

    よろしくお願いします。

  • Hi, Did you make this, or is this a video of a company? I'd like to get some more specs on this. For example, are the magnets touching the axle or just the copper?

  • 全てが実験からだね。これからも公開お願いします。

  • コレ系の実験は怪しく面白いのでいろいろ今後もやっていきます。­どうぞよろしく。
