Japanese Patent JPS62114465.
Here are the images from what must be one of the simplest permanent magnet motors ever patented:—
These are from Japanese Patent JPS62114465. At least, that is its current classification on Espacenet (the European Patent Office, at http://worldwide.espacenet.com/), who, for whatever reason seem to like to change classifications at times. Originally they listed this patent with no "S" in its classification.
Abstract
Here is the English-language abstract of JPS62114465, quoted verbatim:—
"PURPOSE: To execute continuous rotation without requiring the supply of external energy, by using diamagnetic soft substance having the characteristic of high saturation magnetic flux density, high permeability, and the like, as rotor material.
CONSTITUTION: A motor 1 is organized with a stator 2 made of a horse-shoe type permanent magnet, and a rotor 3 provided with a rotor shaft 4. Diamagnetic soft material having the characteristic of the high saturation, high permeability, and small coercive force of an amorphous alloy including the base of cobalt and the sub material of iron, nickel, molybdenum, boron, and silicon is used for the rotor 3. Then, by the motor 1, the rotor 3 is just started and rotated from an external section at the beginning, and after that, the rotating output can be retained without requiring the supply of external energy."
Comment
It seems that if the rotor material has special enough properties, this device will work perpetually as a permanent magnet motor — or so the patent claims. Needless to say, no material like this is generally known to exist.
Why bother with this?
Of course, patents claiming to extract energy in one way or another from permanent magnets are quite numerous, and generally worthless. So why am I paying any attention to this one?
The reason is that the inventor is none other than Yasunori Takahashi. Takahashi was a major "player" in the electrical engineering industry, rising to General Manager research and development for Sony Corporation, before leaving to found his own company in 1984. In fact, since I'm doing some verbatim quoting in this post, here is his entire CV, from Infinite Energy magazine, Vol.1, No. 5/6, 1996, p35:—

Yasunori Takahashi is one of the most interesting personalities to become involved with perpetual motion or "free energy" magnet motors. I'll devote a future post to his even more provocative "Self Generating Motor".
Questions
Years ago I wrote a polite letter to one of the individuals who had endorsed the Kawai magnet motor (see the video I posted on this at https://www.youtube.com/watch?v=J61m6YY-2sY) asking for more details about its performance, etc. Needless to say, with hindsight, I got no reply, and I came to realise that any such questioning, from members of the public, is futile.
Still, I often think we would be so much further ahead, in so many areas, if only those who could answer questions fully and honestly would actually do so. Of course I realise there are many possible reasons why they don't, which I won't discuss further here.
Anyway, for what it's worth, my questions for Takahashi would be:—
1. Did you build a prototype of the motor patented in JPS62114465?
2. If so, did it really work as described?
3. If so, is it still available for examination and testing?
4. If it is no longer available, would you be prepared to specify, and supervise the construction of another prototype (assuming agreement could be reached on costs)?
5. If you didn't build a prototype, or it didn't work, what was the point of applying for, and getting the patent?
