Japanese Inventor's Motor Uses 80% Less Power 1095

novakane007 writes "A Japanese inventor named Kohei Minato has created a new kind of motor. It uses magnetism to perpetuate the motor motion. As a result the motors uses 80% less energy than a conventional motor, while still maintaing the same horsepower. "Minato assures us that he hasn't transcended the laws of physics. The force supplying the unexplained extra power out is generated by the magnetic strength of the permanent magnets embedded in the rotor. 'I'm simply harnessing one of the four fundamental forces of nature,' he says." On top of the energy savings the motor runs cool to the touch and is significantly quieter than a tradtitionally powered fan. Sound to good to be true? Well he's already started selling the fan to a chain of convience stores in Japan. Hopefully soon the design will make it in to your home PC, allowing them to run much quieter."

    What? I wasn't quite aware that computers generated their own power yet... Also, the article says the engines are quite large- probably impossible to be able to use them in a laptop setup. Plus, anyway, power supplies are quite quiet anyway, and they don't generate their own power. The problem with the noise from computers these days is unbearably loud hard drives and harsh fans.

      You can buy pretty damned quiet PC fans, however, you're right that today's hard drives are louder than hell. Also, I'd bet that they generate a lot more case heat than they let on. That said, am I losing my mind or didn't I read back in 1993 that we'd all be using solid state hard drives by now??? Guess that was a sure thing in the days of $600 hard drives.

        Pricewatch.com tells me I can get a CompactFlash card reader for USB for under 20 USD and a 2 GB CF card for under 200 USD. There also exist adapters to plug CF cards into ATA cables. It seems that the desire for more capacity in a 3.5" desktop HD enclosure has outpaced the desire for larger persistent solid-state memory in desktop machines.

        That just goes to show how slow technology adoption rates has become. Ever since compact flash's invention and continual adoption in hardware, Hard drive volumes have increased amazingly. We went from densities of around 10gb when CF became mainstreamed to now having 250GB hd's ship in computers, and 350GB hd's available for purchase.

        That being said, none of the flash memory densities have really scaled like this, and are just being left in the dust, sadly. I'd love to have an iPod with a SD/MMC card reader so that I could exchange songs with a friend at school if they wanted me to listen to something really quickly, or so I could pull data off the iPod and put it into a computer.

        Speaking of putting an SD/MMC card into a computer, when will Dell start shipping memory card readers in their machines that have dumped floppies, or are they just going to chalk it up to rewriteable CD drives and abandon solid state memory cells altogether?

            There also exist many third party utilities [ipodlounge.com] for extracting music from iPods. These can be used to generate filenames, which the iPod often discards as it exclusively uses ID3 tags to populate its database.

        I'd love to switch to a solid-state hard drive, but the number of write cycles before it dies is way too small. I guess you might be able to get away with it if you had a few Gig of RAM so you didn't need swap and you had room for a RAMdisk-based temp/tmp folder, but just putting a Flash-drive in place of your system's hard drive will cause it to fail within a few months.

        Actually, assuming this is for real, we now have a source of free energy.

        With an input of 540 watts and an output of ~1.57 KW (when hooking the motor to a generator) all you need to do is split the output of the generator between the motor and some other load, and your generator is now powering the motor that drives it and up to ~1KW load. That's 1KW of free energy!

        I think it has a very high likelihood of being BS, but if it's not, then hell... I can't wait to see it! Live-off-the-grid time for me!

          From Gizmodo.com [gizmodo.com]

          JOEL JOHNSON -- After reading the story about Kohei Minato's super-efficient motor, reader Chris Drake wrote in with this explanation:

          All Minato's power calculations appear to be wrong (apparently it's a common mistake many scientists make); you can't measure input power using a multimeter when the current drain isn't constant. You can see his workshop in his videos - all his calculations are done using common multimeters and a desktop calculator. Minato motors use an optical sensor to "switch on" the "stator" (electromagnet) for a fraction of each RPM, so he'd need an oscilloscope and some funky math to figure out how much current the motors are really sucking up (or a stopwatch; and wait for the driving battery to go dead, then estimate based on the battery capacity). It's still a super neat idea though - which seems to boil down to "drive motors from the outside using aligned permanent magnets and momentary pulses from the stator" instead of the traditional "sick the stator in the middle" idea.

      I worked as a patent consultant briefly and in a short time saw a couple of perpetual motion schemes. The most elaborate was proposed by a bank security guard and involved a hydraulic pump and motor combined with an electric motor and generator.

      I explained that energy in a system worked like a bank account (bank guard -remember?) You put energy in and you can take it back out, but you can't get quite as much back out as you put in because there was a service charge in the form of friction. He begrudgingly understood. I complemented him on his nice drawings.

            Mod this guy up... This is a really strong magnet; and dead hard drives are an awesome source for refrigerator magnets.

            To your "how a drive ... can operate next to it"... I think this is the explanation.

            While a normal magnet

            N---S

            has a field that falls off at something like 1/R^3 or 1/R^4, you can arrange more than one that falls off even faster. I think like this:

            N---S
            S---N
            N---S
            S---N

            And extend it to 3-dimensions and it'll fall off even faster than that.
            That way the field will be super-strong next to the magnet, but super-week even a short distance away.

              Have you ever tried to erase a floppy with a magnet? I have tried on several occasions and it is harder than you might think.

              to "Randomize" the magnetic "markings" on the disk, you need a Degausser. (Gauss being the pioneering physicist on the subject of magnatism.

              A Degausser is an electromagnet that creates a magnetic field that is constantly changing. that is what you need to "Randomize" the magnetic alignment of the particles on the disk in order to erase it entirely.

              For the record, I took a full, height, five-and-a-quarter hard drive apart, (I think it was on the order of 1 GB) and there were two extremely strong magnets in the head actuator mechanism. they were so strong that you couldn't pull them apart, you had to slide them, so they were kind of offset and twist them.

              I still use them to re-magnitize screwdrivers and bits

      You are correct in your dismissal, however your calculation is only correct for DC or pure resistive loads.

      disclaimer: IANAP (I am not a Physicist)

      In an AC circuit is quite possible to measure an AC voltage and amperage which if multiplied give greater than the power input. The trick is that power is not equal to the RMS voltage times the RMS current if the voltage and current are out of phase. For example the peak current happens during off peak voltage and vice versa.
      • by Viv (54519) on Thursday April 15, 2004 @05:14PM (#8875611)
        Not quite right -- in an AC circuit, if you take ALL power into account, you'll always get equal power in and out. The key is that when the current and voltage are out of phase (as in an inductive or capacitive circuit), some of the power is "real" and some of it is "reactive". The real is measured in watts and the reactive is measured in "VAR"s. You can't use the VARs directly because they're the power that gets stored in the inductance and/or capacitance in the operation of the circuit.

        If you get a higher output power than input or a higher input power than output, it means that you forgot to check the reactive power :)

        Four laws of electrical science; there are no exceptions to these, ever:
        1. Voltage is equal to current times impedance
        2. The algebraic sum of all voltages in a loop is zero.
        3. The algebraic sum of all currents in a branch is zero.
        4. The algebraic sum of powers in a circuit is zero. (aka, power in = power out).

        If your measurements ever violate any of these laws, you either f*cked up, or you need to file a patent because you just found a way to violate a _law_ of electrical science. That's a big deal, like violating gravity :)

      The article is fubar'ed beyond belief. Ignoring for a minute the obsurd thermodynamics claims, based off of the description of the motor, it seems like he's invented a very controlable reluctance motor.

      Asside: For those who arn't EEs you can use magents to spin things in various ways: induction, rotating fields generated by coils, reluctance, etc. Reluctance motors are 10-20% more efficient they their syncronous counterparts, but tend to be limited in size, hard to manufacture, and difficult to control. A lot of research has gone in to the different ways to make the magnetic stator to make the motor easier to make, control, and scale up.

      At best he's invented a particular rotor/stator combination that creates a really odd magnetic field that he can actually control. My guess is that the motor he has made runs syncronous after spinning up and that his particualar arangement of magents makes it possible for the motor to get enough torque to spin up at non-syncronous speed (i.e. start when you plug it in, and possibly give it a spin).

      IF this does work, IF he can get the reliability to the level of syncronous motors, IF it runs at a reasonable power factor, IF its reasonably EMC, AND IF it doesn't require complicated or expensive control mechanisms, he will have a good product on his hands. This would likely be used in a lot of factories, and in HVAC systems in cars. It's probably not that useful for speed control based applications (if it's a reluctance based motor, it's running at syncrous speed) so that excludes it from replacing induction motors and DC motors, unless it's so much more efficient that adding a variable AC supply to the control equipment leaves it still more efficient.

      Honestly though, I think the countless posts here are probably right: he invented something and only THINKS it works.

    I saw a similar effect on one of my brother's contraptions. Essentially, it was a roller skate wheel that had powerful magnets embedded in it. When it was spun, the magnetic field would act on a spool of wire underneath and create a charge that went into a capacitor. When tinkering with the thing, I found that one could take a magnet and place it a small ways away and that magnet would repel the other magnets on the wheel, making the thing spin longer for the same amount of energy. Later, my brother's acquaintance found a similar effect by placing the magnet on the bar that held the wheel up. I'm guessing that the process is more similar to the latter than the former.
    As all of these sorts of posts are appended IANAP, so I could be wrong.

    I could probably make a device that could take 16 watts in and generate 300 volt-amperes (AC) out - but the volt-amperes would be almost 90 degrees out of phase, and the power factor would be less than 5%. The real power out of the device would be substantially less than 16 watts. There is no way in physics to have more than 1 watt out per watt in, "magical magnets" or no. If the device was extracting energy from the magnets, they would be depleted and the device would run down after a while. That's 2nd semester physics, basic E&M.

    Either the proponents of this device are complete incompetents, or they are complete frauds. I'm inclined to believe the latter, as incompetents tend not to have the sales skills evident in the article [japan.com]

    motors uses 80% less energy than a conventional motor

    A conventional electric motor motor uses at most 1.6 Joules of electric energy to produce 1 Joule of motion energy (German Wikipedia [wikipedia.org]). If you reduce that by 80%, you use only 0.3 Joules to produce 1 Joule... nice perpetuum mobile.

    SCAM!

    This sentence pretty much tells you this is another perpetual motion hoax:
    With the help of magnetic propulsion, it is feasible to attach a generator to the motor and produce more electric power than was put into the device. Minato says that average efficiency on his motors is about 330 percent.
    Wooo-Hooo we can replace coal, oil and nuclear by just string these things together like Christmas tree bulbs!

    The other clue that this is a scam is the entourage of bankers and investors to the demos, not physicists and engineers.
    Joining us are a middle-aged banker and his entourage from Osaka and accounting and finance consultant Yukio Funai. The banker is doing a quick review for an investment, while the rest of us just want to see if Minato's magnetic motors really work. A prototype car air conditioner cooler sitting on a bench looks like it would fit into a Toyota Corolla and quickly catches our attention

    The mystefying power of the magnet is a strange and powerful thing. People seem unable to grasp properly an invisible force that comes semingly from nowhere, leading to rampant fraud and mislabeling of properties. Just look at fraudelent "medical devices" that are nothing more than wee little magnets in a convenient strip. Do they do anything? Studies are a little hard to come by since the placebo group and study group will know almost immediately which ones they are. Even in complete isolation, it wouldn't take long before they stuck their magnet bracelet to the hospital bed, door, etc.

    Magnets, to many people, can explain anything, becuase they do not understand them properly. Just as you can not construct a perpetual motion device using magnets, however, you cannot raise efficiency using magnets as an energy source. Magnets can only raise efficiency by acting as frictionless bearings, but that is not the case for these motors. This is blatant fraud, and I cannot believe these people fell for it.

    Slashdot insults Einstein's memory by regularly posting junk science articles with his image attached. But of course, they don't actually write the articles .. or submit them .. or proofread them .. or fact check them ..

    What do they draw a paycheck for again?

    This guy is putting energy into the machine every time his magnet moves. Attach it to a fixed position say with a clamp and it would not work. Take a look at this video [lhup.edu] of Minato and then read the explanation here [lhup.edu]. You will need to search in your browser for minato because the page is long. Also you have to wait for the avi to completely download.

    Lt Col Tom Bearden (US Army, retired) has been predicting this since 1995 [cheniere.org].

    It's fascinating to read Bearden's views. He claims that what we know as Maxwell's Equations are actually gross oversimplifications, made by Heaviside, of the real Maxwell's Equations -- and that a lot of amazing physics would be possible if we would go back and exploit all the possibilities in the real Maxwell's Equations. Heaviside's "arbitrary crippling" of Maxwell is basically the reason we haven't yet colonized Alpha Centauri.

    There is a lot of overlap between Kohei Minato's research and Bearden's [google.com]. Bearden made quite recent comments about Minato's motor [netscape.com].

    By the way, Minato's invention is called the "MagMotor." Does anybody know whether this is related to the Magmotor Corp. of Massachusetts [magmotor.com]?
