Self Contained Power Source?

Posted by ryuzaki0 on from the magnets-and-fusion-but-can-they-fit-in-my-laptop dept.

McOSEN writes "Your Server Cabinet could have a 100% self sustained power source. It's called Parallel Path Technology and it's being coined as a revolution in the magnetic motor industry. From Segways to Vacuum cleaners to Server Cabinets. The article talks about the technology but doesn't exactly lay out specifics."

    I love how the "Lab" in the picture looks a whole lot like a kitchen.

    Yeah, it's bogus.

    If you like exotic motor designs, check out these "thin gap" motors. These brushless permanent magnet motors can reach 90% efficiency, which is very impressive. The windings are made from thin copper plates rather than round wires. These are real. You can order them.

    There's some interesting work going on in motor electromagnetics, but the "greater than 100%" motor probably isn't it.

  3. 100% *increase* in efficiency? by toybuilder · · Score: 4, Interesting
    Perhaps what was originally claimed is that the power efficiency of the motor is improved by more than 100% over conventional motor designs. TFA doesn't claim that the output motor power exceeds the input electrical power - instead, it states that there is better containment of flux leading to more motive force:
    Testing and Finite Element Analysis show that the Parallel Path system indeed manages to not only increase the magnetic flux in the core by a factor of four over conventional electric motors, but manipulate the flux to act in the direction of motion, generating considerably more motive power than conventional motors.


    Is it reasonable to assume you can get more output power with better efficiency? Try this article titled
    Increase Efficiency 10 Percent and Double Output:

    Improvements in motor efficiency also mean improvements (increases) in continuous torque ratings and reduction in dissipated power. Continuous torque ratings of any electric motor are limited by the internal losses (dissipated power) in a motor which produces heat. Any electric motor's performance is limited to its ability or inability to store and dissipate heat. Face mounting precision motors on recognized aluminum heat sinks have become an important procedure for specifying performance as described in NEMA's ICS16 (step and servo motor) standard. The table below illustrates this condition.

    Power-Watts
    Efficiency In Out Dissipated
    80% 100 80 20
    90% 100 90 10
    90% 200 180 20

    By increasing power efficiency 10%, output power is more than doubled (180/80), while maintaining constant heat loss. This is a 125% improvement in output power and motor shaft speed at rated load. The power consumption does not increase because it is tied to the line-to-line input current squared and multiplied by the hot line-to-line resistance (I2R).


    I think the original poster/editor misunderstood the original claim...
