🎉We can now proudly present the winners of the TAPAS Community Challenge 2018! 🎉
Congratulations to Team "Wireless Charging" (idea 56). We are really excited for all finalists and a really big thank you to all participants for your interest in this challenge!

We got over 200 submissions! 65 ideas got one or more TAPAS boards, 10 submissions were presentation-ready.
And now we have 5 finalists! YEAH 😃 The finalist's idea numbers were 40, 56, 68, 212 and 213.
What's next?
We are now preparing the next steps for you, the community. Please stay tuned!
We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!

Motor Control Voltage Minimization

Certain PWM combinations from motor control can cause excessive voltage overshoots. These overshoots together with common-mode voltage and/or voltage speeds (dV/dt) cause electrical insulation degradation on motors - leading to failure over time.

If it is possible to reduce voltages, then the electrical insulation inside motor slots can be reduced. This is equal to putting more copper inside the motor and then yield higher power ratings and efficiency.

By applying an extra dimension of voltage control to existing techniques such as space vector control, a final system should be able to run a PMSM, showing voltage improvements from before to after voltage minimization. Please see attached for more information.

    And something else...

    We are really excited to see your progress! 
    Please post the progress within your idea board submission.
    PS: We want to do a community call with you! Please use our doodle to find a date which fits best for you. :-)

    Hi Nora,

    Proposed doodle dates are not fitting well with my calendar - perhaps we can arrange a call on the 22nd of June say from 15-18 CET? I will be under high pressure to make the system before the 25th of June :)

    Hey Ruben,

    I think we can't shift the date.
    If you have any questions or annotations feel free to write an email to us everytime :-)

    Hi Ruben,

    Don't forget that the submission deadline for your presentation is on 24th of June! We are already curious to see the results of your project :-) Keep in mind that you still have time to work on the implementation of your idea after the submission!

    Please post your project visualization and all related documents within your idea board entry :-)
