    DTC control of a PMSG?

    Greetings, I'm currently working on a project that requires a direct torque control of an electrical machine that operates in both generator and motor modes. Currently this involves an induction machine with controlled slip, however do to weight and MTO restrictions a permanent magnet...

    Mediocre vs Top Notch university

    I really like this thread. Being an entering grad student I was faced with this decision. Ultimately I decided to go with a mediocre school because it was the only one that could offer me support. It is also surrounded by top-notch industry which leads to a lot OTJ experience and knowledge...

    Need advice about leaving my current position.

    Thanks for all of the advice. I realize what I have to do, just leave and try to make the most of it. I'll leave my part time offer on the table but if the bridge gets burned, then so be it. I really don't have the time or patients anymore to tip toe through the tulips I got to many things to...

    Need advice about leaving my current position.

    Thanks for the advice. It seems pretty clear what I have to do. And no I cant afford to not work. I have an assistantship that gives me a monthly stipend. Also, do you believe I should have given more than 2 weeks (willing to extend it to 3) notice? I feel a bit "unprofessional" about that...

    Need advice about leaving my current position.

    This is not my first full time employer and I have been there about 9 months. Why can't you edit posts on this forum?

    Need advice about leaving my current position.

    My boss thinks this is the greatest project in the world and its going to change everything. I'm a bit skeptical obviously. Keep in mind, this project has gone on for over 25 years and not a single prototype built along with no major funding. The reason I don't want to wait another year is...

    meaningless greetings

    Engineers sure are a rare breed. Do any of you deal with HR people during the day? If another person tells me that I have a case of the "Mondays" I'm going to blow my brains out.

    Need advice about leaving my current position.

    Well, I plan on leaving my current job as an electromechanical engineer on a venture capital project and starting grad school this fall to eventually get my PhD. However, I'm having a lot of trouble leaving on good terms. I'm giving them written notice in person with my last date of employment...

    We have better tools, but?

    I fall into catagory #2. I'm a 22 year old electromechanical engineer with a degree in mechanical engineering doing a job that several experts should be doing. And I have to say, I completely agree with every point made in this thread. I work for an engineering firm that mostly does CAD stuff...

    How much loss of energy between power plant and house?

    I belive power transmission losses were estimated at just over 7% in the mid 90s and I doubt that would have changed much now. I have to disagree with some of the numbers listed above: -Modern Otto IC engines are 27-33% efficient under normal operating conditions. -The later of most Rankin...

    Thrust and power analysis at autorotation and windmill states.

    Im trying to analyze tandem rotors going from the typical shaft powered state(+ power) to the autorotation state(0 shaft power) and then into the windmill brake state(- power). So far I am able to analyze such a design based on information from "Principles of Helicopter Aerodynamics" up to the...

    Exceptional Power Generation Density Required.

    Sorry itsmoked but I really can't release any more information about the application. I believe what I found what I as looking for. A product from IPC LLC that may do the job. Thanks for the help.

    Exceptional Power Generation Density Required.

    You are correct I didn't, my bad. But also you can not generate much power from heat when your in an environment thats -40F.

    Very basic question: How do they stay in orbit?

    I'm not an aero engineer, Im mechanical but my take on this is energy balance. As long as a satellite has enough kinetic energy it will remain in an orbit. The mass of the object being oriented and kinetic energy contained by the orbiting object determines its radius between the two objects...

    Exceptional Power Generation Density Required.

    itsmoked, purhaps you or I are confused. The only thermoelectric generators I know of are devices that generate power from either the seeder, ovonic, or temperature gradient effect. Neither of which generates power from mechanical work.
