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...
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...
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...
Greetings,
I am in the process of determining what kind of generation system is best for an application. The application is in an environment that has fluctating temperatures from -60F to 110F. My question is, does anyone know of a generator product or technology that has the capability of...
I'm trying to create some models based on vector loops. However this a new concept for me and Im having a hard time finding a lot of imformation about it. Has anyone here used vector loops before and can point me in the direction of a website, reference, or possibly give me a quick summary of...
Hello All,
Im a first time poster that is having a lot of trouble with some mathematical modeling. Im currently working on a school project where I am optimizing a gerotor MOTOR for the greatest amount of displacement per rotation of the shaft. I have found many volumetric equations in many...
