Recently I have published my findings as "A Novel Double Rotor without Stator Electric Motor: Theoretical and Functional Aspects" (http://www.djeee.org/index.php/stage/article/14/). I wish that the central theoretical idea of this invention may be cross checked and vetted by other experts in this field. I will be immensely benefited from the experts views and opinions to pursue this further.
Hello Mr. Roy,
Thank your for linking your publication! I regret the lack of comments/drawings/pictures on the construction of your test machine as well as details on the "conventional" machine (I assume this is the same with a blocked rotor thus becoming a stator?). This has an importance for comparison purposes. The use of brushes for both parts, the additional bearings and the added complexity/cost of the shaft is increasing the risk of failure and require space that might not be useful for passing torque through a single shaft. What is the total torque density of your machine as compared to a conventional machine?
Looking forward,
Guillaume
Dear Guillaume Verez thanks for your comments. The details of the torque and rpm comparisons are already discussed in the paper. This article is a more general presentation that describes all the three broad classes of electric motors. In future, I have a plan to publish more specific comparisons on this topic.
By torque density, I am talking about "total output torque divided by the total system volume or mass", which I do not see in your paper.
Thanks Guillaume Verez for your interest. The system volume or mass was same, i.e. constant, for both the conditions of the motor, i.e. single rotor or double rotor modes, as tested in my experiment. Therefore, this may be cancelled out in comparing torque output calculation, as mentioned in my paper.
