Application of the Ansys Electronics Desktop Software Package for Analysis of Claw-Pole Synchronous Motorâ€
Round 1
Reviewer 1 Report
Permanent Magnet Claw pole machines are difficult to analyze using 2D finite element analysis. For more accurate results it requires 3D analysis. Using an analogy with a BLDC machine with "tangential magnets" (I don't really understand which topology the authors are addressing, as no clear picture of the cross-section is presented) is not the best solution. Even if the same stator seems to be kept, the distribution of the field along the axial direction in the airgap is slightly different and this cannot be neglected. In my opinion, using scaling methods can bring more accuracy in the analysis.
The work doesn't bring anything new, neither as methods, models or approach. The authors are using a commercial software package for a classical electromagnetic analysis, including preliminary sizing and optimization. They consider that the targeted application is somehow new, without presenting the main characteristics that entitle the use of claw-pole machine.

Dear reviewer. We have read your review and agreed with your comments. Re-send the article to your review. Please pay attention to the following features of our study.
We develop a unique motor, which is not in the world practice. We mean large output power and large dimensions for this design. We have a great responsibility to the real customer, so we had to create a special design system to remove technical risks.
When developing the design system, we adapted the existing CAD system to our problem. We faced great difficulties when we tried to solve a direct three-dimensional problem. Work was almost stopped because one version of the model was calculated 18-20 hours. After replacing the three-dimensional model with an equivalent two-dimensional model, we were able to resume research and finish building the design system. The accuracy of the calculation was good. In the article, we wanted to share this practice with developers who solve similar problems.
Kind regards,
Authors
Reviewer 2 Report
Authors contribution need significant expansion in all section of the manuscript. Authors need to emphasis more results to under the machine functionalities include B-H curves hystersis and flux distribution between poles, field strenght calculations. Further torque characteristic is required with flux distribution. Authors need to explain the main advantage and disadvantage of the developed machine and its specific application. Further need to show the flux density and distribution in different cases which poles are magnetized. Abstract, conclusion and introduction need to expand with recent references.

Minor language corrections are needed.
Author Response
Dear reviewer. The authors thank you for the comments that improve our article. We agree with them. In the last version of the article we corrected the introduction. We have tried to describe in more detail the methodology that we used in the project system. We have improved the English style and added the recommended literature. Thank you again for your efforts to improve our article.
Best regards,
Bakhtiyor Kosimov
