Electric Motors for Variable-Speed Drive of Lock Valves

Round 1

Reviewer 1 Report

This paper focuses on electric motors used in lock valves. The requirements are summarized. The equilibrium and moment equations are derived. Below are my suggestions.

1. I feel the beginning of Section 2 needs to refer to a Figure to better explain. 
2. Could you use English in figures and formulas?
3. Since you have built a prototype motor, could you show some measured results and compare them with analysis?

Author Response

1. After correcting the article, we decided to leave it as it is, without adding a link to the beginning of the section. It exists, but further in the text.
2. Fixed
3. In section 5, starting from line 395, 2 paragraphs were added on this matter.

Reviewer 2 Report

Improving the operational reliability of nuclear power plants, combined heat and power plants (CHP), as well as oil and gas pipelines is a priority task in the development of a variable-speed drive for lock valves used at these facilities. The paper analyzes technical requirements for such devices; the motor has been selected, its electrical equilibrium and moment equations have been obtained; recommendations for the selection of the kinematic drive scheme have been formulated. Based on the theoretical data obtained, a prototype has been developed, manufactured and tested. Generally, this is a good application paper. It can be accepted if the authors can consider the following issues:1. There are a lot of different motors in the market. Why did the authors investigate this kind of motors? 2. For figure 5, please use English in the figure. 3. What is the control method for the motor? Has the robustness discussed inside? More related works are welcome to enrich the literature review on the motor control and robustness such as Tuning of digital PID controllers using particle swarm optimization algorithm for a CAN-based DC motor subject to stochastic delays;Path Following Control of Autonomous Four-Wheel-Independent-Drive Electric Vehicles Via Second-Order Sliding Mode and Nonlinear Disturbance Observer Techniques;4. More words are welcome for the results such as figures and testing data. 5. The language should be polished as well.
