“…The leakage magnetic flux can be several times greater than the useful magnetic flux if the size of the magnetic system is not correctly determined. This is unacceptable for powerful motors with large dimensions [10][11][12][13][14][15][16].…”

The article presents the method of synthesis and analysis of the brushless motor with claw-poles. The motor is designed for the pilger mill drive for manufacturing seamless tubes. The peculiarity of the drive is that electric machines of this class for high power have not yet been used in world practice. In this regard, a very thorough analysis of the designed motor is required to remove technical risks in the manufacture of prototypes. For design of this motor the synthesis system and the analysis system were developed. The synthesis system is developed on the basis of nonlinear programming methods. For the analysis, it is proposed to use the program Ansys Electronics Desktop, which implements the finite element method. The peculiarity of using this program is the need to use large computer resources. Herewith, the calculation time of the main characteristics is often not acceptable for practical calculations and takes several hours. The authors propose a simplification of the computational model without significantly reducing the accuracy of the calculation. The brushless motor with claw-poles is replaced by a brushless motor with tangential magnets. The stator designs and the magnetic fluxes of the motors are the same. The effectiveness of such a replacement is shown in the real project. Calculation time with acceptable quality is reduced to a few minutes. This approach is recommended for the creation of design systems of other types of brushless machines. This scientific research was carried out for a real customer.

The article presents the design method of brushless DC motor with claw-type poles designed for the pilger mill drive for producing seamless tubes. Motors of this class are widely used for drives of small and medium capacity, but in world practice there are no examples of the production of such engines with dimensions up to 10 meters and a power of several megawatts. The article shows the feasibility of using such large and powerful electric motors for drives operating in severe conditions. This is due to the possibility of assembling a magnetic system with high-coercive permanent magnets without additional expensive tooling. But it should be noted that the calculation of the inductor with claw-type poles is quite complex. There are great technical risks to develop an inefficient design with a small magnetic flux. The article proposes to divide the problem into 2 stages. At the first stage, the problem of determining the optimal geometry based on nonlinear programming methods is solved. The authors propose a synthesis program implemented in the Delphi. The program contains several levels of optimization and covers a large number of project situations. At the second stage, the task of analyzing the optimized motor design is implemented. We use a well-tested in practice program Ansys Electronics Desktop. At this stage, the authors are faced with the need to use powerful computer resources and a large time in a few hours to calculate one option. This is due to the fact that the construction with claw-like poles does not have 2d symmetry and it is necessary to solve a 3d field problem. The article proposes an effective method of solving this problem. The authors propose a simplification of the computational model without significantly reducing the accuracy of the calculation. A motor with claw-type poles is replaced by a motor with tangential magnets, which has a 2d symmetry and can be calculated by solving a 2d field problem. The design of the stator and the magnetic fluxes of the motor standard motor and identical twins, respectively, losses, currents and voltages are also equivalent. The effectiveness of such a replacement is shown on a real project. Calculation time at acceptable quality is reduced to several minutes. This approach is recommended for the creation of design systems of other types of machines.

Currently, metallurgical industry contains a large number of morally and physically outdated electrical equipment that requires modernization. It requires a large capital expenditure to replace it. For this reason, it is slow to implement, long-term use for the purpose of payback, and slow to withdraw from manufacturing. In this regard, the new equipment must be innovative and in many respects ahead of the existing level of development of the industry. The article suggests such a solution. To replace the existing collector motor of the pilger mill drive for the manufacturing of seamless pipes, which has been operating since 1928 and is in a critical condition, a large-sized low-speed brushless motor with a large built-in inertial mass is proposed, which has a permanent magnet magnetic system and claw-poles. Such a technical solution for drives of this class has not been used in the world. The motor eliminates the existing 120-ton flywheel, improves reliability due to contactless current supply, and reduces operating costs by eliminating excitation losses. The motor design allows its Assembly without additional tooling, which is very important for large motors with permanent magnets. To develop a unique motor, a design system consisting of a synthesis subsystem and an analysis subsystem was created. The synthesis subsystem implements multi-level single-criteria optimization. As a result of its operation, the optimal geometry is determined based on the selected criterion. The analysis system confirms the calculation reliability using simplified optimization methods and finally removes technical risks before manufacturing an industrial design. It is based on the well-developed Ansys Electronics Desktop and Ansys Icepak systems for CAE electric machines. The analysis has several stages, which includes electromagnetic and thermal analysis. It is based on the well-developed for CAE systems electric machines Ansys Electronics Desktop and Ansys Icepak. The analysis has several stages, which includes electromagnetic and thermal analysis. The effectiveness of the design system was tested on a real project that was performed for the Chelyabinsk rolling mill. This approach is recommended for the design of other similar types of brushless direct current drive.
