| Summary: | Currently, the metallurgical production contains a large number
of morally and physically outdated electrical equipment that
requires modernization. Large capital expenditures are required to
replace it. For this reason, it is slow to implement, long-term use
for the purpose of payback, and slowly decommissioned. In this
regard, the new equipment should be innovative and in many ways
ahead of the existing level of development of the industry. The
article offers such a solution for the company PJSC «Chelyabinsk
pipe rolling plant». To replace the existing collector motor of the
pilger mill drive for the manufacture of seamless pipes, which has
been operating since 1928 and is in critical condition, a large-size
low-speed valve motor with a large built-in inertial mass, having a
permanent magnet magnetic system and claw-poles, is proposed
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 critical condition. 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 design of the engine allows
its assembly without additional technological equipment, which
is very important for large engines 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 work, the optimal geometry is determined according
to the selected criterion. The analysis system confirms the accuracy
of the calculation using simplified optimization methods and
finally removes technical risks before manufacturing an industrial
design. It is based on the Ansys Electronics Desktop and Ansys
Icepak systems that are well-developed for CAE electric machines.
The analysis has several stages and includes electromagnetic and
thermal analysis. The proposed design system is tested on a real
project and implemented as a calculation of the magnetic and
thermal state with dynamic load in JSC «Russian electric motors». |
