The student’ scientific work often becomes the first serious project of a future specialist. Ilya Belozerov, a student at the Faculty of Radio Engineering and Electronics of Novosibirsk State Technical University (NETI), demonstrates just such a case. He is developing a special stand for balancing the rotor of an electric motor.
The project is being implemented thanks to the personal participation of Alexey Bizyaev, a teacher at NSTU-NETI, who, by attracting target students to his Prometheus design bureau, interacts with the customer company and provides real engineering tasks that meet the needs of a particular production.
The student signed a contract with the Ulan-Ude Instrument Manufacturing Association of JSC U-U PPO, which is part of the Radioelectronic Technologies concern of the Rostec state Corporation. According to the terms of the contract, he is undergoing special training at the university, acquiring knowledge and skills relevant for further professional activity at the plant. One of the types of products manufactured by the company is electric motors for various purposes. To improve the reliability of the engines, Ilya Belozerov was tasked with developing a device for balancing the rotors.
The imbalance problem arises due to the uneven distribution of mass inside the rotor of the electric motor. This phenomenon significantly impairs the performance and reliability of the engine. To solve this problem, it is necessary to develop special stands to identify the causes of vibrations and eliminate structural defects.
According to Ilya Belozerov, for the implementation of the project, several methods of measuring the imbalance were studied and the optimal methodology was chosen. The basic part of the prototype device is currently being manufactured: legs, table, guide rails, platform and walls in which the bearing will be installed. Then it is necessary to assemble the electronic component of the system, including sensors and a system for detecting imbalance using a laser. This method allows you to accurately determine the places of defects where plates will be welded in the future, which will be filled with metal to equalize the masses of the rotor.
It is planned to complete the creation of the first sample stand in the next academic year. The resulting prototype will become an almost finished product that can be tested in the production conditions of the partner plant.
Thus, the system of targeted training of NSTU-NETI students is aimed at training qualified personnel who meet the needs of enterprises in the real sector of the economy. Already in the course of their studies, students have the opportunity to apply their theoretical knowledge in practice, thereby ensuring a high level of graduates' readiness for their future profession. Upon graduation, the young specialist will receive a qualification as a designer and technologist of radio-electronic equipment, which is in demand by the Russian electronics industry.
