Optimization of parameters of quiet permanent magnet synchronous motor for linear drive of long-stroke single-stage piston compressor

The article proposes a solution to the problem of optimizing the magnetic system design of a low-speed synchronous motor with permanent magnets (PMSM) as a part of a linear drive of a single-stage piston compressor that is promising for use in compressor construction for a given law of motion of the moving part. The maximum efficiency of the electromechanical converter is used as an optimality criterion. By solving the optimization problem, the relationship between the design parameters and the energy performance of the PMSM was established in an analytical form. The substantiation of the maximum possible efficiency of the PMSM for the sinusoidal and non-sinusoidal laws of motion of the inductor is given.

PURPOSE: Obtaining a solution to the problem of optimizing the magnetic system design of a low-speed PMSM as a part of a linear drive of a single-stage reciprocating compressor for a given law of motion of the moving part that meets the criterion of maximum efficiency of an electromechanical converter.

METHODS: The methods of the theory of electromechanical energy converters, theoretical electrical engineering, mathematical modeling, optimization methods, variational, differential and integral calculus, as well as experimental methods are used.

RESULTS: The results of an experimental study of the developed prototype of a low-speed SDPM as a part of a linear drive of a long-stroke single-stage reciprocating compressor are presented.

CONCLUSION: The highest efficiency of the PMSM is achieved when the current in the armature winding changes with time in direct proportion to the speed of the inductor. To ensure this mode, it is proposed to use an open-source frequency converter, which makes it possible to implement the time dependence of the current in the armature winding in accordance with the given law of motion of the moving part. The PMSM is controlled by a frequency converter based on structural models created in the MexBios environment.
