For linear motor system, which is an electromechanical multi-parameter, strong coupling, multi-variable, strong non-linear system, the fact that the system control is difficult to carry out is becoming increasingly prominent. This paper proposes an analysis of relative weights of various factors for thrust fluctuations in permanent magnet synchronous linear motor (PMSLM) based on the Fuzzy Analytic...
In this paper, computer aided design (CAD) software of permanent magnet synchronous motor (PMSM) is drawn up. In the designed software, the interface between the ANSYS software and C ++ program is established so that the users of the software, who are strange to ANSYS, can make use of the ANSYS to calculate electromagnetic field of the PMSM. What the users do is only to input motor parameters, and...
Permanent magnet (PM) synchronous motor has the magnet devices with variable shapes and location, so the electromagnetic field in PM synchronous motor is more complex. Finite element method (FEM) provides an accurate means of determining the electromagnetic field distribution, with due account magnetic saturation characteristics. With the ANSYS, the distribution of electromagnetic field in PM synchronous...
We employ the special function of wavelet transform that can extract the characteristics of singular signals, as to the thrust fluctuation in the direct drive linear servo system, to process wavelet analysis and research on the thrust fluctuation in permanent-magnet synchronous linear motor servo system, and it finally proves that we can observe the velocity variation of a machine tool worktable by...
