Description
Summary:This paper deals with the influence of design parameters and dc link voltage on dynamic performance of slotless double-sided permanent magnet linear synchronous motor (PMLSM). Generally, the dc link voltage is not a design target to motor designers because of a fixed power by commercial voltage. However, in this paper, we will consider the dc link voltage from a different point of view for system efficiency and optimum dynamic performance. As the first procedure, the design parameters of the PMLSM are derived by electromagnetic analysis considering space harmonics. And then the dc link voltage is defined by d - q transformed electrical dynamic equation and the design parameters according to switching scheme of voltage source inverter to satisfy the required mover speed and thrust. Finally, experimental verification for dynamic characteristic is performed by field orient speed control using design parameters according to the dc link voltage. Therefore, this paper can offer motor designers an insight for the effect of design parameters and dc link voltage on dynamic performance. The electromagnetic field analysis and dynamic characteristics are verified through the finite element method and experiment result, respectively.
