Title (EN) LINEAR MOTOR SYSTEM
(FR) SYSTÈME DE MOTEUR LINÉAIRE
(JA) リニアモータシステム
Abstract:
(EN) Provided is a linear motor system that can highly efficiently drive a linear motor at a mechanical resonant frequency that incorporates a load, without the need for a sensor that detects induced voltage that changes in accordance with fluctuations in the load. A linear motor system 100 that comprises a linear motor 104 that has a winding 8 to which at least alternating current voltage is applied and a mobile element 6 to which an elastic body 23 is connected. The resonant frequency of the mobile element 6 is dependent on the elastic body 23 and the load of the linear motor 104. The linear motor system 100 also has a linear motor drive device 102 that detects a fundamental wave amplitude for the current flowing in the winding 8 and increases the phase difference between the alternating current voltage Vm and the current Im flowing in the winding 8 in accordance with increases in the fundamental wave amplitude.
(FR) L'invention concerne un système de moteur linéaire pouvant entraîner de manière très efficace un moteur linéaire à une fréquence de résonance mécanique comportant une charge, sans nécessité de recourir à un capteur pour détecter une tension induite qui change en fonction des variations de la charge. Un système de moteur linéaire (100) comprend un moteur linéaire (104) qui présente un enroulement (8) sur lequel au moins une tension de courant alternatif est appliquée, et un élément mobile (6) auquel un corps élastique (23) est relié. La fréquence de résonance de l'élément mobile (6) dépend du corps élastique (23) et de la charge du moteur linéaire (104). Le système de moteur linéaire (100) comprend également un dispositif d'entraînement (102) du moteur linéaire qui détecte une amplitude d'onde fondamentale pour le courant circulant dans l'enroulement (8), et augmente le déphasage entre la tension de courant alternatif (Vm) et le courant (Im) circulant dans l'enroulement (8) en fonction d'augmentations de l'amplitude d'onde fondamentale.
(JA) 負荷の変動に応じて変化する誘起電圧を検出するセンサを要することなく、負荷を含めた機械的な共振周波数でリニアモータを高効率に駆動し得るリニアモータシステムを提供する。リニアモータシステム100は、少なくとも交流電圧が印加される巻線8及び弾性体23が接続する可動子6を有するリニアモータ104を備え、弾性体23とリニアモータ104の負荷によって可動子6の共振周波数が変動する。そして、リニアモータシステム100は、巻線8に流れる電流の基本波振幅を検出し、基本波振幅の増加に応じて、交流電圧Vmと巻線8に流れる電流Imの位相差を大きくするリニアモータ駆動装置102を有する。
