Title
(EN) VIBRATION MOTOR AND APPARATUS USING THE SAME
(FR) MOTEUR VIBRANT ET APPAREIL UTILISANT CE DERNIER
Abstract
(EN) A vibration motor obtains a FAST signal when R.P.M. of the motor (101) is faster than reference speed, whereby an output-driving circuit (111) is controlled by the FAST signal to omit parts of the powering periods of respective phases. The motor thus controls the R.P.M. and increases torque ripple generated from the motor (101). As a result, vibration magnitude increases and insufficient vibration due to downsizing of the motor can be compensated by the control system. A motor driver (100) can be formed with a one chip semiconductor device (140), so that the number of exterior components is reduced and the motor can be downsized and have light weight.
(FR) L'invention concerne un moteur vibrant recevant un signal FAST lorsque le régime du moteur (101) dépasse une valeur de référence, un circuit d'attaque de sortie (111) étant commandé par le signal FAST pour omettre des parties des périodes d'alimentation des phases respectives. Ce moteur permet par conséquent de commander le régime du moteur et d'augmenter les ondulations de couple générées par le moteur (101). Ainsi, la grandeur des vibrations augmente et les vibrations insuffisantes dues aux dimensions réduites du moteur peuvent être compensées par le système de commande. Une commande de moteur (100) peut être formée à l'aide d'un dispositif semi-conducteur à puce (140), de façon que le nombre de composants extérieurs soit réduit et que le moteur ait des dimensions et un poids réduits.
