Title (EN) CONTROLLER FOR A BRUSHLESS MOTOR
(FR) DISPOSITIF DE COMMANDE POUR UN MOTEUR SANS BALAIS
Abstract: front page image
(EN)A controller for a brushless motor, the controller comprising a PWM module configured in half-bridge or full-bridge mode. The PWM module outputs control signals for controlling the excitation of a winding of the motor, and one of the duty cycle and the period of the PWM module defines a time at which the winding is commutated.
(FR)La présente invention se rapporte à un dispositif de commande pour un moteur sans balais, le dispositif de commande comprenant un module de modulation de largeur d'impulsions (PWM) configuré en mode en demi-pont ou en pont complet. Le module de modulation PWM transmet des signaux de commande permettant de commander l'excitation d'un enroulement du moteur, et le cycle de service ou la période du module de modulation PWM définit un moment pendant lequel l'enroulement est commuté.
