Title (EN) BRUSHLESS DC MOTOR AND ELECTRIC DEVICE USING THE SAME
(FR) MOTEUR A COURANT CONTINU SANS BALAIS ET DISPOSITIF ELECTRIQUE UTILISANT CELUI-CI
Abstract:
(EN) A brush-less DC motor includes a stator assembly having drive-coils for plural phases, a rotor assembly having a permanent magnet, and a built-in printed wired board (PWB) having a driving circuit for driving the drive coils. The driving circuit includes MOSFETs powering the drive coils, gate drivers controlling the MOSFETs, and a pre-driver supplying a PWM signal to the gate drivers. The PWB includes a power module formed by unifying the MOSFETs and the gate drivers with molding resin. The power module includes a setting section which sets electrical strength of the MOSFETs.
(FR) Moteur à courant continu sans balais comprenant un ensemble de stator ayant des bobines d'entraînement pour phases multiples, un ensemble de rotor ayant un aimant permanent et une carte de câblage imprimée (PWB) intégrée ayant un circuit d'attaque pour entraîner les bobines d'entraînement. Le circuit d'attaque comprend des MOSFET alimentant les bobines d'entraînement, des gestionnaires de grille contrôlant les MOSFET et un pré-gestionnaire fournissant un signal PWM aux gestionnaires de grille. La PWB comprend un module d'alimentation formé en unifiant les MOSFET et les gestionnaires de grille avec une résine de moulage. Le module d'alimentation comprend une section de réglage qui règle la résistance électrique des MOSFET.
