Abstract[English]
The present disclosure relates to a chainsaw (1), comprising a guide bar (11) carrying a saw chain (9) and an electric motor (21) configured to drive the saw chain (9), the electric motor comprising windings (11) connected to an electric control arrangement (23), including an inverter (37) and a DC power supply (15) connected to a power source (13). The control arrangement is configured to switch between a driving mode, where the saw chain (9) is driven by the electric motor (21) for operation of the chainsaw (1), and a braking mode where the electric motor (21) is braked. The DC power supply (15) comprises a series switch (53) for breaking the connection between the power source (13) and the inverter (37) during the braking mode.[French]
La présente divulgation concerne une scie à chaîne (1), comprenant une barre de guidage (11) transportant une chaîne de scie (9) et un moteur électrique (21) conçu pour entraîner la chaîne de scie (9), le moteur électrique comprenant des enroulements (11) reliés à un agencement de commande électrique (23), comprenant un onduleur (37) et une alimentation électrique CC (15) reliée à une source d'alimentation (13). L'agencement de commande est conçu pour commuter entre un mode d'entraînement, dans lequel la chaîne de scie (9) est entraînée par le moteur électrique (21) pour le fonctionnement de la scie à chaîne (1), et un mode de freinage dans lequel le moteur électrique (21) freine. L'alimentation CC (15) comprend un commutateur série (53) pour rompre la connexion entre la source d'alimentation (13) et l'onduleur (37) pendant le mode de freinage.
