A control circuit that activates and deactivates a motor start winding at different motor rpm trip points provides improved accuracy in the trip points by automatically compensating for changes in motor current caused by variations in line voltage and motor winding temperature.
Cette invention concerne un circuit de commande qui alimente et met hors tension l'enroulement de démarrage d'un moteur à différents régimes avec une précision accrue grâce à une compensation automatique des variations de l'alimentation dues aux fluctuations de la tension du réseau et de la température de l'enroulement du moteur.
