Abstract
(EN) Provided are an electronic expansion valve (100), a control system, and a control method, comprising: a step motor (10) and a Hall sensor (3); the step motor comprises a rotor (1) and a stator (2); the rotor comprises a permanent magnet; the Hall sensor is provided on the outer periphery of the permanent magnet; the Hall sensor and rotor are arranged in the radial direction, and the stator and Hall sensor are arranged in the axial direction; the main-body part (31) of the Hall sensor is used for sensing the magnetic pole change of said permanent magnet; such a structure reduces the effect that an operating environment has on the Hall sensor when detecting a signal.
(FR) L'invention concerne un détendeur électronique (100), un système de commande et un procédé de commande, comprenant : un moteur pas à pas (10) et un capteur à effet Hall (3) ; le moteur pas à pas comprend un rotor (1) et un stator (2) ; le rotor comprend un aimant permanent ; le capteur à effet Hall est disposé sur la périphérie externe de l'aimant permanent ; le capteur à effet Hall et le rotor sont agencés dans la direction radiale, et le stator et le capteur à effet Hall sont agencés dans la direction axiale ; la partie corps principal (31) du capteur à effet Hall est utilisée pour détecter le changement de pôle magnétique de l'aimant permanent. Une telle structure permet de réduire l'effet d'un environnement opérationnel sur le capteur à effet Hall lors de la détection d'un signal.
(ZH) 一种电子膨胀阀(100)、控制系统及控制方法,包括步进电机(10)和霍尔传感器(3),步进电机包括转子(1)和定子(2),转子包括永磁体,霍尔传感器设置于永磁体的外围,霍尔传感器和转子径向排布,定子和霍尔传感器轴向排布,霍尔传感器的主体部(31)用于感应所述永磁体的磁极变化;这样的结构可以减少工作环境对于霍尔传感器在检测信号时候的影响。
