Abstract:
(EN) Disclosed is an electronic expansion valve (100), comprising a rotor (10), a stator (20) and a circuit board (31). The rotor (10) comprises a permanent magnet, and the permanent magnet comprises at least two pairs of magnetic poles; the stator (20) comprises a coil (21) and a bobbin (22), wherein the coil (21) is supported by the bobbin (22), and the bobbin (22) is disposed at the periphery of the permanent magnet. Also comprised is a Hall sensor (40), which is disposed on the periphery of the permanent magnet; the Hall sensor (40) and the coil (21) are electrically connected to the circuit board (31); the Hall sensor (40) comprises a sensing portion (41), and the sensing portion (41) is used for sensing magnetic pole change of the permanent magnet; the sensing portion (41) is always located between the two ends of the permanent magnet during the entire operating process of the rotor (10).
(FR) L'invention concerne une soupape de détente électronique (100), comprenant un rotor (10), un stator (20) et une carte de circuit imprimé (31). Le rotor (10) comprend un aimant permanent, et l'aimant permanent comprend au moins deux paires de pôles magnétiques ; le stator (20) comprend un enroulement (21) et une bobine (22), l'enroulement (21) étant soutenu par la bobine (22), et la bobine (22) étant disposée à la périphérie de l'aimant permanent. Un capteur à effet Hall (40), qui est disposé sur la périphérie de l'aimant permanent, est également présent ; le capteur à effet Hall (40) et l'enroulement (21) sont électriquement reliés à la carte de circuit imprimé (31) ; le capteur à effet Hall (40) comprend une partie de détection (41), et la partie de détection (41) est utilisée pour détecter un changement de pôle magnétique de l'aimant permanent ; la partie de détection (41) est toujours située entre les deux extrémités de l'aimant permanent pendant l'ensemble du processus de fonctionnement du rotor (10).
(ZH) 公开了一种电子膨胀阀(100),包括转子(10)、定子(20)以及电路板(31),转子(10)包括永磁体,永磁体包括至少两对磁极;定子(20)包括线圈(21)和线圈骨架(22),线圈(21)通过线圈骨架(22)支撑,线圈骨架(22)设置于永磁体外围;还包括霍尔传感器(40),霍尔传感器(40)设置于永磁体的外围,霍尔传感器(40)和线圈(21)均与电路板(31)电连接,霍尔传感器(40)包括感应部(41),感应部(41)用于感应永磁体的磁极变化;感应部(41)在转子(10)的整个运行过程中一直位于永磁体的两端部之间。
