Abstract
(EN)
A magnetic bearing compressor (100), an air conditioner, and a protective air gap value setting method. The magnetic bearing compressor (100) comprises: a rotor (102), a magnetic bearing (104), a sensor (106), and a control device (108). The magnetic bearing (104) is sleeved on the rotor (102); the sensor (106) is provided on the magnetic bearing (104) and is configured to detect the distance between the rotor (102) and the sensor (106) on a preset plane; the control device (108) is configured to receive the distance value, to determine the minimum distance value and the maximum distance value between the rotor (102) and the magnetic bearing (104) according to the distance value, and to obtain the absolute value of the difference between the maximum distance value and the minimum distance value; and if the absolute value is less than or equal to a preset air gap value, the control device (108) obtains the protective air gap value according to the absolute value and a preset protection coefficient.

La présente invention concerne un compresseur à palier magnétique (100), un climatiseur et un procédé de réglage de valeur d'intervalle d'air de protection. Le compresseur à palier magnétique (100) comprend : un rotor (102), un palier magnétique (104), un capteur (106) et un dispositif de commande (108). Le palier magnétique (104) est emmanché sur le rotor (102) ; le capteur (106) est disposé sur le palier magnétique (104) et est configuré pour détecter la distance entre le rotor (102) et le capteur (106) sur un plan prédéfini ; le dispositif de commande (108) est configuré pour recevoir la valeur de distance, pour déterminer la valeur de distance minimale et la valeur de distance maximale entre le rotor (102) et le palier magnétique (104) en fonction de la valeur de distance et pour obtenir la valeur absolue de la différence entre la valeur de distance maximale et la valeur de distance minimale ; et si la valeur absolue est inférieure ou égale à une valeur d'intervalle d'air prédéfinie, le dispositif de commande (108) obtient la valeur d'intervalle d'air de protection en fonction de la valeur absolue et d'un coefficient de protection prédéfini.
