Title (EN) ELECTRIC MOTOR DRIVE DEVICE AND AIR CONDITIONER
(FR) DISPOSITIF D'ENTRAÎNEMENT DE MOTEUR ÉLECTRIQUE ET CLIMATISEUR
(JA) 電動機駆動装置および空気調和機
Abstract:
(EN) The electric motor drive device (100) according to the present invention is provided with: an inverter (50) applying power to an electric motor (70); and a plurality of relays (61, 62, 63) each switching the state between a first state and a second state, thereby switching the connection state of the electric motor. At least one of the relays (61, 62, 63) switches from the first state to the second state at a timing different from the timing at which the other relays (61, 62, 63) switch from first state to the second state.
(FR) Le dispositif d'entraînement de moteur électrique (100) selon la présente invention comprend : un onduleur (50) appliquant de l'énergie à un moteur électrique (70) ; et une pluralité de relais (61, 62, 63) commutant chacun l'état entre un premier état et un second état, ce qui permet de commuter l'état de connexion du moteur électrique. Au moins l'un des relais (61, 62, 63) commute du premier état au second état à un moment différent du moment auquel les autres relais (61, 62, 63) commute du premier état au second état.
(JA) 本発明にかかる電動機駆動装置(100)は、電動機(70)に電力を印加するインバータ(50)と、各々が第1の状態と第2の状態とで状態を切替えることにより、前記電動機の結線状態を切替える複数のリレー(61,62,63)と、を備え、複数のリレー(61,62,63)のうち少なくとも1つが第1の状態から第2の状態に切替わるタイミングは、他の複数のリレー(61,62,63)が第1の状態から第2の状態に切替わるタイミングと異なる。
