Title (EN) ELECTRIC MOTOR, FAN, AND AIR CONDITIONER
(FR) MOTEUR ÉLECTRIQUE, VENTILATEUR ET CLIMATISEUR
(JA) 電動機、送風機、及び空気調和機
Abstract: front page image
(EN)An electric motor (1) has a rotor (2) and a stator (3). The rotor (2) has a rotor core (21) and a plurality of permanent magnets (22) fixed on the outer surface of the rotor core (21). The stator (3) has a stator core (31) having tooth portions (312) and has windings (32) wound around the stator core (31). When the minimum distance from the center of end surfaces (312a) of the tooth portions (312) to the permanent magnets (22) is denoted by t1 and the distance from ends (312c) of the tooth portions (312) to the permanent magnets (22) is denoted by t2, the electric motor (1) satisfies an equation of 1
(FR)Un moteur électrique (1) comprend un rotor (2) et un stator (3). Le rotor (2) comporte un noyau de rotor (21) et une pluralité d'aimants permanents (22) fixés sur la surface extérieure du noyau de rotor (21). Le stator (3) a un noyau de stator (31) ayant des parties de dent (312) et comporte des enroulements (32) enroulés autour du noyau de stator (31). Lorsque la distance minimale entre le centre des surfaces d'extrémité (312a) des portions de dent (312) et les aimants permanents (22) est représentée par t1 et que la distance entre les extrémités (312c) des portions de dent (312) et les aimants permanents (22) est représentées par t2, le moteur électrique (1) satisfait à l'équation 1 < t2/t1 ≤ 8.
(JA)電動機(1)は、ロータ(2)と、ステータ(3)とを有する。ロータ(2)は、ロータコア(21)とロータコア(21)の外側表面に固定された複数の永久磁石(22)とを有する。ステータ(3)は、ティース部(312)を有するステータコア(31)と、ステータコア(31)に巻回された巻線(32)とを有する。電動機(1)は、ティース部(312)の先端面(312a)の中央から永久磁石(22)までの最小距離をt1とし、ティース部(312)の端部(312c)から永久磁石(22)までの距離をt2としたときに、1<t2/t1≦8の式を満たす。
