The present invention relates to a hub-type electric drive device in which a motor is incorporated in a housing having a motor housing function. The hub-type electric drive device according to the present invention comprises: a housing consisting of a cup-shaped rim and a cover part of which the outer peripheral part is coupled to an opening part of the rim; a motor shaft having two end portions fixed to a body outside the housing; a first bearing and a second bearing which are provided in through-holes formed in the centers of the rim and the cover part, respectively, and which support the housing such that the housing can rotate about the motor shaft; and a brushless direct current (BLDC) motor built in the interior of the housing so that the housing rotates about a motor shaft, the brushless direct current motor comprising: a rotor in which a back yoke and a magnet are laminated on the cylindrical inner wall of the rim; and a stator having an outer peripheral portion facing the magnet of the rotor with an air gap therebetween and a central portion fixedly coupled to the outer periphery of a motor shaft for applying a rotating magnetic field to the rotor, the stator having a plurality of teeth radially extending on the outer periphery of an annular yoke, the teeth extending radially from the outer periphery of the annular yoke, the teeth extending radially from the outer periphery of the annular yoke, and the teeth extending radially from the outer periphery of the annular yoke. An inner wheel combined with a motor shaft is connected with the inner side of the annular yoke through a plurality of connecting ribs to form an integrated core frame.

    本发明涉及在具备马达壳体作用的外壳内部内置有马达的轮毂型电动式驱动装置。本发明的轮毂型电动式驱动装置包括:外壳,由轮圈和罩部组成,上述轮圈形成杯状,上述罩部的外周部与上述轮圈的开口部相结合;马达轴,两端部固定设置在上述外壳的外部的本体;第一轴承及第二轴承,分别设置于在上述轮圈和罩部的中心所形成的各个贯通孔,以使得外壳能够将马达轴作为中心进行旋转的方式支撑外壳;以及无刷直流(BLDC)马达,内置在上述外壳的内部,使得外壳以马达轴为中心进行旋转,上述无刷直流马达包括:转子,在上述轮圈的圆筒形内壁由背轭和磁铁层叠而成;以及定子,外周部与上述转子的磁铁以留有气隙的方式相向,中心部固定结合在马达轴的外周,用于向上述转子施加旋转磁场,在上述定子中,多个齿在环形轭的外周沿着放射状延伸,使得与马达轴相结合的内轮通过多个连接筋与上述环形轭的内侧相连接来形成一体型芯框架。
