ラジアルコアタイプダブルローター方式のBLDCモーター及びその製造方法(BrushlessDirectCurrentMotorofRadialCoreTypeHavingaStructureofDoubleRotorsandMethodforMakingtheSame)
Document Type and Number:
Japanese Patent JP2005521378
Kind Code:
A
Abstract:
A radial core type double rotor brushless direct-current motor is provided in which a double rotor structure is employed with inner and outer rotors which are doubly disposed and thus a stator core is completely divided. The motor includes a rotational shaft which is rotatably mounted on a housing of an apparatus, cylindrical inner and outer yokes which are rotatably mounted on the center of the housing, inner and outer rotors including a number of magnets which are mounted with the opposing polarities on the outer surface of the inner yoke and the inner surface of the outer yoke, and a number of cores assemblies which are installed between the inner and outer rotors in which a number of coils are wound around a number of division type cores, respectively.
