Summary:To improve stability of a rotor during rotation, reduce vibrations, and lower noise.SOLUTION: A split-type motor includes an air duct 10 and an armature module. The armature module includes a housing 21, as well as a stator assembly 22, a rotor assembly, and a PCB substrate 24 attached to the inside of the housing 21. The housing 21 has an attachment cavity in the inside, and is provided with a notch communicating with the attachment cavity. The rotor assembly includes a rotation shaft 231, a magnetic ring 232 provided for the rotation shaft 231, a first bearing 233 provided on the upper end of the rotation shaft 231, and a second bearing 234 provided on the lower end of the rotation shaft 231. The housing 21 has a first bearing chamber conforming to the first bearing 233 and a second bearing chamber conforming to the second bearing 234. An elastic member 235 is provided between the first bearing 233 and the magnetic ring 232. The air duct 10 includes an inner ring 11 and an outer ring 12 provided concentrically.SELECTED DRAWING: Figure 5 【課題】回転時のロータの安定性を向上させ、振動を低減させ、騒音を低下させる。【解決手段】分割式モータは、風道１０及び電機子モジュールを含み、電機子モジュールは、ハウジング２１と、ハウジング２１内に取り付けられるステータアセンブリ２２、ロータアセンブリ及びＰＣＢ基板２４と、を含み、ハウジング２１は、内部に取付キャビティを有し、取付キャビティに連通する切欠きが設けられ、ロータアセンブリは、回転軸２３１と、回転軸２３１に設けられる磁気リング２３２と、回転軸２３１の上端に設けられる第１軸受２３３と、回転軸２３１の下端に設けられる第２軸受２３４と、を含み、ハウジング２１は、第１軸受２３３に適合する第１軸受室と、第２軸受２３４に適合する第２軸受室と、を有し、第１軸受２３３と磁気リング２３２との間には、弾性部材２３５が設けられ、風道１０は、同心円状に設けられる内側リング１１と外側リング１２とを含む。【選択図】図５
