PROBLEM TO BE SOLVED: To provide a motor that can achieve higher output while suppressing deterioration in heat radiation property.SOLUTION: A stator 20 comprises: first and second inner peripheral side stator parts 21x and 21y each forming a Lundell type structure; and first and second outer peripheral side stator parts 31x and 31y each forming a Lundell type structure. The first and second inner peripheral side stator parts 21x and 21y are arranged at an inner peripheral side of the first and second outer peripheral side stator parts 31x and 31y, respectively. A rotor 10 comprises: inner peripheral side magnets 12 and 13 arranged so as to be opposed to an inner peripheral side of the first and second inner peripheral side stator parts 21x and 21y, respectively; and outer peripheral side magnets 14 and 15 arranged so as to be opposed to an outer peripheral side of the first and second outer peripheral side stator parts 31x and 31y, respectively. Between the first and second inner peripheral side stator parts 21x and 21y and the first and second outer peripheral side stator parts 31x and 31y, a ventilation flue S that is communicated from one side to the other side in an axial direction, of the stator 20 is provided.SELECTED DRAWING: Figure 1 【課題】放熱性の悪化を抑制しつつ、高出力化を図ることができるモータを提供する。【解決手段】ステータ２０は、ランデル型構造をなす第１及び第２内周側ステータ部２１ｘ，２１ｙと、同じくランデル型構造をなす第１及び第２外周側ステータ部３１ｘ，３１ｙとを備え、第１及び第２内周側ステータ部２１ｘ，２１ｙは、第１及び第２外周側ステータ部３１ｘ，３１ｙの内周側にそれぞれ配置される。ロータ１０は、第１及び第２内周側ステータ部２１ｘ，２１ｙの内周側にそれぞれ対向配置された内周側磁石１２，１３と、第１及び第２外周側ステータ部３１ｘ，３１ｙの外周側にそれぞれ対向配置された外周側磁石１４，１５とを備える。そして、第１及び第２内周側ステータ部２１ｘ，２１ｙと第１及び第２外周側ステータ部３１ｘ，３１ｙとの間には、ステータ２０の軸方向一側から他側にかけて連通する通風路Ｓが設けられる。【選択図】図１
