PROBLEM TO BE SOLVED: To obtain the more compact axial-type brushless motor by constituting the motor of bearings holding a rotary shaft, supporting stages supporting the bearings and a core, and fixing rings for fixing the supporting stages and the core. SOLUTION: Supporting stages 13a and 13b support a core 4 and bearings 8a and 8b supporting a rotary shaft 1 freely rotatably. Fixing rings 14a and 14b fix the core 4 to the supporting stages 13a and 13b. A thrust plate 10 supports the rotary shaft 1 in the thrust direction. A bottom plate 11 receives the thrust plate 10 and is supported at the supporting plates 13. The more compact axial-type brushless motor can be realized by constituting the motor of the bearings 8a and 8b for supporting the core 4 and the rotary shaft 1, the supporting stages 13a and 13b for supporting the bearings 8a and 8b and the core 4 and the fixing rings 14a and 14b for fixing the core 4 in this way. |
