摘要 |
<P>PROBLEM TO BE SOLVED: To provide a brushless motor having high volumetric efficiency. <P>SOLUTION: A brushless motor includes: a rotor frame 11 that is rotatable around a shaft and has an inner wall surface; an annular magnet 12 that is mounted on the inner wall surface of the rotor frame 11; and a stator that is arranged on an inner circumferential side of the rotor frame 11 so as to face the magnet 12 and generates a field that rotates the magnet 12. The stator has: a plurality of laminated plate-like bodies 51; and end plates 52a and 52b that are overlaid on respective planes 51a and 51b of the plate-like bodies 51. Each of the end plates 52a and 52b has: a main body 101; and an outer circumferential edge 102 that is provided at an outer circumferential end of the main body 101 and is bent so as to form a right angle or an obtuse angle with the main body 101. <P>COPYRIGHT: (C)2012,JPO&INPIT |
