Abstract

See full text

A brushless motor includes: a rotor including a magnet; and a stator including at its center a space for placing the rotor. The rotor includes: a rotor core; and a plurality of magnets. The rotor core includes a plurality of magnet holders radially formed around a rotating shaft. The magnets are housed in the magnet holders such that the same magnetic poles of adjacent magnets face each other in a circumferential direction of the rotor core, and the stator includes a plurality of teeth formed toward the center to face the rotor. Given that a radius of curvature of an outer circumference of the rotor core is R, a width of an end of the teeth in a circumferential direction is W, and a maximum outer diameter of the rotor core is L, 0.9≦R/W≦4.2 and R
