BRUSHLESS MOTOR

PROBLEM TO BE SOLVED: To increase the adhesive strength between a rotor case and a magnet for drive and a magnet for frequency power generation, without the protrusion of an adhesive by adding a contrivance to the arrangement of the magnet for drive and the magnet for frequency power generation, in a brushless motor where the magnet for the drive and the magnet for frequency power generation are bonded to the rotor case. SOLUTION: At a rotor case 80, a first cylinder 81 and a second cylinder which is larger in bore than the first cylinder 81 and a step 83 between the first cylinder 81 and the second cylinder 82 are made, a magnet 85 for drive is bonded to the first cylinder 81, a magnet 86 for frequency power generation is bonded to the second cylinder 82, one axial end is abutted against the magnet 85 for drive, and an adhesive bank 87 is made between the magnet 86 for frequency power generation and the step 83 of the rotor case 80.
