Title:
BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JP2018117429
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a brushless motor capable of suppressing magnetic influence of a drive magnet to obtain a highly reliable position detection signal.SOLUTION: A brushless motor includes a rotor in which a drive magnet 43 and a position detection magnet 44 are fixed along a shaft direction inside a rotor case 44. Between the drive magnet 43 and the position detection magnet 44, a toric separator 45 is disposed having positioning units 45a, 45b for positioning these magnets in a circumferential direction.SELECTED DRAWING: Figure 2
