Document Type and Number:
Japanese Patent JP2014165930
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a highly efficient brushless motor capable of downsizing and effectively utilizing magnetic flux of a rotor magnet.SOLUTION: A rotor 100 includes: a rotor magnet 103; a pair of rotor yokes 104, 105 on which a dent into which one end part in an axial direction of the rotor magnet 103 is buried is formed; and a pair of magnetic pole parts 106, 107 each of which has a roughly cylindrical shape of a structure in which a plurality of tabular magnetic materials are laminated in an axial direction and is in contact with an outer circumference of each of the rotor yokes 104, 105.
