Abstract
A motor and a spoke-type rotor structure thereof are disclosed. The rotor structure comprises a rotor core which has a plurality of spoke-type first magnetic members. Two oblique second magnetic members arranged in a V shape are provided between every adjacent two of the first magnetic members. A radius of the rotor core is R. A length of the first magnetic member is ls. A length of the second magnetic member is lv. A length component of the second magnetic member on the radius of the rotor core is x. An included angle between the first magnetic member and the second magnetic member is β. An included angle between every adjacent two of the first magnetic members is α. The parameters satisfy:, wherein·cos(180°−β);90°+α/2<β<180°.
