Title:
SPOKE-TYPE PERMANENT-MAGNET MOTOR
Document Type and Number:
WIPO Patent Application WO/2012/134130
Kind Code:
A2
Abstract:
According to the present invention, a spoke-type permanent-magnet motor comprises: a stator having stator slots arranged radially from the center of an insertion hole and stator cores arranged radially among the stator slots; a rotor which is arranged inside or outside the stator, and which has rotor cores arranged radially in the same direction as are the stator slots and the stator cores, and permanent magnets arranged radially among the rotor cores; first coupling members which are made of nonmagnetic materials, and which are arranged at the top and bottom of the rotor along the direction of the height of the rotor; and second coupling members which are made of nonmagnetic materials and arranged so as to penetrate through the rotor cores and the first coupling member. The spoke-type permanent-magnet motor of the present invention may provide high power density, and may be easily miniaturized.
