Title:
BRUSHLESS TYPE MOTOR AND ROTOR FOR MOTOR
Document Type and Number:
Japanese Patent JP2018068100
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor reducing the height of a compressor at a desirable degree without reducing the height of a bearing and increasing the moment of inertia.SOLUTION: The present invention relates to a rotor 2 for a brushless type motor with surface magnets 3. The rotor has an axial extension in which a shaft is inserted, the axial extension having a height greater than that of a stator package, and the axial extension also having a radial extension 9 into the bottom surface of the magnets. The radial extension has an external radius greater than or equal to the radius of the axial extension, but less than or equal to the external radius of the magnets. The axial and radial extensions are used for fixing the shaft, increasing the moment of inertia, and increasing a magnetic flux generated by the magnets, and also serve as a reference portion for the assembly of the magnets.SELECTED DRAWING: Figure 4
