Surface-mounted motor rotor, permanent magnet motor, compressor

Abstract

The utility model provides a kind of surface-mounted motor rotor, permanent magnet motor, compressor, surface-mounted motor rotor, including rotor core and the multiple magnetic tiles of surface-mounted on the outer circumferential wall surface or inner circumferential wall surface of rotor core, multiple magnetic tiles are sequentially arranged around the circumferential direction of rotor core, magnetic tile includes N pole magnetic tile and S pole magnetic tile, N pole magnetic tile and rotor core between there is first positioning structure, S pole magnetic tile and rotor core between there is second positioning structure, first positioning structure includes the first positioning pin and first positioning hole of adaptive plug-in, second positioning structure includes the second positioning pin and second positioning hole of adaptive plug-in, the shape and / or size of first positioning pin and second positioning pin are different.The utility model improves magnetic tile positioning precision, magnetic tile is not easy to loosen and fall off, improves the long-term reliability and stability of motor, through shape or size difference ensures that magnetic tile can only be installed in correct position, effectively prevents magnetic tile polarity to be installed wrong.
