Document Type and Number:
WIPO Patent Application WO/2020/177411
Kind Code:
A1
Abstract:
A stator and a motor and compressor comprising same; specifically, provided are a stator (1) used for an electromagnetic device. The stator (1) is in interference fit with a fixing structure, and the stator (1) comprises: first stator core units (11), the first stator core units (11) comprising at least two first boss portions (111) in interference fit with the fixing structure; and second stator core units (12), the second stator core units (12) comprising at least two second boss portions (122) in interference fit with the fixing structure. The first stator core unit (11) and the second stator core unit (12) are stacked in the direction along the central axis of the stator (1), such that the first boss portions (111) and the second boss portions (122) are at least partially offset from each other when viewed along the direction of the central axis (O). According to the stator and the motor and compressor comprising same, the vibration damping in the radial direction of the stator can be significantly enhanced, thereby effectively reducing vibration and noise. Moreover, the present invention has a simple structure, is easy to process and fabricate, and has great cost benefits.
