Title:
MAGNETIC BEARING
Document Type and Number:
WIPO Patent Application WO/2019/163722
Kind Code:
A1
Abstract:
Provided is a magnetic bearing which is capable of increasing the electromagnetic force acting between a rotor and a stator without an accompanying increase in the size of the stator or an accompanying significant increase in the complexity in the shapes and arrangements of each of the plurality of teeth of the stator. A stator body includes: a specific connection portion that connects a series of teeth on which N number of stator coils of a stator coil group are respectively wound; and a boundary connection portion that is positioned between two stator coil groups circumferentially adjacent to each other and that connects the teeth on which are respectively wound two stator coils that respectively belong to two stator coil groups and that are adjacent to each other in the circumferential direction of a rotation axis. The length of the specific connection portion in a specific radial direction is greater than the length of the boundary connection portion in the radial direction of the rotation axis.
