摘要

A permanent magnet synchronous machine includes a stator including a plurality of split core blocks that are continuously arranged in a rotation direction of a rotor. The plurality of split core blocks each includes: a permanent magnet; a pair of teeth arranged on both ends of the permanent magnet so as to sandwich the permanent magnet in the rotation direction; and connection teeth, which are provided on axial end portions of the pair of teeth sandwiching the permanent magnet, and are configured to connect the pair of teeth.
