PERMANENT MAGNET SYNCHRONOUS MACHINE AND METHOD FOR MANUFACTURING PERMANENT MAGNET SYNCHRONOUS MACHINE STATOR

摘要

The permanent magnet synchronous machine according to the present invention is provided with a stator constituted by a plurality of divided core blocks linked in the rotational direction of the rotor. The plurality of divided core blocks are constituted by being provided with: a permanent magnet; a pair of teeth disposed on both sides of the permanent magnet so as to sandwich the permanent magnet in the rotational direction; and a connection tooth provided in an axial direction at an end of the pair of teeth by which the permanent magnet is sandwiched, and connecting the pair of teeth.
