Claims

[Scope of utility model registration request]

(1) In a rotor in which a plurality of permanent magnets are arranged on the outer circumference of a cylindrical yoke, the permanent magnet has a plurality of holes drilled in the radial direction, and the yoke has a plurality of holes on the outer circumference. A rotor comprising a recess that communicates with the hole of the permanent magnet, and wherein the permanent magnet and the yoke are fixed with resin filled in the hole and the recess.

(2) The recesses on the outer peripheral surface of the yoke are provided in the form of grooves in the axial direction, and the resin filled in the plurality of groove-like recesses is integrated by annular connecting parts provided at both axial ends of the rotor. A rotor according to claim 1 of the utility model registration claim, characterized in that:

(3) Scope of Utility Model Registration Claims Paragraph 1 or 2 of providing an air escape hole during resin injection at the bottom of the recess on the outer peripheral surface of the yoke
Rotor as described in section.
