Claims

[Claims for Utility Model Registration] (1) A plurality of grooves are formed radially from the center on the inner and outer circumferential surfaces of an annular stator core, and stator windings are wound in a toroidal shape in the grooves via an insulating material. An inner rotor with a rotating shaft that protrudes from the stator frame at one end is inserted into a cylindrical stator frame made by integrally molding these components from thermosetting resin, and the rotating shaft is attached to the stator frame. The outer rotor frame is supported by bearing brackets installed in stepped recesses formed on both sides of the stator, and the outer rotor frame is fixed to the protruding rotating shaft via bearings, and the inner rotor and outer rotor are mounted on the inner and outer sides of the stator. A two-rotor electric motor characterized by being held in opposing positions. (2) One side of the stator frame is a cylindrical stator frame with a bottom covered with thermosetting resin, and a stepped recess for holding a bearing and a hole for inserting a rotating shaft are provided in the center of the inner bottom surface. The inner rotor is inserted through the bearing inside to protrude the rotating shaft, and a bearing housing with a bearing attached in the center is attached to the opening side of the stator frame to support the rotating shaft, and the outer rotor is inserted into the protruding rotating shaft. 2. The two-rotor electric motor according to claim 1, wherein the rotor frame is mounted and fixed via a bearing.
