た。 In this type of conventional device, as shown in FIG. A storage tube j for a rotation detection sensor i that closely opposes the permanent magnet rotor h is attached to the periphery of the bottom surface f of the motor case e with screws or adhesive. The rotation detection sensor i detects the position of the rotor h, and is generally provided according to the number of phases of the stator winding a, and the output of the rotation detection sensor i detects the position of the corresponding stator winding a. This determines the excitation period. However, in the conventional device, there are no positional restrictions between the stator core b around which the stator winding a is wound and the bearing sleeve d, and between the bearing sleeve d and the holding cylinder j of the rotation detection sensor i. However, there is a drawback that these relationships must be taken into consideration during assembly, and it is extremely difficult to precisely attach the rotation detection sensor i to the corresponding position of the stator winding a, making it impossible to improve the wah performance.

ている。 The present invention has been devised in view of these points, and one embodiment of the present invention will be described below with reference to FIGS. 2 and 3. 1 is a metal motor case formed by drawing an iron plate. 2 is a bearing sleeve provided at the center of the bottom surface 3 of the motor case, and its collar 2' is connected by a runner 5 to a plurality of holding cylinders 4 provided at equal intervals on the peripheral edge of the bottom surface 3, and is made by injection molding of resin. It is formed integrally with the motor case 1. In this case, the bearing sleeve 2 and each holding cylinder 4 are prevented from rotating by filling the small holes 6 and 7 in the bottom surface 3 with resin, and the outer periphery of the bearing sleeve 2 has a protrusion for regulating the engagement position of the stator core 8. A groove 11 provided at the edge of the central hole 10 of the stator core 8 is fitted into the protruding portion 9 to determine the engagement position of the stator core 8 to the bearing sleeve 2. Regulated. On the other hand, a rotation detection sensor 13 is insert-molded in each holding cylinder 4 to be placed close to the permanent magnet rotor 12 during injection molding. Therefore, the engagement position of the stator core 8 is regulated by the protrusion 9 of the bearing sleeve 2, and the bearing sleeve 2 and the holding cylinder 4 in which the rotation detection sensor 13 is insert-molded are in a predetermined relationship. , the stator winding 14 wound around the stator core 8 and the rotation detection sensor 13 can be arranged in a constant relationship. A bearing 15 is press-fitted into the inner periphery of the bearing sleeve 2.

のワウ性能を向上することができる。 As described above, according to the present invention, a plurality of holding cylinders and a bearing sleeve in which rotation detection sensors that closely oppose a permanent magnet rotor are insert-molded are integrally formed in a metal motor case by resin injection molding. The relationship between the rotation detection sensor and the bearing sleeve can be determined, and the engagement position of the stator core on the outer periphery of the bearing sleeve is regulated, and the relationship between the bearing sleeve and the stator core, that is, the stator wound around the stator core, can be determined. There is a certain relationship with the winding. Therefore, the stator winding and the rotation detection sensor can be set in a constant relationship around the bearing sleeve, and the wow performance of the permanent magnet rotor can be improved.
