no. 1 Embodiment approach
[0086] Next, refer to Figure 6 , and the method for manufacturing the armature according to the first embodiment of the present invention will be described. Figure 6 It is a plan view of the laminated core 6 . also, Figure 6 In , additional marks a, b, ... p are added to the 16 magnet insertion holes 61 to distinguish each magnet insertion hole 61 .
[0087] In 1st Embodiment, 16 magnet insertion holes 61a, 61b...61p are divided into 2 groups. That is, the magnet insertion holes 61a...61d and the magnet insertion holes 61i...61l form the first group. And magnet insertion hole 61e...61h and magnet insertion hole 61m...61p are 2nd group. Such as Figure 6 As shown, the magnet insertion holes 61 belonging to the first group are arranged in a direction parallel to the rolling direction of the blanks 10 constituting the laminated core 6 . The magnet insertion holes 61 belonging to the second group are arranged in a direction perpendicular to the rolling direction of the ba...
no. 2 Embodiment approach
[0091] The method of manufacturing the armature according to the present invention is not limited to dividing the 16 magnet insertion holes 61 into two groups, and injecting the resin material 8 into each group under different temperature conditions. Alternatively, the 16 magnet insertion holes 61 may be divided into three or more groups, and the resin material 8 may be injected into each group under different temperature conditions. Therefore, in the second embodiment, if Figure 7 As shown, the 16 magnet insertion holes 61 are divided into three groups. That is, the magnet insertion holes 61b, 61c, 61j, and 61k form the first group, the magnet insertion holes 61d, 61e, 61h, 61i, 61l, 61m, 61p, and 61a form the second group, and the magnet insertion holes 61f, 61g, 61n, and 61o For group 3.
[0092] Then, the laminated core 6 is heated to 180° C. or higher in the preheating device 3 . Thereafter, the laminated core 6 was carried into the resin sealing device 4, and the tem...

Abstract
The invention provides a manufacturing method of an armature having high universality. By adopting the manufacturing method, the adverse shape of the armature, and various problems caused by the adverse shape of the armature are improved, and the method is used for all kinds of steels plates with all laminated steel cores. Permanent magnets in an unmagnetized direction are inserted in a plurality of magnet inserting holes 61 of the laminated steel cores 6, and resin materials are injected in the magnet inserting holes 61, and the resin materials are solidified in the magnet inserting holes 61, and the permanent magnet is fixedly disposed on the laminated steel core. According to the manufacturing method, the laminated steel core 6 is heated, and when the laminated steel core 6 is at a temperature in a specific temperature range, the resin materials are injected in the magnet inserting holes 61, and then the laminated steel core 6 is at the temperature in a specific temperature range different from other temperature ranges, the resin materials are injected in other magnet inserting holes 61.
Description
technical field [0001] The invention relates to a method of manufacturing an armature with permanent magnets. Background technique [0002] An armature having a structure in which permanent magnets are embedded in a laminated core such as a rotor of an IPM motor (Interior Permanent Magnet Motor) is known. Since permanent magnets are embedded in the rotor core of the IPM motor, the magnets will not fly out due to centrifugal force during the rotation of the motor, and the mechanical safety is high. In addition, the IPM motor achieves high torque with high efficiency. Therefore, the use of IPM motors as power sources for automobiles, railway vehicles, and other industries has rapidly expanded in recent years. [0003] In many cases, the rotor constituting the IPM motor inserts the permanent magnets into the magnet insertion holes formed in the laminated iron core, and then injects resin into the magnet insertion holes, cures the resin in the magnet insertion holes, and fixes...
