Problems solved by technology

In addition, if the adhesive expands excessively, the part where the blowing agent is pushed away by the vaporized solvent remains as a cavity, and the density of the adhesive decreases.
Therefore, there is a problem that the adhesive strength of the adhesive decreases

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0028] [Structure of the rotor of the present embodiment]

[0029] refer to Figure 1 ~ Figure 15C The structure of the rotor 100 of this embodiment will be described.

[0030] In addition, in the specification of the present application, "rotating electric machine" is described as an overall concept including a motor (electric motor), a generator (generator), and, if necessary, a motor / generator having functions of both a motor and a generator. For example, rotating electrical machine 101 is configured as a running motor used in a hybrid vehicle or an electric vehicle.

[0031] In addition, in the specification of this application, "rotor rotation axis direction" or "axial direction" refers to the rotation axis direction of the rotor 100 (along the axis C1 (refer to figure 2 ) direction; and figure 1 in the direction parallel to the Z-axis). In addition, "circumfer...

Abstract

A rotor manufacturing method is provided with a step of evaporating a diluting solvent by: heating an adhesive to a temperature in a temperature band of not lower than a vaporization start temperatureat which the diluting solvent evaporates and lower than an expansion onset temperature; and increasing the temperature of the adhesive at a temperature increase rate lower than a temperature increaserate at which the heating is performed from a heating start temperature to the temperature in the temperature band not lower than the vaporization start temperature and lower than the expansion onsettemperature.

Description

technical field [0001] The present invention relates to a rotor manufacturing method and a rotor manufacturing device. Background technique [0002] Conventionally, a rotor manufacturing method is known in which a permanent magnet is inserted into a magnet hole portion of a rotor core. For example, Japanese Patent Application Laid-Open No. 2007-151362 discloses a method of manufacturing such a rotor. [0003] Japanese Patent Application Laid-Open No. 2007-151362 discloses a permanent magnet fixing method in which a permanent magnet is inserted into and accommodated in a storage groove of a rotor core. In this permanent magnet fixing method, first, the molten adhesive is dropped onto the surface of the permanent magnet, whereby an adhesive containing a foaming agent foamed by heating is disposed. Then, in order to cure the adhesive material and reduce the thickness of the adhesive, the adhesive material is heated and pressed with a press. Then, insert the permanent magnet ...
