Rotating electric machine and manufacturing method for rotating electric machine

A manufacturing method for a rotating electric machine,

• the rotating electric machine including
• a field element that includes a magnet portion that has a plurality of magnetic poles of which polarities alternate in a circumferential direction,
• an armature that has an armature winding of multiple phases,
• a power converter that has a first electrical component that generates heat as a result of energization, and a second electrical component that generates heat as a result of energization and has a smaller amount of heat generation than the first electrical component, and is electrically connected to the armature winding,
• a first housing member that includes an end plate, and an armature-side wall portion that extends in an axial direction from the end plate and has a circular cylindrical shape, and
• a second housing member that includes a component-side wall portion that is provided on the counter-field element side in the radial direction relative to the armature-side wall portion, extends in the axial direction from the end plate, and has a circular cylindrical shape, and an overhang portion that is provided so as to be separated from the end plate in the axial direction, and extends from one end in the axial direction of the armature-side wall portion to one end in the axial direction of the component-side wall portion, wherein
• either of the field element and the armature is a rotor,
• the cylindrical portion is formed by the end plate, the armature-side wall portion, the overhang portion, and the component-side wall portion, and
• a coolant passage that has an inlet portion into which a coolant flows and an outlet portion from which the coolant flows, and connects between the inlet portion and the outlet portion in one direction along the cylindrical portion is formed in the cylindrical portion,
• the manufacturing method comprising:
• a step of fixing the armature winding on the field element side in the radial direction of the armature-side wall portion by an adhesive that is cured by heating;
• a step of assembling, on a circumferential surface of a counter-field element in the radial direction of the component-side wall portion, the first electrical component on a circumferential surface from the inlet portion to a specific position between the inlet portion and the outlet portion in the circumferential direction, and the second electrical component on a circumferential surface from the specific position to the outlet portion in the circumferential direction;
• and
• a step of forming the coolant passage by combining the first housing member to which the armature winding is fixed, and the second housing member to which the first electrical component and the second electrical component are assembled.
