Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2022169263
Kind Code:
A
Abstract:
To effectively suppress the temperature rise of a coil end and prevent deterioration of the insulation of the coil.SOLUTION: A stator of a rotary electric machine includes a stator core 11 having a plurality of teeth 112, a coil 12 wound around the plurality of teeth 112, and a heat transfer element 13 that transfers heat from the coil 12 to the stator core 11. The coil 12 has a coil end 121 protruding axially from the stator core 11. The heat transfer element 13 is arranged to contact each of an inner surface 121a, which is an inner surface of the coil end 121, and the stator core 11. The heat transfer element 13 has: a plurality of conductive members 130 arranged along a direction orthogonal to a radial direction of the stator core 11; and insulation layers 140 formed respectively between the plurality of conductive members 130.SELECTED DRAWING: Figure 6
