Title:
ROTOR AND ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/176199
Kind Code:
A1
Abstract:
Provided are a rotor and an electric motor with which it is possible to increase the adhesive strength between permanent magnets and a rotor core. A rotor (3) comprises a rotor core (9), permanent magnets (11), an adhesive (16), and a rotary shaft. The adhesive (16) is positioned between the rotor core (9) and the permanent magnets (11), and fixes the permanent magnets (11) to the rotor core (9). The rotary shaft (10) is fixed to the rotor core (9), and rotates about an axis (14). The adhesive (16) includes a first adhesive layer (31) and a second adhesive layer (32). The first adhesive layer (31) and the second adhesive layer (32) are arranged one after the other in the direction of extension of the axis of the rotary shaft, and have a bottom edge (33) and a top edge (34) that are opposite one another with a distance therebetween.
