Rotor, method of manufacturing the same, and motor including the rotor

Abstract

The present invention relates to a motor for a vehicle and a rotor applied thereto. Provided is a rotor including a rotor core in which a plurality of rotor core members are stacked and a plurality of magnets inserted into magnet insertion holes of the rotor core, and further including fixing patterns that protrude toward the center of the magnet insertion holes from one sides of the magnet insertion holes of the rotor core members respectively disposed at an uppermost layer and a lowermost layer.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2015-0045535 filed on Mar. 31, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The invention relates to a motor for vehicles and a rotor applied to the motor. Background technique [0004] As motors for vehicles have developed to high specifications, such as high torque and high speed, the structure of the rotor assembly applied to the motor must require a robust design. Generally, an interior permanent magnet (IPM) motor applied to an interior permanent magnet (IPM) motor has a structure in which a magnet is inserted into a stacked rotor core formed by stacking a plurality of rotor core members in a disk shape. [0005] In this case, the magnet inserted into the rotor core is fixedly adhered to the magnet insertion hole by using an adhesive or the like. However, the method of fi...

AI Technical Summary

Problems solved by technology

However, the method of fixing using only an adhesive causes problems such as movement of the magnet relative to the initial installation position, generation of foreign matter due to delamination of the adhesive, and The magnet cannot be fixed due to the glass transition at high temperature caused by the deterioration of the adhesion of the adhesive that fixes the magnet

[0006] In order to solve the above problems, an adhesive capable of high temperature resistance is required, but it is difficult to apply the adhesive due to some problems in terms of cost, ensuring durability during high-speed rotation, and economic feasibility
