Abstract

The invention provides a resolver mounting structure of a motor. The structure is used for a rotary transformer which includes a resolver stator and a resolver rotor in the motor. The resolver mounting structure includes a front bearing including an external race coupled to a front cover of a motor housing and an internal race coupled to one side end portion of a rotation shaft, and a rear bearingincluding an external race coupled to a rear cover of the motor housing and an internal race coupled to the other side end portion of the rotation shaft, wherein the resolver stator is coupled to thefront cover and is configured as a bearing cover for supporting the external race of the front bearing.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0163637 filed on December 2, 2016, the entire contents of which are hereby incorporated by reference in all respects. technical field [0003] The present invention relates to a motor of an electric vehicle, and more particularly to a resolver mounting structure for a motor for mounting a resolver for detecting a rotation speed and a rotation angle of the motor on a cover of a motor case. Background technique [0004] Recently, all-electric eco-friendly vehicles such as electric vehicles or fuel cell vehicles are attracting attention. Such electric eco-friendly vehicles include an electric motor (hereinafter referred to as a drive motor) for driving the vehicle instead of an internal combustion engine such as a conventional engine, and the electric motor is installed in the vehicle and obtains torque from electric energy. [0005] A drive moto...
