Abstract

The invention discloses a cooling structure of a driving motor, belongs to the technical field of motor cooling structures, and solves the technical problem that: the service performance of an automobile is reduced due to low heat exchange efficiency between cooling liquid and a stator of a structure in the prior art. The cooling structure is suitable for cooling a stator of a new energy automobile, the driving motor comprises a casing, an inner cavity is defined by the casing to install a stator iron core and an oil injection ring, a cooling oil way is arranged in an area defined by the oil injection ring, the casing and the stator iron core, cooling liquid can flow through the stator iron core and the oil injection ring, and at least the stator core can be cooled. The invention also discloses a driving motor cooling method designed by taking the cooling structure as a unit, an oil-cooled motor and an automobile. Functions of the driving motor are perfected, and the requirement of people for high heat exchange efficiency of the cooling liquid and the stator is met.

Description

technical field [0001] The invention belongs to the technical field of motor cooling structures, and in particular relates to a cooling structure and method for a driving motor, an oil-cooled motor, and an automobile. Background technique [0002] The main drive motors of existing new energy vehicles often adopt the cooling method of casing water cooling and oil cooling, and they are all assembled through the inner and outer casings, and a cooling oil circuit is arranged around the stator core, and the cooling oil circuit surrounds the stator iron core. The core is formed, and the temperature of the end winding and the winding in the slot of the stator is reduced by reducing the temperature of the stator core. Common structures include spiral, axial detour, multi-channel parallel, etc. The inner housing and the motor stator are connected by interference or keys, so that a small air gap is left between the stator and the inner housing due to the interference fit assembly meth...
