Performance testing system for new energy automobile motor

Abstract

The invention relates to a performance testing system for a new energy automobile motor, and the system comprises the following parts of a base and an electric dynamometer disposed thereon; a test bench, of which the straight portion is disposed on the base, and the vertical portion is provided with a circular hole; a bearing cooling device comprising an intermediate shaft, disposed on the left side of the vertical portion of the test bench and coaxial with the circular hole on the vertical portion of the test bench; a motor mounting member disposed on the left part of the straight portion ofthe test bench and abutted against the right side of the vertical portion, wherein the upper part of the motor mounting member is provided with a central hole coaxial with the bearing cooling device;a tested motor positioned and connected to the right side of the upper part of the motor mounting member, wherein the splined shaft of the tested motor is coupled to one end of the intermediate shaftin the bearing cooling device, and the other end of the intermediate shaft is coupled to the output shaft of the electric dynamometer; and a test environment device disposed at the right part of the straight portion of the test bench. The performance testing system for the new energy automobile motor provided by the invention can perform performance testing under different environments on new energy automobile motors.

Description

Technical field [0001] The invention relates to an electric vehicle motor, in particular to a new energy vehicle motor performance test system. Background technique [0002] With the increasing popularity of new energy vehicles, the use environment of new energy vehicles is also becoming increasingly complex. Vehicles will work in harsh environments such as high temperature, high humidity, high cold, and high altitude. The performance of the motor in this environment directly affects the performance of the vehicle. Safety, power and economy. For example, the abnormal noise of the motor at low temperature directly affects the user’s satisfaction; the problem of high-temperature demagnetization of the motor will cause the vehicle's dynamic performance to deteriorate; the insulation problem of the motor under high humidity conditions will directly affect the safety of the vehicle. Therefore, all new energy vehicle OEMs and suppliers have invested a lot of resources to conduct motor...
