Motor fault simulation test platform for electric vehicle

Abstract

The invention discloses a motor fault simulation test platform for an electric vehicle, and relates to the technical field of motor test. The problem that operation parameters of a motor in different working environments cannot be tested is solved. The device specifically comprises a bottom plate, a connecting plate is arranged on the outer wall of one side of the bottom plate, a mounting platform is arranged on the outer wall of one side of the connecting plate, a dynamometer is arranged on the outer wall of the top of the mounting platform, a top plate and two side baffles are arranged on the outer wall of one side of the connecting plate, and a control panel is arranged on the outer wall of one side of each side baffle. By arranging a guide pipe and a temperature and humidity sensor, a worker can send hot air into a closed space at one side of a sealing cover through the guide pipe by virtue of hot air generation equipment, so that the temperature around a test motor is increased, and at the moment, the test motor is controlled to rotate to drive a clamping rotating shaft to rotate; and the dynamometer is enabled to test the operation condition of the test motor in a high-temperature environment, and the operation parameters are transmitted to the control panel at the same time.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a motor fault simulation test platform for electric vehicles. Background technique [0002] As the core component of the electric motorcycle, the motor’s motion state directly affects the power of the electric motorcycle. Once a failure occurs, it will not only cause insufficient power of the electric motorcycle, but also generate large noise and vibration, and even cause shutdown. Consequences, therefore, it is particularly important to carry out various fault diagnosis of electric motorcycle motors, and motor testing requires reliability testing of performance parameters such as torque, speed, voltage, and current of the motor under different external environmental conditions. In order to simulate the test environment, the motor to be tested needs to be placed in a closed test box, and the required test environment conditions are simulated in the test box. [0003] After...

Problems solved by technology

[0003] After retrieval, the Chinese patent application number is CN202010636661.9, which discloses a motor failure simulation platform for electric vehicles, including a platform base, and a first hydraulic lifting device and The second hydraulic lifting device, the opposite sides of the first hydraulic lifting device and the second hydraulic lifting device are respectively fixedly connected with the first piston rod and the second piston rod, but the above technical scheme is not equipped with a corresponding motor that can work on the motor. The mechanism for simulating the environment, so there is still the problem of not being able to test the operating parameters of the motor under different working environments
