Abstract
The invention discloses a temperature rise testing method and device. The temperature rise testing device comprises: a temperature testing device for testing environment temperature; a voltage regulating device which is electrically connected with a tested motor and used for regulating an input voltage of the tested motor to a target test voltage; and a loading device which is electrically connecting with the tested motor and used for regulating water discharge pressure of a water pump to target test pressure, wherein the temperature testing device is further used for testing first temperatureof the tested motor after the operation of the tested motor meets a preset condition to obtain a temperature rise value of the tested motor according to the environment temperature and the first temperature. Through the device disclosed by the invention, the technical problems that during the temperature rise testing of the motor, the motor needs to be installed in a car washing machine to test the temperature rise under a rated load and the testing efficiency is low are solved.
Description
technical field [0001] The invention relates to the field of motor testing, in particular to a temperature rise testing method and device. Background technique [0002] At present, the motor used in the car washing machine often reports abnormal temperature rise. In the existing technology, in the temperature rise test of the motor, the motor needs to be installed in the car washer to test the temperature rise under the rated load, which leads to low inspection efficiency. The problem of inconvenient operation seriously affects the efficiency and timeliness of the motor's factory inspection. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiment of the present invention provides a temperature rise test method and device to at least solve the problem of low inspection efficiency due to the need to install the motor in a car washing machine to test the temperature rise under rated load in the temperatu...
