Loaded motor test device in wide temperature environment

Abstract

The invention discloses a loaded motor test device in a wide temperature environment. The loaded motor test device comprises a bench, a temperature control device and a dynamometer. The temperature control device comprises a box body, a heater, a refrigeration device, a temperature sensor and a controller, wherein the heater, the refrigeration device, the temperature sensor and the controller are arranged in the box body. The box body is arranged on the bench. The heater and the refrigeration device are respectively used for heating and cooling the inside box body. The temperature sensor is used for detecting temperature in the box body and sending a detected temperature value to the controller. The controller is used for controlling the heater to maintain temperature constant in the box body when the temperature value reaches a first predetermined value and controlling the refrigeration device to maintain temperature constant in the box body when the temperature value reaches a second predetermined value. The dynamometer is located above the box body and is arranged on the bench. A through hole is arranged in the upper end of the box body, wherein a tested motor passes through the through hole. The lower end of the dynamometer is connected with the tested motor. According to the invention, service life and performance detection of the loaded motor in the wide temperature environment can be realized.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a testing device for a motor with load in a wide temperature environment. Background technique [0002] In aerospace, oil drilling and other industries, the performance life of motor actuators used in a wide temperature environment is one of the key core factors. At the same time, it is not easy to repair and replace at any time after one-time installation, requiring very high performance. Performance and reliability, so it is necessary to carry out ground tests of performance and life under load conditions for this type of motor actuator before it is put into application. In conventional motor detection, the load control and detection sensors used are all mature technologies, but they must be used at room temperature. Because their performance parameters and accuracy are greatly affected by temperature, the environmental limit of the current general motor detection system ...

AI Technical Summary

Problems solved by technology

In conventional motor detection, the load control and detection sensors used are all mature technologies, but they must be used at room temperature. Because their performance parameters and accuracy are greatly affected by temperature, the environmental limit of the current general motor detection system The temperature is within the range of 10°C-80°C, and it is impossible to provide motor performance testing outside this temperature range

In aerospace, oil drilling and other industries, high-temperature or low-temperature-resistant motors are often used in wide-range temperature environments. The low temperature can reach -25°C or below, and the high temperature can reach 180°C. The test temperature requirements are high, and general test equipment Unsatisfactory

In the aerospace field, there are relatively advanced supporting solutions for motor detection in a wide temperature environment, but the implementation cost is high, and often involves technical secrecy and cannot be applied in the civilian field. It is urgent to develop a low-cost, high-precision solution. High-tech, easy-to-operate, and reliable testing equipment
