Research on the Detecting Method of Motor Running State of Amusement Device Based on Infrared Thermography Technology

The motor is the source power of the amusement device. Once a failure occurs, it will not only cause damage to itself, but also lead to high-altitude retention and even casualties. The traditional method of monitoring the operating state by installing sensors is costly and complicated to implement, and a large number of existing motors cannot be installed. Therefore, there is an urgent need for quick and convenient technical means and methods for detecting the operating state of the motor. To address this issue, this study simulated various operating conditions of the amusement devices and conducted comparative tests of different load rates, different duty ratios, and different cycle durations. By comparing the temperature rise data collected by the embedded sensor in the motor with the temperature rise data collected by the external infrared thermography of the motor, the main factors affecting the difference of temperature rise between the inner and outer parts of the motor casing are obtained, and the correction value of the temperature rise difference between the inside and outside of the casing is also obtained. A way of testing motor running state by infrared thermography is proposed, which can be applied in site detection with ease.
