Product handling is carried out by the conveyor belts, which are moved by one or more electric motors. Hot products heat up the rollers of conveyor belt, which in turn affect the motor shaft temperature and a reduction in motor performance is observed. To overcome this overheating problem, a novel solar‐powered master‐slave arrangement of motors is proposed, which is operated by a robotic arm‐based motor shifting mechanism controlled by an industry standard IEEE 1149.1 specification‐based mixed signal embedded controller C8051F226DK. Another embedded controller of Nuvoton's N76E003AT20 is used for the temperature detection. The speed of master‐slave motors is controlled by a PWM technique. The indigenously developed hardware prototype of the proposed system extracted 11.38% more solar energy than conventional supply and reported an encouraging 52.69% energy saving during the product handling on conveyor belt. As compared to the traditional methods, the experimental work achieved higher temperature reduction of the motor up to 34.26% and guaranteed the safe operation of motor. The master‐slave technique, first of its kind, utilizes solar power for the motor operation during the cooling process. The proposed motor cooling approach is free from air, liquid, and PCM (phase‐changing material)‐based cooling. Thus, the work does not face any leakage problems and health hazards due to the wastage of water, oil and other costly and toxic cooling materials. Additionally, the motors are used with their original dimensions without any changes in motor casing. These different factors make the work competitive among other motor cooling options.

基于新型太阳能主从电动机的节能冷却方法，用于输送系统的电动机

产品的处理由传送带完成，传送带由一个或多个电动机移动。热的产品会加热传送带的辊子，进而影响电机轴温度，并观察到电机性能下降。为了克服这个过热问题，提出了一种新颖的太阳能主从电动机装置，该装置由基于工业标准IEEE 1149.1规范的混合信号嵌入式控制器C8051F226DK控制的基于机械手的电动机换挡机构操作。Nuvoton N76E003AT20的另一个嵌入式控制器用于温度检测。主从电动机的速度由PWM技术控制。拟议系统的本地开发硬件原型提取了11。太阳能比传统电源多38％，并报告在传送带上搬运产品期间节省了令人鼓舞的52.69％的能源。与传统方法相比，实验工作使电动机的温度降低更高，高达34.26％，并保证了电动机的安全运行。首先，主从技术在冷却过程中利用太阳能来使电动机运行。拟议的电机冷却方法无需空气，液体和基于PCM（相变材料）的冷却。因此，由于水，油和其他昂贵且有毒的冷却材料的浪费，作业不会面临任何泄漏问题和健康危害。另外，电动机按其原始尺寸使用，电动机外壳没有任何变化。
