It is said that the power consumed by three-phase induction motors accounts for 40-50% of the world's electricity consumption, making them devices that consume a significant amount of power. In Japan, the number of motors in use, including those for household purposes, is said to be around 100 million, and it is estimated that they account for 55% of the domestic electricity consumption. When focusing on industrial applications, it is said that motors account for 75% of the electricity consumption. While changing motors to more efficient ones is highly effective for reducing power consumption, it is not easy to replace the motors themselves. It is believed that adding inverters and operating motors efficiently can lead to reductions in power consumption, but it cannot be definitively stated that power consumption can be reduced in all cases. Therefore, SIRC proposes a method to estimate the power reduction effects using IoT power sensor units. *For more detailed information, please refer to the related links.

To secure strong competitiveness and profitability, excellent productivity, manufacturing costs, and high processing quality are required. Machine tools use energy to process workpieces. In other words, machine tools can be thought of as providing energy to the workpiece, deforming and altering it. The energy input into the machine tools is converted into sound, vibration, and heat, in addition to processing, and these are considered wasted energy. Furthermore, the variation in the energy supplied to the workpiece is considered equivalent to the variation in processing quality. Electric power becomes a useful parameter for managing waste and variation. By conducting detailed power measurements of machine tools, SIRC proposes methods for managing waste and variation that were not previously visible. *For more details, you can view the related links.

Almost all factories have a process for heating workpieces, and the temperature is an important parameter. Various processing methods are employed by heating the workpieces, utilizing phase changes between solid, liquid, and gas due to temperature, changes in physical parameters such as expansion and contraction due to temperature changes, and chemical changes caused by temperature. Although heaters are often thought to be usable semi-permanently due to their lack of moving parts, they are actually components that deteriorate due to expansion and contraction from temperature changes and oxidation at high temperatures. When a heater deteriorates, it can break, but even if one out of three heaters breaks, current will still flow through the remaining two, making it difficult to detect the breakage. SIRC proposes a method for detecting heater breakage by measuring power factor, as well as its application in detecting phase loss operation in inverters. *For more detailed information, please refer to the related links.
