When using inductive loads such as motors and relays, the back-EMF generated the moment the electric current is interrupted can cause serious damage to power supplies and control circuits. Appropriate countermeasures against back-EMF are essential, particularly in fields that require high reliability, such as medical equipment and industrial equipment. By correctly understanding the principles behind back EMF and grasping its specific effects on motors and power supplies, you can incorporate effective countermeasures from the design stage. To achieve safe and reliable product designs, let’s deepen our understanding of back EMF.   Supervised by: C.I.

Motors are indispensable in manufacturing lines and Industrial equipment, but heat generation during operation is an unavoidable phenomenon. However, excessive heat can shorten a motor’s lifespan and, in the worst cases, lead to serious problems such as malfunctions or fires. Motor heat generation is caused by losses such as copper loss, iron loss, and mechanical loss, each of which requires appropriate countermeasures. This article provides a comprehensive explanation of everything engineers need to know, from the mechanisms behind heat generation in motors to troubleshooting methods and effective preventive measures to stop heat generation before it happens. Through proper thermal management, we can enhance motor safety and durability and ensure the stable operation of equipment.   Supervised by: C.I. TAKIRON Corporation…

In product development involving motors, a proper understanding of the relationship between voltage and motor performance is the foundation for efficient motor selection and design. How do the motor’s speed and torque change when the applied voltage is varied, and how do these relate to electric current? Without a grasp of these fundamental characteristics, it is impossible to determine motor specifications that meet the product’s performance requirements. In recent years, in particular, interest in motors that operate stably even at low voltages has been growing, driven by increasing demand for battery-powered products such as IoT devices and portable medical equipment. In this article, we will provide a technical explanation of the relationship between motors and voltage, followed by an introduction…

In manufacturing facilities and equipment operations, sudden abnormal noises from motors can lead to serious issues such as equipment shutdowns and product defects. These noises vary widely—including “squeaking,” “grinding,” and “hissing”—and each has a different cause. Sources range from mechanical factors like bearing wear, insufficient lubrication, and debris ingress to electrical noise. In this article, we will explain the main causes of motor noise by type and introduce specific countermeasures. Furthermore, for engineers considering the purchase of new motors, we will provide a detailed explanation of the characteristics of coreless motors—which help prevent noise issues before they occur—as well as their advantages in terms of low vibration and low noise.   Supervised by: C.I.
