In medical pumps used in clinical settings—such as infusion pumps, insulin pumps, and hemodialysis machines—motors that deliver medications and blood with precision are essential. Since even the slightest deviation in flow rate directly affects patient safety, these motors must offer high precision and reliability.Furthermore, with the spread of home healthcare and growing demand for portable devices, requirements for miniaturization, quiet operation, and energy efficiency are increasing year by year. On the other hand, as miniaturization progresses, trade-offs in noise and performance are more likely to occur, making motor selection a critical factor that determines the overall performance of medical equipment. In this article, we will first outline the role of motors in medical pumps and the performance requirements they must…

A BLDC motor (Brushless DC Motors) is a motor that removes the brushes and commutator from a conventional Brushed DC motor and achieves rotation through electronic control. Due to characteristics such as long service life, low noise, and high energy efficiency, their adoption is expanding across a wide range of fields, including home appliances, Industrial equipment, and automotive components. On the other hand, there are several points to consider when implementing them, such as the need for a dedicated control circuit for operation. This article explains the basic structure and operating principles of BLDC motors, their differences from Brushed DC Motors, their advantages and considerations, and their typical applications. This information will serve as a useful reference when selecting a…

Actuators play a key role in moving machinery across a wide range of fields, including manufacturing, robotics, and medical equipment.The term “actuator” is a general term for devices that use energy sources such as electricity, hydraulics, or pneumatics to move moving parts. They are widely used in everyday scenarios, such as the opening and closing mechanisms of automatic doors and the joint drives of robotic arms. While the term “actuator” is used broadly, there are multiple types—including electric, pneumatic, and hydraulic—and their mechanisms and optimal operating ranges vary. This article provides a systematic explanation of actuators, covering everything from their basic definition and the mechanisms of each type to their typical applications. We also outline key selection criteria based on…

A geared motor is a drive unit that integrates a motor and a gearhead (reduction gear). Its key feature is the ability to achieve low-speed, high-torque output—which cannot be obtained from a motor alone—in a space-saving design.They are used across a wide range of industries, from large-scale equipment such as conveyors, food processing machinery, and industrial robots, to small precision devices like medical equipment, optical equipment, and electronic locks. Various types are available depending on the application, and selecting the right model to match the required performance and installation environment is key to ensuring stable operation. In this article, we will explain the basic mechanisms and structure of geared motors, the main types of gearheads, and key selection points to…

When performing motor selection, calculating torque is an essential step. Torque is a physical quantity that represents the magnitude of the force required to rotate an object around an axis. It is closely related to a motor’s output and rotational speed, and an incorrect calculation may prevent the equipment from operating properly. Conversely, selecting a motor with excessive specifications can lead to increased costs and space constraints, so caution is required. This article explains the basic definition of torque and the proper use of units, as well as how to apply the calculation formula “T = 9550 × P/N,” which uses output and rotational speed.We have compiled practical information ranging from the concepts of load torque and safety factors to…

“Rated output” is a term that always appears in catalogs for motors and power supply equipment. While it is an important metric for product selection, surprisingly few people may fully understand the difference between rated output and maximum output or power consumption. Rated output is a standard value indicating the output performance of the equipment guaranteed by the manufacturer. Selecting equipment without a proper understanding of this value can lead to problems such as failure due to overload, overheating, or failure to achieve the expected performance. Especially in product development involving compact motors, a proper understanding of rated output is the first step toward ensuring reliability. In this article, we will explain everything from the basic definition of rated output…

Many electrical issues in factories and offices—such as circuit breakers tripping suddenly or equipment shutting down—are caused by “overelectric current.” If left unaddressed, this can lead to serious accidents such as wiring damage or electrical fires. Particularly in facilities using industrial equipment or motors, equipment shutdowns caused by excessive electric current can affect the entire production line and potentially result in significant economic losses. For development engineers and facility managers, correctly understanding the causes of overelectric current and implementing appropriate countermeasures is essential for maintaining equipment safety and uptime. This article provides a comprehensive explanation of practical information, ranging from the basics of overcurrent to its causes and specific countermeasures.     Supervised by: C.I.

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…
