[Improvement Case] Coil Performance and Process Enhancement through Servo and Electronic Tension

[Improvement Case] Coil Performance and Process Enhancement through Servo and Electronic Tension

By using servo tension, advanced control is possible! A case where customer performance requirements were met.

We would like to introduce examples of coil performance and process improvement using servo and electronic tension. In this improvement project, the hollow coils for motors and actuators required ultra-precise aligned winding and high tension adjustment for the outer diameter specifications. By using servo tension and electronic tension that can be controlled with high precision, we were able to apply the internal standard limit tension and meet the customer's performance requirements. [Challenges] - It is necessary to determine the type and value of tension based on the customer's coil specifications. - The hollow coils for motors and actuators require ultra-precise aligned winding and high tension adjustment for the outer diameter specifications. *For more details, please refer to the PDF document or feel free to contact us.

Which specifications, such as dimensions and resistance values, should be prioritized for the winding?

Which specifications, such as dimensions and resistance values, should be prioritized for the winding?

Explain the points to consider when designing a coil, as well as the shape of the coil, the wire, and the number of turns!

When considering the coil you want to create, the productivity can vary significantly depending on which winding specifications, such as shape, resistance value, and inductance, you prioritize. In this article, we will specifically explain the points to consider when designing a coil. Coil design refers to deciding on the shape of the coil, the type of wire to use, and the number of turns, among other winding specifications. We will determine specific numerical values and create drawings. We will briefly explain the coil's shape, wire, and number of turns. *For more detailed content of the blog, please refer to the related links.

Coil used as a sensor

Coil used as a sensor

A detailed explanation of the overview of coils used as sensors and their application examples!

Coils are common components used in many electronic devices and electrical products, but they can also be utilized as sensors. This article provides an overview of how coils are used as sensors and details their applications. A coil is an electronic component shaped like a wire wound in a spiral. Generally, the wire is wound around a core made of iron or a magnetic material. By passing current through the coil, it can generate a magnetic field, and various applications can be realized by utilizing this characteristic. *For more detailed information, please refer to the related links. For further details, please check the PDF materials or feel free to contact us.*
