Dynamo

Dynamo
Product Introduction
Our coreless dynamo is able to not only attain “smooth rotation”, but also having a “flexible design customization.”
Its ironless structure enables it to start rotating even with minimal force under certain conditions.
Furthermore, by leveraging our strength in custom design, we are able to offer flexible solutions in dimensional size and height.
A simulation confirms that some models possess a power generation capacity of 6V/3W (equivalent to a 10Ω load), making them suitable for use as a standard bicycle LED lighting.

Assumed Applications

  • Bicycle LED
  • Small Wind Turbine
  • Exercise Bike Generator
  • Emergency Preparedness Supplies
  • Camping Gear

HOW TO CHOOSE AN INDUSTRIAL & AUTOMATION MOTOR | AN EXPLANATION OF THE CHARACTERISTICS OF EACH TYPE AND SELECTION CRITERIA BY APPLICATION
HOW TO CHOOSE AN INDUSTRIAL & AUTOMATION MOTOR | AN EXPLANATION OF THE CHARACTERISTICS OF EACH TYPE AND SELECTION CRITERIA BY APPLICATION

Industrial motors are used as power sources for a wide range of equipment, including conveyor systems, robots, and medical equipment. However, with so many types available—such as DC motors, AC motors, and Brushless motors—it’s not uncommon for design and procurement personnel to struggle with the question, “How do I choose the right motor for my application?” Motor selection can result in an inability to achieve the required torque or rotational speed, which could lead to reduced equipment performance and increased costs. To choose the right product, it is important to understand the characteristics of each type and comprehensively compare factors such as output, size, durability, and control performance. In this article, we will outline the main types and characteristics of…

WHAT IS A DYNAMO? AN EXPLANATION RANGING FROM ITS MECHANISM AND RELATIONSHIP TO MOTORS TO ITS APPLICATIONS IN REGENERATIVE BRAKING AND POWER GENERATION
WHAT IS A DYNAMO? AN EXPLANATION RANGING FROM ITS MECHANISM AND RELATIONSHIP TO MOTORS TO ITS APPLICATIONS IN REGENERATIVE BRAKING AND POWER GENERATION

A dynamo is a direct-current generator that converts mechanical energy—such as rotational energy—into electrical energy. While they were once used as charging devices in automobiles, the basic principles of power generation are also applied in modern motors and regenerative systems. A motor is typically a device that uses electricity to generate rotational force. However, when its shaft is rotated by an external force, it can function as a generator, making it useful for regenerative braking, energy recovery, and small-scale power generation. In this article, we’ll explain how dynamos work, how they differ from alternators, and their relationship to motors, and we’ll cover key considerations for motor selection suitable for power generation and regenerative applications.   Supervised by: C.I.

COMPARING SENSORLESS CONTROL AND MOTORS WITH ENCODERS | EXPLAINING THE DIFFERENCES AND HOW TO CHOOSE
COMPARING SENSORLESS CONTROL AND MOTORS WITH ENCODERS | EXPLAINING THE DIFFERENCES AND HOW TO CHOOSE

When selecting a motor control method for Brushless motors, some designers may wonder, “Which is more suitable: sensorless control or motors with encoders?” Since sensorless control eliminates the need for a position sensor, it is well-suited for miniaturization and cost reduction. However, position estimation can become difficult during low-speed operation or startup. Motors with encoders are well-suited for high-precision position and speed control, but it’s important to note that they tend to increase the number of components and cost. In this article, we will compare the mechanisms and differences between the two methods and explain how to select the control method best suited for your application from the perspectives of control accuracy, starting performance, reliability, and cost.   Supervised by:…
