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

THE ROLE AND SELECTION OF CARBON BRUSHES FOR MOTORS | EXPLAINING LIFESPAN AND REPLACEMENT TIMING
THE ROLE AND SELECTION OF CARBON BRUSHES FOR MOTORS | EXPLAINING LIFESPAN AND REPLACEMENT TIMING

Motor carbon brushes are components that transmit electric current through sliding contact with the commutator (or slip ring); in DC motors, they work in conjunction with the commutator to maintain rotation. They are used in a wide range of equipment, from industrial motors to power tools. If carbon brushes wear out or commutation becomes unstable, it can lead to sparking or damage to the commutator, making them critical from the perspective of maintenance and downtime risks. Carbon brush materials include electrographite, natural graphite, and metal graphite, among others, and selecting the appropriate material based on the application and operating conditions is essential. Understanding how to assess lifespan and replacement timing based on brush wear, as well as how to diagnose…

THREE CAUSES OF TORQUE RIPPLE AND HOW TO REDUCE IT
THREE CAUSES OF TORQUE RIPPLE AND HOW TO REDUCE IT

While a motor is rotating, the torque it outputs is not entirely constant. Instantaneous torque undergoes slight periodic fluctuations, manifesting as variations in rotational force. These periodic torque fluctuations are known as “torque ripple.” Significant torque ripple adversely affects equipment performance, leading to vibration, noise, reduced positioning accuracy, and degraded controllability.This is a technical challenge that cannot be ignored, particularly in fields where smooth operation and precision are directly linked to quality, such as medical equipment, optical equipment, and industrial robots. In this article, after clarifying the basic meaning of torque ripple and its difference from cogging torque, we will explain the main causes of its occurrence and methods for reducing it from the perspectives of design, control, and motor…

METHODS FOR CALCULATING MOTOR ROTATIONAL SPEED AND MOTOR CONTROL TECHNOLOGIES
METHODS FOR CALCULATING MOTOR ROTATIONAL SPEED AND MOTOR CONTROL TECHNOLOGIES

The ability to accurately measure and control a motor’s rotational speed is critical, as it directly impacts equipment performance and stable operation (required specifications). “I want to know the formula for calculating rotational speed.” “I want to understand how voltage and torque affect rotational speed” “I want to explore methods for achieving precise speed control” To address these technical challenges, this article provides a technically grounded explanation—ranging from the basic calculation formula for DC motor rotational speed to the factors affecting rotational speed, how to interpret T-N characteristics (torque characteristics) and how to use PWM control and feedback control for practical speed control. We provide information that will be useful to engineers in fields where reducing speed fluctuations and maintaining…
