The "Long-Life Fan Series" is a product suitable for maintenance-free operation of devices and for equipment that operates 24 hours a day (such as power supply, environmental energy, automotive, and elevator fields). By using double-shielded ball bearings filled with grease that has a low temperature coefficient, we have suppressed the reduction of grease due to fan operation over a wide temperature range. The adoption of ball bearings with a structure exclusive to this series has achieved smooth rotation without play. We have repeated temperature acceleration life tests to enhance reliability. 【Features】 ■ Continuous operation possible for 100,000 hours (at 60°C) ■ Improved rotor balance and air delivery efficiency per rotation with newly designed blades ■ Reduced temperature rise of bearings ■ Reduced load on bearings through research on the optimal retention force *For more details, please refer to the PDF document or feel free to contact us.

The "J Series" is a product designed for long life specifications of 100,000 hours at 60°C, and is equipped with a standard high-temperature specification of 85°C for use in high-temperature environments. By effectively utilizing the magnetic flux of the magnet, it generates a large rotational force with a small amount of power, resulting in energy-saving effects. With the soft start function and power limiter function, the current during automatic recovery operation when locked is controlled to be below a certain value, making it possible to suppress the temperature rise of the coil. This product solves the heat problems associated with the miniaturization and high density of your products. 【Features】 ■ Reduces unnecessary power that does not contribute to rotational force ■ Smaller coil heating allows for driving with larger currents ■ Uses low-noise special shape bearings ■ Limits large currents at startup to reduce power consumption ■ Designed with a dedicated speed to suppress noise *For more details, please refer to the PDF materials or feel free to contact us.

The "YP-DFC01Z" is a DC fan controller that allows for stepless control of the rotation of DC fans (rated at 12V) from 0 to 100%. Thanks to its internal PWM control method, it generates less heat compared to variable resistor methods, while achieving stable rotation. It has a simple design that reduces its size. At startup, it provides a momentary surge of 10.5V (for 1-2 seconds), eliminating startup failures due to insufficient startup voltage. Additionally, for fans with sensors, it outputs the sensor signal directly to the outside of the circuit board. 【Features】 ■ Compatible with small to medium fans, up to a rated current of 3.0A ■ Allows for stepless control of the rotation of DC fans (rated at 12V) from 0 to 100% ■ Generates less heat compared to variable resistor methods ■ Compact size with a simple design ■ Provides a momentary surge of 10.5V at startup *For more details, please refer to the PDF document or feel free to contact us.

1. What is the lifespan of a fan motor? Generally, the lifespan of a fan is referred to as "expected lifespan," which is represented by the "calculated value of bearing lifespan." This is mainly because the lifespan due to the lubrication (bearing grease) in the bearing section usually comes before the mechanical lifespan. Long-life type fans incorporate various innovations to extend this lifespan. Abnormalities in fan motors include reduced rotation, complete stop, increased current, and abnormal noise, among others. Various functions are built into fan motors to prevent or monitor these abnormalities. 2. What is a Brushless DC (BLDC) motor? Conventional motors cannot directly convert input to output. In this regard, compared to regular motors, BLDC motors have lower losses, allowing for high output and stability while being compact. They also have advantages over brushed motors: - Less mechanical lifespan - No electrical noise generated from commutators, etc. - No noise from brush friction Due to their structure, they detect the rotor position (and perform appropriate energization) to rotate the motor, enabling control of rotation speed, direction, and position without the need for special sensors.

1. What about processing related to fan motors and motors? Our company responds to various requests, such as terminal harness processing for motor and fan motor lead wires, and fan units that incorporate fan motors into chassis. 2. What is the difference between metal and resin blades in axial fan motors? Metal blades have better heat dissipation due to thermal conduction and can minimize the thermal degradation of ball bearing grease. Compared to resin, they have higher mechanical strength and are more resistant to aging and distortion. Furthermore, for detecting abnormal rotation of the fan in AC axial fan motors, the method of detecting the rotation of the metal blades and sending a signal is considered the most reliable. 3. Why do fan motor prices vary? Currently, fans ranging from a hundred yen to several thousand yen are circulating in the market. For consumer electronics, most fans are low-cost products produced overseas, supplied from factories that mass-produce the same models. While these fans are inexpensive, many of them raise questions about reliability.
