BLDC Motor

  • We have invented the first BLDC motor in the world with built-in driver that has a built-in cooling fan and a heat sink for heat reduction. The design breaks with traditional patterns, incorporating a simple design and providing more efficiency power.
  • The IEC series offers high interchangeability, and the PCB junction box can be attached on the outside for even more flexibility and customization options.
  • During operation, Yen Power BLDC motors allow for quick adjustment to always maintain the optimal processing speed according to the loading. This feature makes our products suitable for a wide range of customers including small volume processing and mass production orders.
  • Technology
    We have developed a new multi-functional driver that offers a wide range of functionalities as well as flexible settings. Besides, we also offer a wide range of optional accessories for our customers.
  • Applications
    We have developed a number of competitive products based on our excellent motor technology. Those products include servo chamfering machines, servo drilling and tapping machines, and DC inverter fans. We hope that in the future we can extend our activities as an OEM and ODM supplier for small-sized portable and desktop machines.
  • Yen Power designs every component with care and continues to make adjustments based on its profound experiences in the industry. All these efforts stem from Yen power's unshakeable perseverance since 1976.

  • A BLDC motor the same size as a conventional IEC motor. However, the driver is already built into the motor frame, saving you space on the outside.
  • Breaking with traditional patterns, the design is simple, yet beautiful, providing a built-in 'endless source' of servo motor power.
  • The intuitive controls make it easy for operators to put all of the motor's great features to use: low RPM, high torque, low heat generation and energy consumption, high efficiency, a space-saving design, easy assembly, and high flexibility.
  • Die-casting technology is used to manufacture the aluminum outer frame while the front and back are made via aluminum extrusion.
  • Our energy-efficient motors meet the most rigid standards and have received several certifications, such as CE, UL, CCC, and RoHS.
  • PCB Junction Box for external devices: Speed Control Output, Rotation Direction Output, Malfunction Indicator Lamp, Power Input Signal, RPM Signal, RPM Settings.
