BLDC Motor Spec Table
This specification follows JIS (Japanese Industrial Standards). JIS is highly compatible with Korean KS standards and is essential when sourcing or maintaining Japanese-manufactured parts and equipment.
A brushless DC motor with long life and high efficiency, used in drones, power tools, EVs, and medical devices.
Practical Notes
- Dedicated driver (ESC or FOC controller) is mandatory. Direct power connection without a driver won't work.
- Sensorless mode is unstable at very low speeds. Choose hall-sensor-equipped type for precise low-speed control.
Selection Guide
Brushless design for long life and low electrical noise. Over 90% efficiency enables compact, lightweight design. Used in robot joints, drones, power tools, and medical devices. Requires dedicated driver (ESC/FOC controller).

FAQ
Difference between BLDC motor and AC servo?
BLDC uses trapezoidal commutation — simpler and cheaper. AC servo uses sinusoidal (FOC) drive for superior precision and response. Precision→servo; general drive→BLDC.
