BLDC Ceiling Fan


BLDC (Brushless Direct Current Motor) is a remote-controlled, energy-efficient motor that offers high efficiency, improved control, enhanced performance, reliability, and longevity. The control algorithm used in the drive can vary depending on the application and may include techniques such as field-oriented control (FOC) for precise control and work for low voltages.


  • Controls the speed of the fan for optimized airflow and low noise
  • Included protection features to ensure safe and reliable operation of the fan
  • Field-oriented control based on single-shunt topology supports smooth fan motion
  • Stabilize operation by regulating voltage, even with fluctuations
  • Sensor-less devices estimate position using the motor back emf
  • A driver has addons features like IPD(Initial Position Detection), SIM(Start In Motion), braking, and field weakening


  • Electric vehicles
  • Industrial automation
  • Robotics
  • Home appliances
