Success Story 3

Leveraging the Compact Size and High Power Density of BLDC Motors to Streamline Models and Reduce Inventory Pressure
2025/06/25

Demonstration

Traditional induction motors are bulky and energy-consuming, leading to diverse product models and high inventory pressure.
We assisted our customer in switching to brushless DC (BLDC) motors. By optimizing winding design, magnet grade, and the current-handling capacity of controller components, we achieved the following results:





Solution

  • Adopted BLDC motors with a standardized frame size to replace multiple induction motor models
  • One BLDC motor replaced two to three different frame sizes of induction motors
  • Greatly improved parts commonality, effectively reducing inventory and management pressure

Real-World Application: Ventilation Fans in the Planting Industry

  • Customer originally used 200W induction motors (1800 rpm)
  • After switching to BLDC, power consumption dropped to just 85W—more than 50% energy savings
  • Further optimization of winding and controller allowed the same BLDC motor to support both 200W and 400W models

Summary of Benefits: Clear, Data-Driven Results
