KNOWLEDGE BASE --- Advantages of Inner Rotor BLDC Motors

In an inner rotor brushless motor, a rotor with permanent magnets rotates around an axis in a fixed stator with coils around it. Here are the main advantages of internal rotor brushless motors:

  1. The moment of inertia of the rotating shaft is small. 
  2. The heat dissipation performance is better. 
  3. Inner rotor BLDC motor provides ability to downsize the main unit.
  4. This brushless motor is particularly suitable for high-speed applications where low noise and reliable, long life operation are particularly important.
  5. Widely used in household industry, office automation, industrial control, ATM, energy industry, textile industry, automotive industry, logistics industry, medical industry, etc.
