What is a brushless cooling fan motor

This new type of brushless motor is called an electronically commutated DC motor, which overcomes the defects of the first generation of brushless motors.

What is a brushless motor and its characteristics

Characteristics of brushless motor

1. Can replace DC motor speed regulation, frequency converter + frequency conversion motor speed regulation, asynchronous motor + speed reducer speed regulation;
2. It has the advantages of the traditional DC motor, and at the same time, the carbon brush and slip ring structure are eliminated;
3. With brake and dual steering functions;
4. Small size, light weight and large output;
5. Excellent torque characteristics, good torque performance at medium and low speeds, large starting torque and small starting current;
6. Stepless speed regulation, wide speed regulation range, strong overload capacity;
7. Soft start and soft stop, good braking characteristics, can save the original mechanical brake or electromagnetic brake device;
8. High efficiency, the motor itself has no excitation loss and carbon brush loss, eliminating multi-stage deceleration loss, and the comprehensive power saving rate can reach 20% ~ 60%.
9. High reliability, good stability, strong adaptability, simple repair and maintenance;
10. Resistant to bumpy vibration, low noise, small vibration, smooth operation and long life;
11. No sparks, especially suitable for explosive places, with explosion-proof type;
12. Trapezoidal wave magnetic field motor and sine wave magnetic field motor can be selected as required.
