Brief Introduction : 

1. This ECM (Electronically Commutated Motor) is a high efficiency programmable  brushless DC motor utilizing a permanent magnet rotor and a built-in inverter. 

2. DC motor is significantly more energy efficient than AC motor and much easier  to control. The energy saving is upto 65% in average compared to shaded pole  motor, or 35% compared to PSC motor. 

3. The motor is of long lifetime, wide range of applications and speed regulations. 

4. It’s generally available for products of low speed (generally less than 6000 RPM). 

5. It’s with large rotation inertia, simple structure & not accurate starting position. 

6. The standard shaft diameter (d) is Ø8mm. It can be other diameters, with D-cut,  threads, etc., and the length (L) can be any as needed.


Main Characteristics : 

⚫ Motor Type: 3 Phase external rotor brushless motor. 

⚫ Control Driver Circuit: built-in circuit, sine wave drive (with lower noise and vibration, but the motor efficiency is also lower). 

⚫ Hall Sensor: No. 

⚫ Motor Rotation: can be either in CW or CCW direction as needed. 

⚫ Fixing of the Motor: By the 4 screw holes in the front metal cover of the motor (see from the below drawing).


Typical Applications : 

This motor is mostly used for fans (solar powered fan, table fan, desk fan, box fan, etc.), ventilators, etc.
