External-rotor ECM NECE55 Series

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: Yes.

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

⚫ Fixing of the Motor: Fix the motor through the 3-M4 screw holes on the middle tube 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. It can also be used for other  applications with low power

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 6000RPM). 

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. 

Remarks: 

1) Only the dimensions marked in letters are changeable as needed. Other dimensions are fixed. 2) The height and the shape of the above motor body are not changeable unless we open new moulds.
