Invention Patented External-rotor ECM NECE52S 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 is a shaftless motor (Invention Patented) —- the motor has no rotor shaft so the  power cord can pass through the center of the motor from the rear end to the front  end. Then we can add the control PCB to the front panel of the fan. 

2. Invention Patent No.: 2019108692357. Utility Model Patent No.: 2019215506565. 

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

4. 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. 

5. It’s of long lifetime upto 50000 hours, wide range of applications & speed regulations. 

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

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

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.
