  • The gold antenna array pops out, and sees all.

  • With the fan released, it looks to be powered by a Nidec brushless DC motor, model number AG720K01.

  • The motor controller IC is an Allegro Microsystems A5940LPT Three Phase Sensorless Sinusoidal Fan Driver.

  • We noticed a few cavities around the edges of the impeller filled with some sort of epoxy (on both sides). We suspect it's for fine-tuned balancing, to keep the fan running smooth and quiet.

取下金色的天线阵列，详情看这里.

取下风扇后，我们发现由尼得科无刷直流电动机（型号AG720K01）驱动。

电机控制器IC为Allegro Microsystems A5940LPT 三相无传感器正弦风扇驱动器。

我们注意到在叶轮边缘周围有一些空腔(两侧都)填满了某种环氧树脂。 我们怀疑这是为了进行微调的平衡，以使风扇运转平稳而安静。
