  • 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.

금색 안테나 배열이 튀어나와서 모든 것을 봅니다.

팬을 꺼내보면, 모델 번호가 AG720K01인 Nidec 브러시리스 DC 모터로 작동하는 것 같습니다.

모터 컨트롤러 칩셋은 Allegro Microsystems A5940LPT Three Phase Sensorless Sinusoidal Fan Driver입니다.

임펠러 가장자리 주변에 (http://d3nevzfk7ii3be.cloudfront.net/igi...) 일종의 에폭시로 채워진 구멍 몇 개를 발견했습니다. 이는 팬이 부드럽고 조용하게 작동하도록 미세 조정 균형을 맞추기 위한 것으로 보입니다.
