風扇無刷驅動方案：<\/strong><\/span><\/span>
正弦有霍爾<\/strong><\/span><\/span>
<\/span><\/strong><\/p>此方案使用有傳感正弦電流的方式驅動BLDC電機具有噪音小,成本低的特點,廣泛的應用于風扇,空氣凈化器等風機類產(chǎn)品。<\/span><\/span><\/strong><\/strong><\/p><\/span><\/span><\/strong><\/p><\/strong><\/p>
<\/span><\/span><\/strong><\/strong><\/p>方案特點：<\/span><\/span><\/strong><\/p>1、無刷電機的風扇電機用電子換向替代傳統(tǒng)換向，性能可靠<\/span><\/span><\/strong>永不磨 損，故障率低，<\/span><\/span><\/strong>壽命比普通的風機提高10-30倍;<\/span><\/span><\/strong><\/p>2、外置驅動的直流無刷屬靜態(tài)電機,空載電流小;<\/span><\/span><\/strong><\/div>3、輸出功率高;<\/span><\/span><\/strong><\/div>4、外置驅動的無刷電機可以做到體積很小,更方便整體設計.<\/span><\/span><\/strong><\/div>
