電吹風無刷驅動方案：<\/strong><\/strong>
<\/span> <\/p>
<\/p> - 該方案針對電吹風開發(fā)的無霍爾控制， 通過單片機電勢<\/span>零采樣，軟件處理后，輸出方波PWM至IPM，從而驅動電機<\/span>工作，F逐步替代傳統(tǒng)電機。<\/span> <\/li> <\/ul>
<\/p> 方案特點：<\/strong><\/span> <\/p>
<\/p> - <\/span>無刷電機的電吹風電機用電子換向替代傳統(tǒng)換向，性能可靠<\/span>永不磨損，故障率低，<\/span> <\/li>
- <\/span>壽命比普通的風機提高10-30倍.<\/span> <\/li>
- <\/span>外置驅動的直流無刷屬靜態(tài)電機,空載電流小;<\/span> <\/li>
- <\/span>輸出功率高;<\/span> <\/li>
- <\/span>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> <\/li> <\/ul>
