置零脈沖
英文
quench pulse-
The microprocessor is used to realize digital control as flip plus of the scr. the ic chip sa866ae of mitel company is utilized as the low frequency signal generator of the system. furthermore in the zero - current detection circuit, use the photocoupler gaalas ired and photo ic to detect zero - current, furthest shorten the commutating " died region ", prevent the current from distorting
設計中採用單片機控制可控硅的觸發脈沖,實現數字化控制,並利用mitel公司的三相pwm交流電機脈寬調制晶元sa866ae ,成功研製了交-交頻器中的低頻信號發生器裝置,效果良好;此外利用用光電檢測元件進行系統零電流的檢測,盡可能地縮短換相死區,防止電流發生畸變,成功地解決了原有低頻電源系統中存在的兩大難題。In this paper, we design two types of flexible hinge, which are column stagger flexible hinge and flat straight round flexible hinge. the control system of the drive equipment includes the unity of the central console and control module. the console regards vc + + 6. 0 as the tool, it can set pulse number and pulse speed, start and stop the electromotor
微驅動裝置的控制部分由上位機和控制模塊組成,上位機採用vc + + 6 . 0編制控制界面,可以設置電機旋轉所需的脈沖數和脈沖速度,可以實現電機的起停,正反轉及脈沖清零等工作,還可以分別控制不同鏡架的電機及相同鏡架的兩個電機。
