| Abstract: | A method of rotating sppeed measurement with high accuracy over a wide speed range and its relative circuits,by which the average measuring times can be automatically determined according to the on-line rotating speed,is presented in this papor.An oporation principle and method of extendible 16-bit digital/analogue converter which consists of two 8-bit digital/analogue convertero is also dis-cussed.COmbined with the two parts mentioned above,a spoed feedback unit,in which the rotating speed can be measured and analongue output value produced,is formed.The measurement range of the umt is from 0.03r/min to 65000r/min,and its accuracy within 0.1%. This unit can be convenientlyused in any high accurate speed control system which is extensively applied in the fields of industry con-trol ,energy saving control,etc. |
