中文拼音 [màidòngqǐdòngjī]
脈動啟動機
英文
impulse starter-
Water feeding framework takes electromagnetism water valve as administration component and is added relief valve for stabilizing hydraulic pressure ; the system has large, middle and small water valve that changes unlock combination of electromagnetically operated valve, which can get seven different water flux ; if it is necessary, it should adopt microseism water feeding that can make water feeding get stepless timing
3加水機構加水機構採用電磁水閥作為執行元件，加入調壓閥穩定水壓，系統共設大中小三路加水閥，變化電磁閥的開啟組合，可以得出7種不同的加水流量，必要時採用脈動加水法，可使加水達到無級調速。Empty affect refers to the frequency at empty electrical motors from lock - in normal circumstances to activate the pulse frequency
空載牽入頻率是指步進電機在空載情況下能夠從鎖定狀態正常啟動的脈沖頻率。Secondly, the power density spectrum is calculated from fft and the units " behavior is analyzed in the frequency domain ; the waterfall form for the start up process is plotted
運用fft求取功率譜，分析信號的頻域特性，繪制啟動過程瀑布圖;分析尾水管壓力脈動對機組軸系的激勵作用2, the single - phase electrical strict sense, the main winding of the magnetic field is generated directly to the pulse magnetic field rather than straight to rotary magnetic field is not a moment ; namely : supply of electrical equipment not own
2嚴格意義上的單相電機，其主繞組所產生的磁場是直來直去的脈動磁場而非旋轉磁場，是沒有啟動力矩的即：通電后電機不會自己轉動。In teletypewriter applications, the uniform shifting of the beginning of all marking pulses from their proper positions in relation to the beginning of the start pulse
在電傳打字機應用中，所有標記脈沖首部從它們的正常位置相對于啟動脈沖首部的均勻位移。The system had auto startup and stop function by software. the dsp based motor control system had lower current harmonic, more efficient use of supply voltage than spwm, less switch loss. on the other hand, this system make a lower noise for the pwm modulation. frequency is up to 20khz
本系統實現了電機的軟啟動、軟關斷功能，電機電流的諧波失真較少，電壓利用率比常規的正弦波脈沖寬度調制（ spwm ）有了較大的提高，器件的開關損耗也得到了明顯的減少。分享友人
