梯形齒 的英文怎麼說
中文拼音 [tīxíngchǐ]
梯形齒
英文
stepped tooth-
For the bldcm which has a general crest width of the back - emf waveform, two kinds of torque ripple conditions when drived by sine - wave current as well as by square - wave current are deduced based on the mathematical models. in addition, a comparison is carried out between these two conditions, which indicates that sinusoidal current driving is more favorable to minimizing the torque ripple when the crest width of the back - emf waveform is less than a certain value
闡述了抑制齒槽轉矩措施對反電動勢波形的影響，利用無刷直流電機的數學模型推導並比較了任意平頂寬度梯形波反電動勢在正弦波和矩形波兩種電流驅動下的電磁轉矩脈動情況，得出在梯形波平頂寬度減小到一定數值后採用正弦電流驅動更有利於減小電磁轉矩脈動。In chapter 5, using coordinate graphs, the influences of rectangular screw, trapezoidal screw and serrate screw on the generated axial thrust force, minimal mucus film thickness, load capacity of hydrodynamic pressure and circumferential friction are compared and analyzed
第五章，通過坐標圖對比分析了微型機器人在矩形螺紋、梯形螺紋、鋸齒形螺紋下，各螺紋參數對軸向摩擦牽引力、最小粘液膜厚度、粘液膜承載能力、周向摩擦阻力的影響。The non - ideal bemf waveform of bldcm is often caused by two facts. one is that the platform width of bemf waveform is less than 120 ; the other is the cogging harmonics existed in the bemf waveform
非理想反電動勢波形的無刷直流電機有兩種情況，一種是反電動勢的梯形波的平頂寬度小於120 ；一種是由於磁場分佈受齒槽的影響，反電動勢存在齒諧波，使其波形發生畸變。The motion of the two rotors with single - threaded, equal pitch trapezoidal profile was theoretically analyzed to eliminate the tooth interference
