中文拼音 [chǐcáokuāndù]
齒槽寬度
英文
space width-
The advantages of this modified technique can be stated as follows : ( 1 ) healing was apparently faster. ( 2 ) postoperative pain was minimal. ( 3 ) depth of vestibular fornix was increased markedly. ( 4 ) frenum and muscle attachment pull almost completely relieved. ( 5 ) there was less possibility of exposing a dehiscence or creating bone 1055 on adjacent teeth. ( 6 ) a function - ally adequate zone of attached gingiva was numerically increased
本改良法的優點，可歸納以下幾點: （ 1 ）手術傷口愈合快（ 2 ）術后疼痛小（ 3 ）口腔前庭寬度明顯增加（ 4 ）頰系常及肌肉的拉扯，幾乎獲得完全改善（ 5 ）不易引起手術區周圍齒槽骨的裂開缺損（ 6 ）固著性齒齦寬度的增加至為明顯。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。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。A permanent magnet synchronous motor is selected so that the system could work excellently. multiform measures are taken to weakening the torque ripple, such as adopting stator - flume, choosing right ratio of magnet - width and slot - width, and programming properly. a permanent magnet synchronous motor cad software is worked out for predigesting the design of the motor
力矩脈動是衡量交流伺服系統性能優劣的重要指標，為達到理想的控制效果，系統採用正弦波驅動的稀土永磁同步電動機作為執行元件，電機本體的設計綜合採用定子斜槽、將轉子永磁體連續移位、合理選擇永磁體寬度和齒槽寬度比等方法，基本消除了齒槽轉矩；對于紋波轉矩，系統採用軟體的方式加以削弱和補償。分享友人
