  1. Traditional direct torque control uses two value torque regulator which makes zero voltage vector work long and make flux shape bad seriously and makes response time long when the speed of induction motor is very low or drops down quickly. in order to solve this problem the thesis puts forward a new way to use three - value torque regulator, when the motor speed is very low or drops down quickly, the contrary voltage vector is used instead of zero voltage vector and the between the stator flux and rotor flux is reduced quickly so that torque is reduced quickly and response time becomes shorter

    為此,本論文提出三點式轉矩調節,這樣當電機低速運轉或給定轉速突降時,不是加零電壓矢量,而是加反方向的電壓矢量,使定子磁鏈與轉子磁鏈之間的夾角迅速減小,從而使電磁轉矩也迅速減小,大大減小了調速時間,同時磁鏈值仍然保持基本恆定,輸出比較穩定的電磁轉矩,這在電機制動過程中非常有用。
  2. By increasing the resistance, the characteristic will cut zero - speed axis to give a lower, though adequate starting torque and a reasonable starting current

    並勵電動機(機械特性)方程表明:若磁通和電壓恆定,則向下傾斜的轉矩/速度曲線的斜率是直接與電樞電阻成正比的。
  3. The rapid and reversible change between fluid and solid enables erf potential applications in mechatronic devices, cars and general machines. the transmission ability of a self - made cylinder coupling with zeolite - based erf was investigated, the torque transmission of the coupling in wide ranges of driving speed and electric field was measured. the relationship between the transmission torque, the zero field viscosity of erf and shear yield stress of erf under different electric fields was obtained and compared with theoretical prediction

    本文用沸石和硅油配製的電流變液,在自製圓筒式聯軸器上研究了在一定的速度范圍和有無電場作用條件下測量了其扭矩傳遞能力,獲得了傳遞扭矩與零電場電流變液粘度以及電場中電流變液的剪切屈服應力之間的關系,並與理論值進行了比較。
