轉矩突降 的英文怎麼說
中文拼音 [zhuǎnjǔtūjiàng]
轉矩突降
英文
torque breakdown-
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。From the engineering practice of the optomechatronics design for fast, the working principle for system and hardware realization are described, and motor ascending and descending velocity arithmetic is discussed in this thesis, including the realization of the system control loop, the principle of servo control card and its hardware and software realization, the principle of moment real time detect equipment and its hardware and software realization
