In the fieldweakening region, the torque capacity decreases with the increasing frequency, torque output capacity depends largely on the field-weakeningcontrol strategy.
在弱磁区，转矩能力随着频率的增加而减小，电机转矩输出能力很大程度上取决于弱磁控制策略。

Finally, the environment on crime prevention to crime field negates the formation of environmental crime is divided into time, space and crime control mechanisms weakening the three areas.
最后，从对犯罪环境的预防来阻却犯罪场的形成，犯罪环境分为时间、空间和犯罪控制机制弱化三个方面。

Proposed a vague location control method to launch the rotor, which is an effective solution to the problem of weakening magnetic field caused by traditional DC torque methods.
