外同步 meaning in English
external clocking
external synchronization
Examples
- In video recording , a state in which the playback system is in synchronism with the external synchronizing pulses
在录象技术中，放象系统与外同步脉冲处于同步的一种状态。 - It is analyzed in details the control of permanent magnet synchronous motor in the light of external synchronous control , self synchronous control and weak magnet control
摘要对永磁同步电动机的控制从外同步控制、自同步控制及弱磁控制等几方面进行了详细分析。 - The theoretic basis and the dat agram format of the newly propounded rts method are presented . finally , in the protocol stack of ip over ethernet , after the analysis of plesiochronization method and external clock method , a new synchronization method of absolute time stamp ( ats ) method is put forward , and detailed discussion is presented in this thesis
针对物理层不能提供同步的情况(如ipoverethernet ) ，本文在分析基于外部同步信息的准同步法和外同步法以及基于业务码流的自适应时钟法之后，提出了一种新的绝对时标法，并对该方法的实现进行了较为详细的研究。 - The mcu of system is the tms320f240 dsp chip produced by ti company . it can put out six ways pwm signal , with ( 10 bits ) a / d , detecting the signal of motor rotor position and phase compensating , the control of closed _ loop speed and stably switch form step _ off to step _ on of bldcm
系统中采用ti公司的tms320f240系列dsp芯片作为微处理器，可以方便的输出6路pwm信号、实现( 10位) a d转换、完成电机转子位置信号的检测与相位补偿、对系统进行速度闭环控制以及实现无位置传感器bldcm从外同步向内同步的平稳切换。 - It elaborates on the 3 - step start technique . i adopt the method which permits the bldc motor to automatically search the best time to change its operation stage from a separately controlled synchronous one to a self controlled one using the back emf as the commutation signal . this method prevents the stepping out and stopping problems in the changing procedure of the motor
阐述了电机的三段式起动方法，在直流无刷电机由起动阶段外同步运行切换到反电势换向自同步运行的过程中采用了自寻最优点切换的方法，保证了电机在切换过程中不会发生失步和停转现象。
