换向装置 meaning in Chinese
commutating device
direction change device
reversing arrangement
reversing device
Examples
- The parallel robot has become a hot spot for a long time because of its simple structure , high stiffness , high precision , and low movement inertia . it especially adapted to the task , which required high precision , heavy load and limited space
并联机器人具有结构简单、刚度好、定位精度高、动态响应快等优良特性，特别适用于高精度、大载荷且工作空间较小的场合，在装配生产线、高精密机床、飞行模拟器、卫星天线换向装置等等很多方面都有着巨大的应用价值。 - The chip jk3ce that is one of micro - controllers in motorola 68hc08 family is used as control unit in this system . the zero crossing point of the back emf can be obtained by comparing the terminal voltage with the virtual neutral point , then using the software of the system can figure out the commutation period . the electronic commutation replaces the mechanical commutation in this way
本系统采用的控制芯片为motorola系列单片机中的jk3ce ，反电势过零点可以通过比较电机端电压和虚拟中点电压来得到，将过零点信号送往单片机捕捉端口后由系统软件来确定换相时刻，这样就可以由电子换向装置替代机械换相装置，有利于提高系统运行的可靠性，并降低了系统维护的费用。
