Fireresistant Hall device and SmCo rotor is used to design position and speed sensor, and the corresponding doubling circuit and decoding circuit is designed.
采用耐高温的锁定型霍尔元件和钐钴永磁转子分别构成位置与速度传感器，并设计相应的速度信号倍频电路与位置信号译码电路。
It can be seen from the formula: for a certain Hall device, the magnetic field B0 can be indirectly measured through measuring the Hall device if only the passing current I is constant.
从公式中可以看出，对于一定的霍尔器件，只要通过的电流i恒定不变，便可以通过霍尔器件的测量而间接测定磁场B0。
The mech electronic method is used when the tool turret is turned, the tool turret is positioned roughly by using Hall device in control circuit, and accurately by using a triple gear plate.
刀架转位分度采用机-电结合的方法，即先在控制电路中使用霍尔元件进行粗定位，再在机械上采用三齿盘实现精定位。
