The approach based on linear Halldevice, without increase in the cost, simple installation and the results meet to the requirement.
该方法基于线性霍尔元件,基本上不增加控制系统成本,安装简便,效果良好。

Fireresistant Halldevice and SmCo rotor is used to design position and speed sensor, and the corresponding doubling circuit and decoding circuit is designed.
It can be seen from the formula: for a certain Halldevice, the magnetic field B0 can be indirectly measured through measuring the Halldevice if only the passing current I is constant.
