| Abstract: | A simple but effective method to observe PMSM rotor position is presented in this paper.A high frequency voltage is injected into the motor and it will cause a little change of current signal because of the anisotropy of the machine.By processing the current in the armature,this method can calculate the rotor position accurately.This paper also presents a new way to observe the original rotor position when PMSM is standstill.The results of simulation show that this method can work feasibly and effectively. |
