Abstract

Sources of error are took into account while applying high frequency rotation voltage injection method to interior permanent magnet synchronous motor (IPMSM). A new method using the phase difference of two new tracking differentiator (NTD) output signals for solving the initial position of the rotor poles on the basis of the derivation of high frequency positive, negative sequence current is proposed. Method only need four parameters bus voltage, electrical angle of high-frequency signal and the inductance of direct and quadric axis, without using PI regulator or Luneburg observer. The experimental results verify the accuracy of the detection. The method can be used to solve the starting problem of the IPMS
