摘要
Abstract
An detection method of initial rotor position for the elevator of permanent magnet synchronous traction machine was proppsed. The approach improved the conventional fluctuating high-frequency voltage signal injection method in the arithmetic,the position of d-axis could be faster and more accurately calculated than the traditional method. When the fluctuating high-frequency voltage signal was injected into the stator windings,the rotor position could be gotten from the current response signal because the stator windings inductance varies with the rotor positionθ. The direction of rotor flux was achieved. Motor parameters and extra hardwares were not necessary in this method.the experimental results show the feasibility and effectiveness,especially in the low speed and zero-speed.关键词
