摘要
The invention sikimyeo shorten the estimated short time to increase the initial angle estimation accuracy, the initial angle estimation period relates to a method for estimating the initial magnetic pole of the permanent magnet type synchronous motor , and also to reduce the motor noise reduced as well as the initial estimate for each movement of the rotor , is a half-sine test in the D -axis current in the positive and negative half additionally minimizing the movement distance by applying a sine wave , and the motor torque is proportional to the movement of the rotor (slider) for a constant current , and use the displacement of the movement instead of the torque value using the cosine values having a relationship with respect to the magnetic pole position of the torque estimate the magnetic pole position by finding the position at which the minimum and , for each of the initial estimate by applying a test current to the Q axis is characterized in that it determines the sign of the magnetic pole position .
