摘要
The present invention does not use a sensorless hall Hall sensors (Hall sensor) Linear Permanent Magnet Synchronous Motor and relates to an apparatus and method for controlling them. Hall sensor-less linear permanent magnet type synchronous motor with a permanent magnet unit, a guide (guide) means, and moving means, and a position detecting means. Electric motor control device comprising: means for generating a fourth body baesinho, and means for calculating the initial electrical angle of the moving means, the motor of the initial means for generating a new electrical angle of the moving means after the start, the new electrical angle means for generating an electrical angle is corrected by the correction and, applying a current corresponding to the corrected electrical angle, and the moving means comprises a main control (main control) unit for controlling the operation of the electric motor. And the motor control method comprising: applying a predetermined current to the moving means, the method comprising: calculating the initial electrical angle of the motor, a current corresponding to the electrical angle and the initial step of applying to the mobile unit, generating a fourth body baesinho and, generating a direction signal, on the basis of the body 4 baesinho and direction signal and generating a new electric angle, and a step for correcting the new electrical angle, a current corresponding to the corrected electrical angle in the moving means includes the step of applying.
