A ROTOR POSITION DETECT STRUCTURE OF BRUSHLESS DIRECT CURRENT MOTOR

摘要

The present invention relates to a rotor position detection structure of a brushless DC motor, and has a simple structure as well as an increase in output compared to the same standard compared to the conventional structure.;This allows the permanent magnet to be in contact with one side of the rotor which is fixed to the shaft and at the same time to have a cylindrical shape with at least 4 pieces to be fixed to the shaft, and to fix the hall sensor to the inner side of the cover. When the permanent magnet rotates together, the hall sensor detects the magnetic field effect of the permanent magnet so that the controller can detect the position of the rotor.
