Brushless DC motor with outlaid hall element

The utility model relates to the improvement of the Hall element, etc. of a brushless direct current motor, comprising a motor shell body, and a stator and a rotor which are provided inside the motor shell body. The utility model is characterized in that: a circuit board is provided on the rear end part of the motor shell body; the circuit board and a control chip are suited and connected on a rear end cover by suited connection elements; the control chip is abutted on the rear end cover; a Hall element is provided on the circuit board; a magnetic steel which is induced with the Hall element is provided on the end of the rotor shaft of the rotor. Therefore, the utility model has the advantages as follows: reasonable design, simple structure, and marked effect; the Hall element is originally and externally provided, which overcomes the defect of layout on the original scheme, efficiently simplifies the structure of the utility model, and is convenient to assemble the Hall element; the performance of heat dispersion is markedly enhanced, and the working stability of a system is enhanced; the process of debugging is convenient and prompt, and is easy to be operated.
