Abstract:
PURPOSE: A hall sensor board for motor stator core sheet and a BLDC(Brushless DC) motor thereof are provided to fix the hall sensor board to the stator by covering the edge area of the hall sensor board. CONSTITUTION: A BLDC includes a stator(20), a rotor(10), a hall sensor board(30), hall sensor(40), and a case(50). The hall sensor board is directly fixed to the stator. The hall sensor is arranged to one side of the hall sensor board to sense leakage flux of the rotor. The hall sensor board is manufactured in a core sheet type.
