INNER TYPE BLDC MOTER

摘要

PURPOSE: A built-in BLDC(Brushless Direct Current) motor is provided to minimize vibration transferred to a motor housing by arranging an elastic member which pre-loads a bearing on a first bearing placed in a direction which mutually faces a hall sensor. CONSTITUTION: Top and lower motor cases(100,110) are interconnected and form a receiving space. A motor housing(120) is combined with the lower motor case. First and second ball bearings(200,210) are arranged to mutually face on the top and lower motor cases. A rotor(310) is combined with a rotary shaft(300) and integrally revolves with the rotary shaft. A hall sensor(400) is placed in the lower motor case and detects the position of the rotor.
