ROTOR STRUCTURE OF A BRUSHLESS DIRECT-CURRENT MOTOR, CAPABLE OF IMPROVING THE PRODUCTIVITY BY SIMPLY COMBINING A PLURALITY OF MAGNETS

摘要

PURPOSE: The rotor structure of a brushless direct-current(BLDC) motor is provided to reduce cost required for manufacturing processes by accurately installing magnets to a rotor without jigs.;CONSTITUTION: A casing(20) is combined on the upper side of a base plate(10). The casing is fixed in a stator(30). The stator is composed of a base core(31) and a separate core(32). The separate core forms a magnetic pole by being combined with the outer peripheral part of the base core. A rotor surrounding the stator in the casing is installed to be rotatable. A rotary shaft(50) is combined with the rotor and passes through the casing.;COPYRIGHT KIPO 2011
