PURPOSE: A BLDC(Brushless Direct Current Motor) blower motor for a hydrogen fueled car is provided to divide a mechanism for pumping hydrogen and a mechanism for driving a motor into separate spaces, thereby maximizing sealing effect. CONSTITUTION: A case housing(3) is assembled in the upper part of an impeller housing(2). The case housing is fixed by bolts(4). In the central inside of the case housing, a rotor core assembly(8) installed at a shaft(7) is installed by upper and lower bearings(9,10). In the lower end of the shaft, an impeller(11) is fixed. A stator core assembly(12) is installed in the outside of the rotor core assembly of the case housing. The upper part of the shaft is supported by the O-ring type bearing. A mounting portion formed by grooving is formed in the lower part of the case housing. |
