摘要

PURPOSE: A brushless dc motor and a drain pump having the same are provided to reduce the friction loss of a rotary shaft while having high sealing. CONSTITUTION: In a brushless dc motor and a drain pump having the same, a housing comprises a rotor accommodating groove A stator is inserted into the outer circumference of the rotor accommodating groove and is fixed inside the housing. A rotor is inserted into the rotor accommodating groove, and it is installed in the outside of the housing to be rotatable. A sealer is included in the outside of the rotor and opens the rotor accommodating groove. The rotor comprises the rotary shaft The sealer comprises a lubrication storage(1422).
