BRUSHLESS MOTOR FOR FLUID PUMP AND FLUID PUMP USING THE MOTOR

摘要

PURPOSE: A brushless motor for a fluid pump and a fluid pump using the same are provided to achieve an excellent operation characteristic by overcoming a durability problem due to a DC motor and the degradation problem of energy efficiency. CONSTITUTION: A brushless motor for a fluid pump comprises a stator core(5) which has a cross sectional structure including 6 slots(3) for a coil between core shoes(1) due to the six core shoes which are symmetrically projected to the center of a circle and a core shoe groove(7) which is formed in the inner side of each core shoes with being recessed along the longitudinal direction of the stator core. Two or more core shoe grooves are formed centering around the core shoe groove which is separated with a fixed angle about a straight line pass through the center of the core shoe.
