Title:
STATOR ASSEMBLY FOR MAGNETIC LEVITATION MOTOR, MAGNETIC LEVITATION MOTOR, AND IN VITRO CENTRIFUGAL MAGNETIC LEVITATION BLOOD PUMP
Document Type and Number:
WIPO Patent Application WO/2023/179187
Kind Code:
A1
Abstract:
A stator assembly for a magnetic levitation motor (100), the magnetic levitation motor (100), and an in vitro centrifugal magnetic levitation blood pump comprising the magnetic levitation motor (100). The stator assembly comprises an insulating framework (1) wound with a coil (212) and a stator (20). The stator (20) comprises a stator yoke (21) in an annular configuration and at least one pair of stator teeth (211) provided on the stator yoke (21), a pair of the stator teeth (211) being arranged facing each other on the stator yoke (21). The stator teeth (211) each comprise a horizontal portion (31) and a vertical portion (32) that are perpendicular to each other, the lower end of the vertical portion (32) being loaded on the upper surface of the stator yoke (21). The insulating framework (1) is sleeved outside the vertical portion (32), and the vertical portion (32) has a first main side surface (321) and a second main side surface (322) radially opposite to each other, the first main side surface (321) being closer to the rotor (22) relative to the second main side surface (322). The first main side surface (321) is a plane or a cambered surface with a smaller curvature relative to the second main side surface (322), and the horizontal portion (31) protrudes radially from the first main side surface (321).
