Document Type and Number:
Japanese Patent JP7480366
Kind Code:
B2
Abstract:
An electric pump (1000) comprises a stator assembly (2). The stator assembly (2) comprises a stator core (21) and a winding (22). The winding (22) comprises a main body section (221), a first section (222), and a second section (223). The main body section (221) is connected to the first section (222) and the second section (223). The stator core (21) comprises a core tooth portion (212), a core yoke portion (213), and a core neck portion (214). The core yoke portion (213) is located at an outer periphery of the winding (22). A first reference plane is defined, said first reference plane coinciding with a center axis line of the core tooth portion (212) in an axial direction thereof and a center axis line of the core neck portion (214) in an axial direction thereof. In a cross section of the stator assembly (2) along the first reference plane, an upper end of the main body section (221) is level with an upper end of a main body portion of the core yoke portion (213), and a lower end of the main body section (221) is level with a lower end of the main body portion of the core yoke portion (213). The electric pump (100) further comprises a shield member (5). The material of the shield member (5) is a conductive metal material. At least a portion of the shield member (5) is located at an outer periphery of at least one of the first section (222) or the second section (223). The invention reduces electromagnetic waves radiated outward, thereby reducing interference of the electric pump (100) with respect to the external environment.
