Embodiment Construction
[0014] Such as Figure 1 to Figure 3 As shown, the motor of the present invention includes a support base 10, a stator structure 20 sleeved on the support base 10, and a rotor structure 60 that interacts with the stator structure 20 (see Figure 5 ), the rotor structure 60 surrounds the periphery of the stator structure 20.
[0015] The center of the support base 10 protrudes upward in the axial direction to form a hollow sleeve 12 for carrying bearings and the like to support the rotation of the rotor. The sleeve 12 protrudes outward on the outer wall surface of the top end to form a protrusion 14 for cooperating with the stator structure 20 in the circumferential direction, and the protrusion 14 is preferably strip-shaped. A fixing post 16 and a positioning post 18 are also formed on the support base 10. In this embodiment, there are two fixing posts 16 and two positioning posts 18, which are arranged around the sleeve 12, and the positioning posts 18 and the fixing posts 16 a...

A motor comprises a support base, a stator structure, and a rotor structure. The support base is provided with a hollow sleeve which supports rotation of the rotor structure. The stator structure comprises a magnetic core, a winding frame coating the magnetic core, and a coil wound on the magnetic core. The magnetic core comprises an annular yoke and a plurality of teeth extending outward along the radial direction from the yoke. The winding frame comprises an insulating part coating the magnetic core and a connecting part disposed inside the insulating part. The connecting part is composed of an annular substrate integrally extending inward along the radial direction from the insulating part, a cylinder integrally extending along the axial direction from the inner edge of the substrate, and a plurality of blades connected between the outer wall surface of the cylinder and the inner wall surface of the insulating part. The cylinder is sleeved in the sleeve of the support base. According to the winding frame of the stator structure of the motor, the cylinder is formed integrally inside the magnetic core and connected with the support base, so materials are saved, and the weight of the stator structure and the weight of the motor are reduced effectively.
Description
Technical field [0001] The invention relates to a motor, in particular to the stator structure of the motor. Background technique [0002] As a power source, motors are often used in daily production and life, such as electric fans, washing machines, and water pumps. Generally, a motor consists of two parts: a rotor and a stator. Wherein, the stator is composed of a magnetic core and a coil wound on the magnetic core. The rotor is provided with a permanent magnet. When the stator coil is energized, a changing magnetic field is generated, which acts with the magnetic field of the rotor to drive the rotor to rotate and drive the load. [0003] The magnetic core of the existing stator is usually made by stacking a large number of silicon steel sheets, and each silicon steel sheet is directly punched out of sheet-like raw materials, including a ring-shaped yoke and teeth radiating outward from the yoke. A mounting part is provided in the center of the yoke for fixing the stator to ot...
