Problems solved by technology
Due to the high injection pressure during the injection molding process, there is a certain impact on the circuit board 1b', and the temperature of the mold and injection plastic may cause damage to the electronic components on the circuit board 1b', which may cause the circuit board 1b' to fail, thereby reducing The pass rate or life of the motor
In actual use, the circuit board 1b' is easily affected by the temperature rise of the winding 1a' and the temperature of the fluid, resulting in a decrease in the performance of electronic components and shortening the life of the motor

The invention provides a motor stator, a motor, a pumping device and a forming method of the motor stator. The motor stator comprises a winding assembly and a circuit board assembly, wherein the winding assembly comprises a winding, an electric connection part and a winding sealing part; the winding sealing part is arranged on the periphery of the winding; the electric connection part comprises a winding connection end and a circuit board connection end; the winding connection end is electrically connected with the winding; the circuit board assembly is arranged at an axial first end of the winding assembly; the circuit board assembly comprises a circuit board and a circuit board sealing part; the circuit board sealing part is arranged on the periphery of the circuit board; a circuit board connection end of the electric connection part is electrically connected with the circuit board; and the circuit board sealing part and the winding sealing part are respectively formed. According to the motor stator, the effects on the circuit board caused by pressure and temperature in a winding sealing part forming process can be avoided, so that the damages, which can be caused by the temperature of a mold and an injection molding material, to electronic elements on the circuit board can be relieved; the risk of a circuit board failure is reduced; the qualified rate of the motor is improved; and the service lifetime of the motor is prolonged.
Description
technical field [0001] The invention relates to the field of mechanical equipment, and more specifically, to a motor stator, a motor, a pumping device and a method for forming the motor stator. Background technique [0002] In the prior art, there are many types of structures of the motor and its stator. figure 1 It is a structural schematic diagram of the first motor and its stator in the prior art. Such as figure 1 As shown, in the motor stator of the first motor, the winding 10 and the circuit board 12 are welded and fixed, and then put into the isolation cover 13 . [0003] In the first type of motor, the stator of the motor uses an isolation cover 13 to protect the winding 10 and the circuit board 12 . Because the circuit board 12 is exposed to the air, it is easy to produce defects such as rusting of solder joints, poor heat dissipation, aging components, low protection level, and easy generation of water vapor due to temperature changes, so the safety of the circui...
