Problems solved by technology
When the motor stator is installed into the water pump body in a sub-package structure, if the motor stator shakes during the operation of the electric water pump, it will affect the stable operation of the rotor and cause the electric water pump to fail to supply water normally; therefore, in the structural design, it must be ensured that the motor stator is completely Constrained, fixed and reliable

The invention provides a separate structure of a motor stator of an electric water pump. The separate structure comprises a water pump body, the motor stator, a control board, a water pump rear end cover, an impeller cavity, a motor rotor, an impeller and a water pump front end cover, wherein a fine tuning part sleeves the tail end of the motor stator; the motor stator passes through the fine tuning part and no gap is generated between the motor stator and the inner diameter of the water pump body; the structure of the fine tuning part comprises a connecting base which can be fixed on the tail end surface of the motor stator; a plurality of connecting arms are uniformly distributed in the circumferential direction of the connecting base at intervals; the outer end of each connecting arm extends towards the front end direction of the motor stator in a bending manner and then forms a spring sheet; and a gap is arranged between the inner arc surface of the spring sheet and the outer peripheral surface of the motor stator. The target of designing the structure of the spring sheet is to ensure that the motor stator can be easily shifted into the water pump body through manpower when the motor stator is assembled in a non-interference fit manner; and meanwhile, no gap between the motor stator and the inner diameter of the water pump body is ensured, so that the radial direction of the motor stator does not shake when the water pump works.
Description
technical field [0001] The invention belongs to the technical field of electric water pumps for automobiles, and in particular relates to a motor stator subassembly structure of an electric water pump. Background technique [0002] The brushless DC motor is the driving part of the electric water pump. The stator of the motor is fixed, and the rotor of the motor rotates with the impeller. When the motor stator is installed into the water pump body in a sub-package structure, if the motor stator shakes during the operation of the electric water pump, it will affect the stable operation of the rotor and cause the electric water pump to fail to supply water normally; therefore, in the structural design, it must be ensured that the motor stator is completely Constrained, fixed and reliable. Contents of the invention [0003] The invention provides a motor stator subpackage structure of an electric water pump. The motor stator is loaded into the water pump body by adopting the ...
