The invention discloses a motor stator for a pump valve. The motor stator at least comprises a housing, an integrally molded hollow ring-shaped iron core whose inner ring is provided with tooth portions, a circuit board, a fixed frame including a plurality of positioning grooves and limiting surfaces between adjacent positioning grooves, sheet-shaped multiple pole shoes whose lower surfaces fit arc-shaped cutting surfaces of the tooth portions, a bearing which has an arc surface that at least partially matches a rotor bearing sleeve, a bearing bracket, and a stator casing, wherein an outer edge is formed by an upper opening of the stator casing, an outer side wall fits upper surfaces of the pole shoes, a protrusion is formed in a center, and a flow guide surface that facilitates the flow of fluid is formed by an inner side wall of the stator housing. The invention also discloses an assembly method of the motor stator for the pump valve. The iron core and the pole shoes of the inventionare made by molding soft magnetic composite materials which are electrically insulated from each other, the iron loss is low, and products of different shapes can be designed, the iron core, the poleshoes and the stator casing have certain arc structures, the utilization rate of the space inside the motor stator is higher, and the whole installation is convenient.
Description
technical field [0001] The invention belongs to the technical field of pumps and valves, in particular to vane pumps, and in particular to a motor stator for pumps and valves and an assembly method thereof. Background technique [0002] Existing electrical and electronic stamping sheets are superimposed with the same silicon steel sheet, and the shape of each punching sheet is the same. The stamping dies corresponding to the steel sheets are different, the production cost is high, and the process control is difficult. [0003] For example, patent CN201420032873.6 discloses a silicon steel sheet for motors, which is provided with an integrally formed silicon steel sheet body, and a plurality of buckles are arranged on the inner or outer edge of the silicon steel sheet body; Extending in the circumferential direction, multiple buckles form a circle, which is detachable and convenient for winding. However, the iron core is still made of a series of identical silicon steel she...
