Embodiment Construction

[0034] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0035] The invention provides a submersible motor stator with outer slots and a manufacturing method thereof, see figure 2 The stator includes a stator core 2 and a plurality of stator slots 3 arranged in the stator core 2 and distributed around the center line of the stator core 2. The outer wall of the stator core 2 is also provided with multiple slots around its circumference. The outer slots 5 along the longitudinal direction of the stator core 2; each outer slot 5 corresponds to a stator slot 3 and communicates with the stator slot 3; the stator slot 3 is embedded with a stator coil, and the outer slot 5 Filled with magnetic epoxy for curing and sealing the outer slot 5 .

[0036] Further, the stator coil is fixed i...

Abstract

The invention discloses an oil-submersible motor stator with external open grooves and a manufacturing method of the oil-submersible motor stator. The stator comprises a stator iron core (2) and multiple stator grooves (3) which are formed in the stator iron core (2) and distributed around the center line of the stator iron core (2), and multiple external open grooves (5) which are formed in the longitudinal direction of the stator iron core (2) are formed in the outer side wall of the stator iron core (2) around the circumferential direction of the stator iron core (2); each external open groove (5) corresponds to one stator groove (3) and is communicated with the corresponding stator groove (3); a stator coil is embedded into each stator groove (3), and the external open grooves (5) are filled with magnetic epoxy resin used for curing and sealing the external open grooves (5). The oil-submersible motor stator can effectively shorten the coil inserting working time, reduce the coil inserting technology difficulty and increase the stator groove full rate, and then the purpose of improving the motor performance is achieved.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a stator of a submersible motor provided with outer slots and a manufacturing method thereof. Background technique [0002] The submersible motor is the power machine of the submersible electric pump, which drives the submersible centrifugal pump to absorb underground well fluid. The submersible motor belongs to the AC asynchronous motor, and its structure is basically the same as that of the ordinary asynchronous motor. However, in order to adapt to the special use environment of the submersible electric pump, it also has a special structure, which is mainly composed of a slender fixed part (stator) and a rotating part ( Rotor), the whole shape is like a slender steel pipe. In order to reduce the reluctance of the main magnetic circuit and reduce the excitation current, the stator core of the current submersible motor generally adopts a closed slot design, but the disadvantage...
