Abstract
The utility model provides an insulating structure who makes up stator together piece, includes that the several pieces together the circular ring form stator that piece stator unit concatenates each other and forms, pieces together the stator unit and comprises "worker" style of calligraphy iron core, insulating gum cover, coil, and insulating gum cover surrounds I shape iron core "waist" portion, and the coil winding is sheathe in at insulating gum, its characterized in that: and an insulating partition plate is arranged between the adjacent split stator units. Compared with the prior art, the utility model, have and avoid piecing together looks or turn-to-turn short circuit between the block stator unit, simple structure, advantage with low costs.
Description
Technical Field
The utility model relates to a motor technology.
Background
The split combined stator has been applied to a certain extent in the field of large motors due to the advantages of high material utilization rate, high slot filling rate, almost no process limitation on the size of a slot and the like, but in the application process, the slot filling rate is generally designed to be higher, and the coils of adjacent split stator units are frequently touched, so that the condition of phase or turn-to-turn short circuit is caused.
Disclosure of Invention
The utility model aims at providing a can avoid looks or interturn short circuit, simple structure, the insulating structure of piece combination stator is pieced together to with low costs.
The utility model discloses a realize like this: piece the circular ring form stator that stator unit concatenates each other and form including the several, piece the stator unit and constitute by "worker" style of calligraphy iron core, insulating gum cover, coil, insulating gum cover around I shape iron core "waist" portion, the coil winding is sheathe in insulating gum, its characterized in that: and an insulating partition plate is arranged between the adjacent split stator units.
In order to further increase the insulation effect and avoid the contact of the enameled wire and the iron core, a gap is arranged between the insulating rubber sleeves at the joint of the two adjacent split stator units, and the insulating partition plate is arranged in the gap to separate the whole insulating rubber sleeves of the two adjacent split stator units.
In order to ensure the accurate positioning of the insulating partition plates, chamfers are arranged on the connected edges of the I-shaped iron cores of the two adjacent split stator units, the connected edges of the I-shaped iron cores of the two adjacent split stator units are combined to form a groove, and the bottom edges of the insulating partition plates are embedded into the groove.
Compared with the prior art, the utility model, owing to adopt insulating barrier to separate the coil on the adjacent two piece stator units of piecing together, consequently, have and avoid piecing together between the stator unit looks or turn-to-turn short circuit, simple structure, advantage with low costs.

Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings and examples:
as shown in fig. 1 and 2, the utility model discloses a ring form stator that stator unit 1 concatenates each other and forms is pieced together to the several, pieces together stator unit 1 and comprises "worker" style of calligraphy iron core 101, insulating gum cover 102, coil 103, and insulating gum cover 102 surrounds I-shaped iron core 101 "waist" portion, and coil 103 twines on insulating gum cover 102, its characterized in that: between adjacent split stator units 1, an insulating spacer 2 is provided.
The outer side surface of the insulating rubber sleeve 102 is an annular groove 1021, and the coil 103 is wound in the annular groove 1021 of the insulating rubber sleeve 102.
Further, a gap 3 is provided between the insulation rubber sleeves 102 at the junction of the two adjacent split stator units 1, and the insulation spacer 2 is provided in the gap 3 to completely separate the entire insulation rubber sleeves 102 of the two adjacent split stator units 1.
Furthermore, the connected edges 1011 of the I-shaped iron cores 101 of the two adjacent split stator units 1 are provided with chamfers 1012, the chamfers 1012 arranged on the connected edges 1011 of the I-shaped iron cores of the two adjacent split stator units 1 are combined to form a groove 4, and the bottom edge of the insulating partition plate 2 is embedded into the groove 4.
Further, as shown in fig. 3, the insulating rubber sleeve 102 with the annular groove 1021 and the i-shaped iron core 101 are integrally formed by injection molding; alternatively, as shown in fig. 4, the insulating rubber sleeve 102 with the annular groove 1021 is formed by butting a pair of U-shaped insulating rubber sleeves 1022 respectively clamped at the waist portion of the i-shaped iron core 101.
The insulating separator 2 is made of insulating paper.
