Technical Field
The utility model relates to a flat wire stator winding device suitable for oil field.
Background
The disk type permanent magnetic direct drive system directly drives the speed reducing mechanism for the oil pumping machine, and the special installation position and installation space determine that the oil pumping permanent magnetic motor in the oil field can only adopt a disk type structure, and has small axial length and larger diameter. At present, a stator winding of a permanent magnet motor for pumping oil in an oil field mostly adopts a multi-strand copper wire random-embedded or formed winding. The wire embedding of the random-embedded winding is complex, the embedding needs shaping and other processes, the end part of the winding is large, copper wire materials are wasted, and the occupied axial space is large; the coil is processed into a relatively fixed shape before the coil is inserted into the coil, shaping is not carried out after the coil is inserted into the iron core slot in principle, the slot fullness rate is low, and the forming is influenced by forming machinery, so that the coil is not suitable for mass production.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough in the current product, provide a flat wire stator winding device suitable for oil field.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides a flat wire stator winding device suitable for oil field, includes that a plurality of stator splits piece, flat copper wire, casing, single flat copper wire is around on the stator splits piece, splice into the stator circle each other between a plurality of stator splits piece, the stator circle is installed on the casing, the stator splits piece is equipped with the stator piece, the both ends of stator piece all overlap there is the insulator, the stator circle is circularly, a plurality of stator splits piece along the marginal evenly distributed of stator circle.
Preferably, the stator segments are provided with protrusions and grooves, and the plurality of stator segments are spliced into the stator ring through the protrusions and the grooves.
Preferably, the protrusions and the grooves are positioned on two sides of the stator piece.
Preferably, the insulator is located on the outside of the stator plate.
The utility model has the advantages as follows: the utility model discloses a flat wire stator winding is by the coiling of single flat copper wire, and the structure is inseparable, and production simple process, and shortened winding head length greatly, and save material is favorable to revising the winding number of turns simultaneously, and a plurality of stator splits the piece along the marginal evenly distributed of stator circle, therefore structural stability is high, and is durable.
