Problems solved by technology

[0002] The coil of the existing cylindrical submersible linear motor adopts a circular cross-section electromagnetic wire, which is wound in one direction, and the lead wires come from the inner and outer sides. It must straddle the winding, so it is required to increase the insulation structure, which will occupy the volume and affect the cross-sectional area of ​​the wire in the limited space. Due to the small space in the oil well casing, it cannot achieve high power lifting

Embodiment Construction

[0012] See Fig. 1, 2, the concrete structure of the stator winding provided by the present invention is as follows (this example is wherein a phase winding in the three-phase winding): the magnet wire that the stator coil winding adopts is a flat magnet wire. The entire coil winding is provided with a plurality of single-cake coils 1, and the lead-out lines at both ends of each single-cake coil 1 are arranged outside the circle, and the lead-out lines of each single-cake coil 1 are connected in series (that is, the connecting wires between the single-cake coils 4). Each single-cake coil 1 has a double-layer structure, one layer of coil 2 is a clockwise winding structure, and the other layer of coil 3 is a counterclockwise winding structure. The clockwise winding direction of one layer of coil 2 is converted to the counterclockwise winding direction of another layer of coil 3. An S-bend is set at the starting point of the innermost circle, and its structure is shown in FIG. 3 ....

Abstract

This invention relates to a stator winding of a cylinder-submersible oil linear motor and its winding method characterizing that the stator coil winding is composed of multiple serial single-coke coils and each one is a double-layer structure, one layer is winded clockwise and the other is winded anticlockwise, which is advantaged that the winding structure of the coil is special, and the lead out wires at the two ends are set outside of the coil increasing the power of a linear motor to the utmost and the coil is winded with flat electromagnetic wires so the space of a disk core is fully utilized and the filling rate of the motor groove and section area of the wire are increased greatly and powerless loss of the motor is reduced.

Description

technical field [0001] The invention belongs to a part of a reciprocating type submersible linear motor, in particular to a stator winding of a cylinder type submersible linear motor and a winding method thereof. Background technique [0002] The coil of the existing cylindrical submersible linear motor adopts a circular cross-section electromagnetic wire, which is wound in one direction, and the lead wires come from the inner and outer sides. It is bound to straddle the winding, so it is required to increase the insulation structure, which will occupy the volume and affect the cross-sectional area of ​​the wire in the limited space. Due to the small space in the oil well casing, high power lifting cannot be achieved. Contents of the invention [0003] The purpose of the present invention is to provide a stator winding of a cylindrical submersible linear motor and its winding method. The winding structure of the coil is unique. lift. [0004] The purpose of the present i...
