Description

Technical Field

[0001] The utility model belongs to the technical field of motor coils, and in particular relates to a lead structure of a permanent magnet synchronous motor coil. Background Art

[0002] The principle of the claw-pole permanent magnet synchronous motor can be simply understood as a rotating magnet attracting another magnet to rotate together. The key of the claw-pole permanent magnet synchronous motor is that the claw pole is magnetized by the coil. Because it is alternating current, according to the right-hand rule, the solenoid NS poles alternate, and the claw pole NS also alternates, which is similar to a rotation of one grid, which is equivalent to a rotating magnet. Claw-pole permanent magnet synchronous motors are generally used as electric valve actuators, medical equipment, and precision machinery transmissions.

[0003] At present, after the lead wires on the claw-pole permanent magnet synchronous motor coil are wound, there is a problem of too much left at the head and tail ends of the lead wires. In order to prevent the two lead wire ends from accidentally touching and causing a short circuit due to the reserved too much, the excess lead wires are manually cut off, which causes cumbersome cutting operations and the trouble of cutting too much. Therefore, a lead wire structure for the permanent magnet synchronous motor coil is needed to solve the problems existing in the prior art. Utility Model Content

[0006] It should be noted in the solution that a positioning guide groove is provided on one side of the surplus wire accommodating frame, and the positioning guide block is slidably connected in the positioning guide groove of the surplus wire accommodating frame.

[0007] It is further worth mentioning that a telescopic sliding hole is provided on one side surface of the positioning guide block, and the horizontal cross bar is slidably matched with the telescopic sliding hole of the positioning guide block.

[0008] It should be further explained that fixed supports are fixed to both edges of the front surface and the rear surface of the excess wire accommodating frame, and both ends of the horizontal cross bar are respectively fixed between two adjacent fixed supports.

[0009] As a preferred embodiment, one end of the return spring is fixed to an end surface of a fixed support, and the other end of the return spring is fixed to the positioning guide block.

[0010] As a preferred embodiment, a threading disk is fixed at the center of the upper surface of the coil skeleton disk, one end of the lead head passes through the threading disk, and the lead head is sequentially wound and arranged between a row of first extrusion columns and a row of second extrusion columns.

[0011] Compared with the prior art, the lead structure of a permanent magnet synchronous motor coil provided by the present invention has at least the following beneficial effects:

[0012] Through the set excess wire retraction mechanism, the lead head is bent back and forth and stored on the first extrusion column and the second extrusion column, thereby reducing the trouble of cutting the two lead heads shorter to ensure safe use due to excessive reservation. In addition, the winding method of the first extrusion column and the second extrusion column is provided with multiple groups that can greatly shrink the effective use length of the lead head.

[0013] By providing an elongation adjustment mechanism, the distance between the first extrusion column and the second extrusion column is adjusted when the lead head is stretched, so that the effective use length of the lead head can be adaptively stretched during wiring use.
