Technical Field

[0001] This utility model relates to the field of motor rotor technology, and more specifically, to a motor rotor structure that is easy to adjust. Background Technology

[0002] As an important component of a motor, the motor rotor has an easily adjustable structure, which serves several purposes. An easily adjustable motor rotor structure usually means that the winding harness position can be adjusted more easily, thereby optimizing the motor's performance.

[0003] In existing publicly available literature, patent publication number CN113452226A discloses an asynchronous induction motor with a dual-rotor structure. The motor rotor is rotatably connected to the interior of an intermediate stator via an inner rotor, and the inner rotor, intermediate stator, and outer stator together form a dual-rotor structure. This invention simultaneously possesses two structures: a dual-rotor induction motor structure with two rotors inside the outer stator and a dual-rotor induction motor structure with one set of rotors inside and one set outside the intermediate stator. It allows for switching between two motor modes to meet various operating conditions, improving practicality. Furthermore, it is convenient to adjust and simple to operate. However, this technology still has the following problems.

[0004] When the motor rotor structure is in use, the winding harness is wound around the iron core, making it difficult to bind and lock the winding harness according to specific requirements. This easily leads to the winding harness shaking and loosening during use, making it difficult to adjust the motor rotor winding as needed and inconvenient for adjustment. Summary of the Invention

A synchronous adjustment mechanism is provided on the outer wall of the pull cylinder. The synchronous adjustment mechanism includes multiple pull lugs fixedly disposed on the outer wall of the pull cylinder. The inner wall of each pull lug is provided with a winding wire, and an iron core is fixedly connected to the inner wall of the winding wire.

[0007] One end of the rotating rod is fixedly connected to a rotating cap, and the vertical cross-section of the rotating cap is hexagonal.

[0008] When using this technology, hold the stator shaft, the rotating cap drives the rotating rod to rotate, the rotating rod drives the screw to rotate, and at the same time the screw can drive the threaded sleeve block to move to the right under the action of the thread transmission force. The pull cylinder causes multiple pull ears to move to the right synchronously, so that multiple pull ears drive the wire harness part of the winding wire to perform a pulling operation.

[0009] Preferably, a positioning and locking mechanism is provided on one side of the pull cylinder; the positioning and locking mechanism includes a linkage block fixedly disposed on one side of the pull cylinder, and also includes a scale, scale lines, multiple locking holes, a socket block, a pressing bolt, and a rotating cap; a scale fixedly connected to the stator shaft is provided on one side of the linkage block, and scale lines are provided on the upper surface of the scale, multiple locking holes are provided on one side of the scale, the socket block is fixedly connected to the other side of the linkage block, and the pressing bolt is threadedly connected to the inner wall of the socket block, the rotating cap is fixed to the top of the pressing bolt, multiple locking holes are arranged equidistantly from left to right, the vertical cross-section of the locking holes is circular, the rotating cap and the pressing bolt are both made of stainless steel, and the vertical cross-section of the rotating cap is polygonal.

[0010] When this technology is in use, when the pull cylinder moves to the right, it will drive the linkage block to move to the right. The sleeve block will cause the pressing bolt to move to the right, and the rotating cap will move to the right on the scale. When the linkage block moves to the right to the specified distance position, the rotating cap will cause the pressing bolt to rotate, and the pressing bolt will press into the hole on the locking hole.
