Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1-8 As shown, this utility model provides a technical solution: a quick-install frameless motor, including a rotor 1, a stator 2 disposed on the outer side of the rotor 1, and an installation assembly disposed on the outer side of the stator 2. A first fixing ring 5 is connected to the bottom of the installation assembly, and the first fixing ring 5 is used to install the stator 2 in the area to be installed. The installation assembly includes a positioning frame 3 and a connecting shell 4 respectively disposed on the top and bottom of the stator 2. The connecting shell 4 is a hollow structure, and the positioning frame 3 and the connecting shell 4 are snapped together to limit and support the stator 2. A first locking block 12 and a second locking block 13 are also disposed between the connecting shell 4 and the first fixing ring 5. The first locking block 12 is connected to the connecting shell 4 through a pressing assembly. The bottom of the second locking block 13 is fixedly connected to the top of the first fixing ring 5, and the top of the second locking block 13 is snapped with the bottom of the first locking block 12 to fix the connecting shell 4 and the first fixing ring 5. The pressing assembly is also connected to a reset assembly, which drives the first locking block 12 away from the second locking block 13 to separate the connecting shell 4 and the first fixing ring 5.

[0033] In use, the first fixing ring 5 is annular and fixed to the existing installation area, such as the stop of the equipment housing, by bolts. Simultaneously, the positioning frame 3 and connecting shell 4 are clamped and fixed to the outside of the stator 2. Then, the first locking block 12 and the second locking block 13 are engaged to fix it to the first fixing ring 5, facilitating quick disassembly and installation of the stator 2. The first locking block 12 is L-shaped, and the second locking block 13 has an arrow-shaped cross-section. During installation, the first fixing ring 5 is first fixed, then the positioning frame 3 and connecting shell 4 are installed on the outside of the stator 2. The first locking block 12 is then aligned with the second locking block 13, and pressed against the second locking block 13 to insert it into the stator. Inside the connecting shell 4, the first locking block 12 is pushed to rotate to the side by the inclined surface at the top of the second locking block 13, and the pressing component is pressed. After the first locking block 12 moves to the widest part of the arrow of the second locking block 13 inside the L-shaped part, the pressing component pushes the first locking block 12 towards the second locking block 13 and presses against the second locking block 13, thereby achieving the engagement of the second locking block 13 and locking the connecting shell 4 and the first fixing ring 5, restricting their upward movement; at the same time, the movable space for the first locking block 12 at the bottom of the connecting shell 4 to move to both sides is the first sliding groove 19, the width of which is adapted to the first locking block 12 and the second locking block 13, further restricting its horizontal movement to ensure the stability of fixing the stator 2.

Then, the retaining ring 7 is rotated six times. After ten degrees, that is, after the first opening position corresponds to the fourth opening position on the top of the connecting shell 4, the positioning frame 3 extends downward along the third opening on the outer wall of the stator 2, so that the positioning frame 3 is inserted into the interior of the connecting shell 4. Then, the release block is used to reset the retaining ring 7 under the push of the first elastic component, so that the edge of the retaining ring 7 rotates and inserts into the second opening, restricting the up and down movement of the positioning frame 3. At the same time, the connecting shell 4 restricts the rotational movement of the positioning frame 3, thereby pressing and fixing the positioning frame 3 and the connecting shell 4 to both ends of the stator 2, realizing the limiting support of the stator 2, so as to connect with the first fixing ring 5 and quickly install the stator 2.
