Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motors and relates to a stator and rotor, in particular to a combined stator and rotor. Background Art
[0002] The stator and rotor in the motor are indispensable components of the motor. They work together to achieve the conversion between electrical energy and mechanical energy. The stator plays the role of generating a magnetic field in the motor. When alternating current is passed through the stator winding, a rotating magnetic field is generated. This rotating magnetic field interacts with the rotor winding to generate electromagnetic torque, thereby driving the rotor to rotate.
[0003] The stator in a conventional motor is fixed in the housing, and both ends of the rotor are fixed in the housing. During disassembly and maintenance, the cover at one end needs to be removed to achieve disassembly and rotation. Usually, clips or bolts are used to fix them, which makes disassembly complicated or easy to damage. Summary of the invention

When installing, the limiting blocks 3 are clamped into the mounting rod 6, and then the mounting rod 6 is aligned with the clamping protrusion 9. The limiting blocks 3 are moved so that the limiting blocks 3 clamp the mounting rod 6 and the clamping protrusion 9 at the same time, so that the transmission shaft and the bearing 7 are connected as a whole.

Before installation, the shrinking cone 19 is clamped with the limiting block 3. During installation, the shrinking cone 19 is pressed and the limiting block 3 is moved. After the installation is completed, the limiting block 3 is restricted from being installed to prevent the limiting block 3 from being located and causing the installation to be detached.
