Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, in particular to a permanent magnet motor rotor assembly device. Background Art

[0002] A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field. It does not require an excitation coil or excitation current, so it has significant advantages such as simple structure, reliable operation, small size, light weight, low loss, and high efficiency. A permanent magnet motor consists of a stator and a rotor. The stator is usually composed of an iron core and a winding, while the rotor is composed of a shaft and magnetic poles. When current passes through the stator winding, a magnetic field is generated around the winding. This magnetic field interacts with the magnetic field generated by the permanent magnet to generate torque, thereby driving the motor to rotate.

[0003] With the rapid development of science, technology and economy in my country, high-speed centrifugal blowers are used in more and more scenarios. However, during the assembly process of high-speed centrifugal blowers, since most of their motor rotors are permanent magnet rotors, there will be a large suction force between the casing and the stator, making it difficult to locate the center position, and it is easy to scratch the rotor and stator. The end covers on both sides have high precision, and the assembly gap with the casing is very small, making installation difficult. Workers must undergo professional training before they can operate, and their work efficiency is low.

[0004] Therefore, a permanent magnet motor rotor assembly device is proposed. Summary of the invention
