Abstract

The invention discloses a rotor part of a frequency conversion motor and the frequency conversion motor. The rotor part of the frequency conversion motor comprises: a rotor iron core, a magnet slot is arranged in the rotor iron core, and the magnet slot is a first slot and a second slot. One of the two slots; the rotor magnet, the rotor magnet is one of the first permanent magnet and the second permanent magnet, and is installed in the magnet slot; the first rotor end plate and the second The rotor end plate, and the first rotor end plate is provided with a limit boss against the rotor magnet; wherein when the rotor magnet is the first permanent magnet or the second permanent magnet, the The first rotor end plate has a first projection or a second projection, and the limiting boss is arranged in an overlapping area of ​​the first projection and the second projection. For the rotor component of the frequency conversion motor in the embodiment of the present invention, by designing the first rotor end plate with the above structure, the application range of the first rotor end plate can be expanded, thereby reducing the quantity of materials and reducing the manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a rotor component of a variable frequency motor and a variable frequency motor with the rotor component. Background technique [0002] The variable frequency motor of the refrigerator compressor has rotor components, and the rotor components often use two types of rotor magnets: ferrite permanent magnets and rare earth permanent magnets, to meet the requirements of different magnetic flux densities under the same inner and outer diameter of the rotor. Due to the difference in material properties between the ferrite permanent magnet and the rare earth permanent magnet, the size of the rotor magnet corresponding to the two rotor parts and the size of the magnet slot on the rotor core are different. In the related art, in the production of these two rotor parts, in order to prevent the limit boss of the rotor end plate from touching the rotor core, it is nece...
