The purpose of this utility model is to be achieved by following technical scheme.

A kind of rotor assembly, comprise rotating shaft, rotor core and be installed in some permanent magnets of rotor core lateral surface, the rotor core two ends are equipped with end plate, the end plate outer ledge extends some T type dividing plates, separating part in the middle of the T type dividing plate is installed between adjacent two permanent magnets, and the fastener of T type dividing plate outside is close to and is pressed on the permanent magnet outside wall surface.

The end face of above-mentioned described end plate is provided with some container cavities.

Above-mentioned described some container cavities are along circumferentially being evenly distributed on the end plate, and wherein partly container cavity is placed the balance clay.

The outside of above-mentioned described permanent magnet and end plate is nested with outer sleeve.

The material of making of above-mentioned described end plate is a non-magnet material.

One end face of above-mentioned described end plate sticks with glue at the end face of rotor core.

The quantity of above-mentioned described T type dividing plate equates that with the quantity of permanent magnet T type dividing plate evenly circumferentially is distributed on the end plate.

The quantity of above-mentioned described some T type dividing plates is 8, and the quantity of permanent magnet also is 8.

The material of making of above-mentioned described end plate is plastic cement or steel.

The utility model beneficial effect compared with prior art is: 1) a kind of rotor assembly, comprise rotating shaft, rotor core and the some permanent magnets that are installed in the rotor core lateral surface, the rotor core two ends are equipped with end plate, the end plate outer ledge extends some T type dividing plates, separating part in the middle of the T type dividing plate is installed between adjacent two permanent magnets, the fastener of T type dividing plate outside is close to and is pressed on the permanent magnet outside wall surface, make the permanent magnet installing space even, solve the not uniform and noise that brings of permanent magnet, vibration problems, make the operation that permanent magnet is installed simple, improve installation effectiveness; 2) side of end plate is provided with some container cavities, and some container cavities are along circumferentially being distributed on the end plate, and wherein partly container cavity is placed the balance clay, and clay is proofreaied and correct rotor dynamic balancing, and container cavity is used for filling the balance clay, effectively reduces the probability that the balance clay comes off; 3) outer of permanent magnet is nested with outer sleeve, and rotor has been carried out triple protection, suppresses coming off of magnetic shoe, end plate simultaneously; 4) material of making of end plate is a non-magnet material, effectively prevents rotor leakage; 5) quantity of T type dividing plate equates with the quantity of permanent magnet, evenly circumferentially is distributed on the end plate, makes the permanent magnet accurate positioning, and spacing is even.
