Abstract
The utility model relates to a rotor structure of an electric vehicle range extender, which is composed of a rotor bracket, retainer rings, rotors and magnetic steel, wherein the magnetic steel is installed in internal grooves of the rotors, the retainer rings are installed on a front end face and a rear end face of the rotor, and the retainer rings and the rotors are sleeved on an outer circle of the rotor bracket. According to the rotor structure of the electric vehicle range extender provided by the utility model, rotors are not easy to fall off during working, the shape of the magnetic steel is simple, the manufacture is convenient, and the rotor structure has the advantages of economy and practicality.
Description
Technical field
The utility model relates to a kind of rotor structure, especially a kind of electric motor car distance increasing unit rotor structure.
Background technology
Common rotor structure because of magnet steel is contained in the outside of rotor, causes rotor when work, and magnet steel comes off easily, causes serious accident, and the magnet steel complex contour, and is very uneconomical.
The utility model content
The problem that the utility model will solve is the deficiency that overcomes in the background technology, and a kind of electric motor car distance increasing unit rotor structure is provided, this electric motor car distance increasing unit rotor structure; With the magnet steel internal rotor of packing into, magnet steel difficult drop-off during work, the simple shape of magnet steel simultaneously; Easily manufactured, economical and practical.
For addressing the above problem, the utility model is taked following technical scheme:
A kind of electric motor car distance increasing unit rotor structure of the utility model is made up of rotor field spider, back-up ring, rotor, magnet steel, and magnet steel is packed in the inside groove of rotor, and the rear and front end face of rotor is installed back-up ring, and back-up ring and rotor are enclosed within on the cylindrical of rotor field spider together.
A kind of electric motor car distance increasing unit rotor structure of the utility model, owing to be made up of rotor field spider, back-up ring, rotor, magnet steel, magnet steel is packed in the inside groove of rotor; The rear and front end face of rotor is installed back-up ring; Back-up ring and rotor are enclosed within on the cylindrical of rotor field spider together, thus rotor when work magnet steel be not easy to come off and the simple shape of magnet steel; Easily manufactured, have economical and practical advantage.
