Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
As Fig. 1, Fig. 2 and the expressed structure of the present utility model of Fig. 3, the utility model is a kind of hybrid power automobile drive electric motor, and the rotor of this motor adopts mouse cage type structure; Its stator adopts and laminates silicon steel sheet and be embedded in magnet exciting coil at its line embedding groove.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realization reduces the drive motors cost, improves the goal of the invention of its efficient, the technical scheme that the utility model is taked is: as depicted in figs. 1 and 2, this hybrid power automobile drive electric motor that is provided, the iron core of its cage rotor is to be formed by the silicon steel plate stacking that has a plurality of rotor, the center line of groove is parallel with rotor axis and be distributed in the direction of the circumference of rotor, establishes the rotor bar 2 that copper product makes and inserts in the above-mentioned groove; Establish the rotor short-circuit ring 4 that copper product is made in its end; Rotor bar 2 is fastenedly connected with rotor short-circuit ring 4.
Be the copper rotor structure as shown in Figure 1 and Figure 2, inserting copper conductor in the rotor is the rotor bar 2 that copper material is made.In order to improve the performance of cage type induction motor, the resistance of rotor bar 2 and rotor short-circuit ring 4 must be little.But the conductance that the existing conductor that is applicable to above-mentioned rotor obtains is lower than copper, so caused the low problem of induction machine characteristic, this also is the reason that hybrid vehicle is seldom selected induction machine for use.The final purpose of hybrid power will reduce oil consumption exactly, and this just requires the efficient of car load must be quite high, and 60%～70% efficient of common induction machine is not reach requirement far away.So select to adopt copper rod to be inserted into the cage type induction motor rotor structure.The induced current and the magnetic flux interaction that produce by stator coil produce moment of torsion.
