Abstract
The utility model relates to a concentric combined motor, which is mainly characterized in that three concentric stators and three corresponding concentric rotors are arranged in a motor shell, the three concentric stators are fixed on one motor end cap, and the three concentric rotors are fixed on one drive supporting frame which is connected with an output shaft. The concentric combined motor can effectively realize the purpose of designing and manufacturing large power motors or variable power motors, compared with a motor with same power, the concentric combined motor has small volume and light weight, raw materials can be greatly saved, the mounting space is reduced, and the concentric combined motor is in particular suitable for being used in special occasions such as aerospace and the like.
Description
Technical field
The utility model relates to motor, is a kind of concentric combined motor that a more than rotor or stator are arranged.
Background technology
Economizing on resources is the important measures that realize sustainable economic development, and many countries all will economize on resources as a state basic policy.Motor is widely used in every field, and motor of the prior art mainly is made up of motor housing and one group of stator, rotor.So its power of motor of structure generally can only be accomplished 0.6-1kw/kg with the ratio (specific power) of weight.For satisfying the powerful requirement of motor, present major technique measure is to increase motor volume, strengthen stator and rotor, this has just increased the raw material of making motor widely, and the increase of motor volume, weight also influences its serviceability and scope, for example, little, in light weight, the high-power motor of volume is wished to have in fields such as Aero-Space, with the use and the installation requirement that can adapt to the Aeronautics and Astronautics device.For a long time, under vast motor technology personnel's concentrating on studies, motor technology has been obtained significant progress, but the vital volume weight specific power of motor etc. also do not have big breakthrough.
Summary of the invention
The purpose of this utility model is, a kind of concentric combined motor is provided, and makes it realize increasing greatly the purpose of its power under the situation that does not excessively strengthen volume, weight.
Realize the utility model of above-mentioned purpose, have general motor total electric machine casing, motor stator and rotor.Characteristics of the present utility model are, are provided with three concentric stator and three corresponding concentric rotors in electric machine casing, and these three concentric stator are arranged on the motor one end end cap, three concentric rotors be fixed on the joining same transmission bracket of output shaft on.
The utility model can be provided with two concentric rotors between per two concentric stator.
All rotors of the present utility model can all be fixed on the same output shaft with one heart, also can be separately fixed at respectively independently on the concentric output shafts.
The utility model as mentioned above, because of in electric machine casing, being provided with three stators and three rotors with one heart, therefore can realize manufacturing and designing the purpose of heavy-duty motor or change power motor effectively, motor with same power compares, the utility model volume is little, in light weight, can save raw material widely and reduce installing space.Be particularly suitable for using as special occasions such as Aero-Space.
Description of drawings
Fig. 1 is the cross-sectional schematic of an embodiment of the utility model.
Fig. 2 is the cross-sectional schematic of another embodiment of the utility model.
Embodiment
An embodiment of the present utility model as shown in Figure 1.See by Fig. 1, the utility model is installed with three concentric stator that are made of stator core 4 and stator winding 2 and at three corresponding concentric rotors on the motor left end cap 1 in electric machine casing 3, these three concentric rotors are fixed on the same rotor transmission bracket 6 by three rotor magnetic steels 5 and form, and this rotor transmission bracket structure 6 is connected into one with output shaft 8 again.
Another embodiment of the present utility model as shown in Figure 2.See by Fig. 2, present embodiment is, in electric machine casing 3, be provided with three concentric stator that include stator winding 9,10,11 and stator core 12,13,14, all be fixed on the motor left end cap 1, correspondingly be provided with three concentric rotors that include rotor magnetic steel 15,16,17 and rotor transmission bracket 18,19,20, but the rotor magnetic steel 15,16,17 that constitutes these three concentric rotors is separately fixed at respectively independently on three transmission bracket 18,19,20.Three transmission bracket 18,19,20 also are separately fixed at independently on the concentric output shafts 21,22,23.
Claims (4)
