Abstract
The utility mode relates to a multiple stator and rotor combined electric motor which is characterized in that a plurality of concentric stators and corresponding concentric rotors are arranged in an electric motor housing, and the concentric rotors are fixed on a transmission bracket which is connected with an output shaft. The electric motor can effectively realize the purpose for designing and manufacturing a high power electric motor and a variable power electric motor. Compared with the same power electric motor, the combine electric motor has smaller volume, lighter weight, material saving and reduction of installation space, and is especially suitable for special occasions such as aerospace, and the like.
Description
Technical field
The present invention relates to motor, is a kind of motor of multiple stator and rotor combination type 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 objective of the invention is, a kind of motor of multiple stator and rotor combination type is provided, make it under the situation that does not excessively strengthen volume, weight, realize increasing greatly the purpose of its power.
Realize the present invention of above-mentioned purpose, have general motor total electric machine casing, motor stator and rotor.Characteristics of the present invention are, are provided with a plurality of concentric stator and corresponding concentric rotor in electric machine casing, concentric rotor be fixed on the joining transmission bracket of output shaft on.
The said a plurality of concentric stator of the present invention can be arranged on the motor one end end cap.
The present invention can be provided with two concentric rotors between per two concentric stator.
All rotors of the present invention 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 present invention can be provided with three concentric stator and three corresponding concentric rotors in electric machine casing, 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 present invention as mentioned above, because of in electric machine casing, being provided with a plurality of stators and a plurality of rotor 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, volume of the present invention 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.
