Embodiment Construction

[0014] Taking the application of the present invention on an IP23 radially ventilated motor as an example to illustrate its structure and its starting and running method, it is obvious that the present invention is not limited to this type of motor.

[0015] Such as figure 1 , the main stator 1 has the same number of poles as the detachable stator 5, and is fastened into double stators with the same axis through the well-known notches of the casing. Constitute a coaxial dual rotor, the main stator 1 corresponds to the squirrel cage rotor 2, the removable stator 5 corresponds to the solid rotor 6, and they are assembled with the end covers 7 and bearing systems 8 installed at both ends to form a solid rotor A coaxial building block double-stator double-rotor motor operated by a starter squirrel-cage rotor.

[0016] The main stator 1 includes a fixed casing 9 and a stator core with windings connected to the mouth of the fixed casing according to a known structure. The stator co...

Abstract

This invention relates to a double-stator double-rotor motor starting a cage rotor with a solid rotor including stators, rotors, an end cover, a drive shaft and a bearing system charactering in including a cage rotor and a solid rotor installed on a same drive shaft coaxially, a main stator and a shiftable stator, in which, the main stator and the cage rotor make up of an independent cage rotor asynchronous motor, the shiftable stator and the solid rotor constitute an independent solid rotor asynchronous motor and a fan is mounted on the drive shaft.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a double-stator double-rotor motor with a new structure and a starting and running method thereof. Background technique [0002] At present, the largest and most widely used motor in the world is the squirrel-cage rotor asynchronous motor, which has the outstanding advantages of low manufacturing cost, high reliability and good running performance. But its starting performance is particularly unsatisfactory, the starting quality factor is very low, it is difficult to meet the needs of starting with load, it usually uses the method of increasing the motor capacity to achieve the purpose of starting with load, which has caused a serious phenomenon of "big horse and small car" , which not only increases the manufacturing cost of the motor, but also makes the motor run at low load for a long time, wasting a lot of electric energy, and the running performance becomes very p...
