Description
Technical field
The utility model relates to electric bicycle technical field, particularly relates to the quill shaft heat radiating type motor that a kind of electrical salf-walking is automobile-used.
Background technology
As everyone knows, electric bicycle is the new traffic tool using electric energy as supplementary energy; In recent years, along with the fast development of path to urbanization, it is increasingly serious that environmental problem, resource problem and traffic blocking problem become, and therefore, the advantage that electric bicycle is light with it, clean has and more is subject to liking of people.
As everyone knows, storage battery and motor are two large parts of electric bicycle power source, and storage battery is for electric bicycle provides the energy storage device of electric energy, and motor converts electrical energy into mechanical energy and then provides the energy transition equipment of power resources for electric bicycle, at present, the motor that electric bicycle uses mainly external rotor electric machine, because electric bicycle is mainly with lightly, convenient is major design principle, therefore there is certain structural difference in the motor that adopts of electric bicycle and conventional motors, the motor that such as conventional electric automobile adopts is mainly inner rotor motor, what electric bicycle then adopted is external rotor electric machine, owing to being subject to the restriction of volumetric spaces, therefore the motor heat that electrical salf-walking is automobile-used is difficult to Quick diffusing and goes out, so, it is large to there is thermal losses in the motor of conventional electric bicycle use, efficiency low conversion rate, the defect that operating ambient temperature is high, if continuous working period is longer, the hazard event of motor burning is very easily caused to occur.
Utility model content
The technical problems to be solved in the utility model is: provide the quill shaft heat radiating type motor that a kind of perfect heat-dissipating, thermal losses is low, coefficient of safety is high electrical salf-walking are automobile-used.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
The quill shaft heat radiating type motor that electrical salf-walking is automobile-used, described motor is external rotor electric machine; Described quill shaft heat radiating type motor comprises rotor, stator core, motor quill shaft, bearing, motor wheel hub and permanent magnet; Wherein: motor two side ends cover screw is fixed on motor wheel hub, described stator core inside is wound with winding, described stator core is fixed on motor wheel hub inside, described motor quill shaft is fixed on the inside of stator core, described bearing and oil sealing are arranged on inside end cap, and described end cap and motor quill shaft pass through bearings; Described motor quill shaft end winding support is on electromobile frame.
The advantage that the utility model has and good effect are:
Because the motor shaft in the utility model adopts hollow structure, therefore compared with conventional art: in the process used, the heat energy that motor produces can fast and effeciently be distributed by air-cooled form, and then ensure that motor is in a relatively low operate at ambient temperature, therefore there is perfect heat-dissipating, thermal losses is low, power of motor density is high, the efficiency of motor is high, and coefficient of safety is high, the advantage that extends motor useful life.
Accompanying drawing explanation
Fig. 1 is end view drawing of the present utility model
Fig. 2 is axial section of the present utility model;
Wherein: 1, stator core; 2, bearing; 3, oil sealing; 4, motor quill shaft; 5, motor wheel hub; 6, screw; 7, winding; 8, end cap.
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the quill shaft heat radiating type motor that a kind of electrical salf-walking is automobile-used, the motor in this preferred embodiment is external rotor electric machine; Described quill shaft heat radiating type motor comprises rotor, stator core 1, motor quill shaft 4, bearing 2, motor wheel hub 5 and permanent magnet; Wherein: motor both sides end cap 8 is fixed on motor wheel hub 5 by screw 6, stator core 1 inside is wound with winding 7, it is inner that stator core 1 is fixed on motor wheel hub 5, motor quill shaft 4 is fixed on the inside of stator core 1, bearing 2 and oil sealing 3 are arranged on inside end cap 8, and end cap 8 and motor quill shaft 4 are supported by bearing 2; Motor quill shaft 4 end winding support is on electromobile frame.
Because the motor shaft in the utility model adopts hollow structure, therefore in the process used, the heat energy that motor produces can fast and effeciently be distributed by motor quill shaft 4 by air-cooled form, and then ensureing that motor is in the relatively low operate at ambient temperature safe working temperature of motor (i.e. within the scope of), the technical scheme therefore in above-mentioned specific embodiment has perfect heat-dissipating, thermal losses is low, coefficient of safety is high advantage; The useful life of motor can be extended to a certain extent simultaneously.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
