Description
Technical field
The utility model relates to stepping motor technical field, especially a kind of heat dissipation type stepping motor.
Background technology
Increasingly mature and perfect along with technology, stepping motor obtains fast development, usually all kinds of motors seen, inside is all cored and winding coil, and winding has resistance, and energising can produce loss, square being directly proportional of loss size and resistance and electric current, our copper loss of often saying that Here it is, if electric current is not direct current or the sine wave of standard, also can produce harmonic loss; Iron core has magnetic hysteresis eddy current effect, also loss can be produced in alternating magnetic field, its size and material, electric current, frequency, voltage is relevant, this is iron loss, and copper loss and iron loss all can show with the form of heating, thus affect the efficiency of motor, stepping motor ubiquity heat condition, and situation is more serious than general alternating current machine, the too high meeting of temperature makes magnet steel demagnetize, and also cuts off the electricity supply not in time just like generation stall, the damage of motor and some relevant devices can be caused, and the complex structure that traditional stepping motor heat radiation adopts.
Utility model content
The technical problems to be solved in the utility model is: serious in order to solve stepping motor heating, now provides a kind of heat dissipation type stepping motor.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat dissipation type stepping motor, comprise housing, stator core is provided with in described housing, described stator core is wound with enamelled wire, also comprise insulating heat-conductive silica gel, described insulating heat-conductive silicone filler is between stator core and enamelled wire, during machine operation, enamelled wire can produce heat, the heat of enamelled wire is diffused into rapidly on stator core, distribute further in air, insulating heat-conductive silica gel has high thermal conductivity, splendid thermal conductivity, the exhausted property of good electricity, wider serviceability temperature, good stability in use, its high-adhesion can be that between enamelled wire and stator core, heat transmits very fast, well the space of enamelled wire can be filled up and can also insulate simultaneously.
In order to the heat making heat conductive silica gel be delivered on housing is dispersed in air in time, further, also comprise some fin, described fin is uniformly distributed on the housing, increases area of dissipation.
Preferably, the cross section of described fin is rectangle.
Preferably, between described fin and housing, angle is 45 °.
The beneficial effects of the utility model are: heat dissipation type stepping motor of the present utility model by filling insulating heat-conductive silica gel between enamelled wire and stator core, the heat of enamelled wire is diffused into rapidly on stator core, distribute further in air, motor radiating performance is increased, thus improve the load current of motor, increase the load capacity of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 schematic diagram of the present utility model;
In figure: 1, housing, 2, stator core, 3, enamelled wire, 4, fin.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
A kind of heat dissipation type stepping motor as shown in Figure 1, comprise housing 1, stator core 2 is provided with in housing 1, stator core 2 is wound with enamelled wire 3, also comprises insulating heat-conductive silica gel, insulating heat-conductive silicone filler is between stator core 2 and enamelled wire 3, also comprise some fin 4, fin 4 is evenly distributed on shell 1, and the cross section of fin 4 is rectangle, and between fin 4 and housing 1, angle is 45 °.
Operation principle:
Insulating heat-conductive silicone filler is between stator core 2 and enamelled wire 3, during machine operation, enamelled wire 3 can produce a large amount of heats, and the heat of enamelled wire 3 is diffused into rapidly on stator core 2, and the fin 4 on housing 1 adds area of dissipation, distribute further in air.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
