Abstract
The utility model provides a kind of high security brushless electric machine, comprise stator and be rotatably installed to the rotor of stator center, described stator comprises stator core and is set around the stator winding on stator core, described rotor comprises motor shaft and is fixed on the rotor core on motor shaft, in described stator core, table is also fixedly pasted with one deck bakelite plate; The utility model arranges one deck bakelite plate on stator core inner surface, when not affecting motor and normally working, stators and rotators is separated, even sweep thorax phenomenon, also can not be short-circuited because of grazing mutual between stators and rotators, the situation of motor damage; Meanwhile, due to the existence of bakelite plate, also can prevent stator winding from deviating from from stator core, structure is simple, easy to operate, safe and reliable, is suitable for promoting.
Description
Technical field
The utility model relates to technical field of motors, especially a kind of high security brushless electric machine.
Background technology
Stator core and rotor core are all built up by the silicon steel sheet of mutually insulated, and be the magnetic circuit part of motor, stator does not turn, rotor turns, so the air gap of theirs therebetween must have.And air gap between stator and rotor is very little, in small-capacity motor, air gap only has 0.5mm to 3mm, due to bearing excessive wear or assemble not in place, is easy to cause between stator and rotor and wipes mutually, make iron core surface damage, and then causing short circuit between silicon steel sheet, the iron loss of motor increases, and makes motor temperature too high, easily cause motor damage, there is potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is: in order to solve the problem causing motor damage between stators and rotators owing to sweeping thorax, provides a kind of high security brushless electric machine.
The utility model solves the technical scheme that its technical problem will adopt: a kind of high security brushless electric machine, comprise stator and be rotatably installed to the rotor of stator center, described stator comprises stator core and is set around the stator winding on stator core, described rotor comprises motor shaft and is fixed on the rotor core on motor shaft, it is characterized in that: in described stator core, table is also fixedly pasted with one deck bakelite plate, bakelite plate has good insulation, rub resistance and heat-resisting quantity.
The beneficial effects of the utility model are: the utility model arranges one deck bakelite plate on stator core inner surface, when not affecting motor and normally working, stators and rotators is separated, even sweep thorax phenomenon, also can not to be short-circuited because of grazing mutual between stators and rotators, the situation of motor damage; Meanwhile, due to the existence of bakelite plate, also can prevent stator winding from deviating from from stator core, structure is simple, easy to operate, safe and reliable, is suitable for promoting.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model high security brushless electric machine.
In figure: 1, stator, 1-1, stator core, 1-2, stator winding, 2, rotor, 2-1, motor shaft, 2-2, rotor core, 3, bakelite plate.
Embodiment
By reference to the accompanying drawings the utility model is described in detail now.This figure is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
With reference to shown in Fig. 1, the high security brushless electric machine that the utility model provides, comprise stator 1 and be rotatably installed to the rotor 2 at stator 1 center, described stator 1 comprises stator core 1-1 and is set around the stator winding 1-2 on stator core 1-1, described rotor 2 comprises motor shaft 2-1 and is fixed on the rotor core 2-2 on motor shaft 2-1, in described stator core 1-1, table is also fixedly pasted with one deck bakelite plate 3, bakelite plate 3 has good insulation, rub resistance and heat-resisting quantity.
The utility model arranges one deck bakelite plate 3 on stator core 1-1 inner surface, when not affecting motor and normally working, stator 1 and rotor 2 are separated, even sweep thorax phenomenon, also can not be short-circuited because of grazing mutual between stator 1 and rotor 2, the situation of motor damage; Meanwhile, due to the existence of bakelite plate 3, also can prevent stator winding 1-2 from deviating from from stator core 1-1, structure is simple, easy to operate, safety and stability, is suitable for promoting.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff not departing from scope of the present utility model, 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.
