Abstract
The utility model relates to a novel electric motor with security function, which comprises a stator, a rotor and a coil, wherein the stator comprises a stator metal core and a casing, an insulating layer is arranged between the stator and the rotor, the stator and the rotor are respectively connected with a stator sampling wire and a rotor sampling wire which are arranged at the secondary circuit with a protector. The insulting layer is employed in the electric motor, thereby when the stator and the rotor are damaged by the bearing or the bearing bush of the bearing seat damage, the running power of the electric motor is not passed to the casing, thereby protecting the security of the operator. The stator sampling wire and the rotor sampling wire also form a cycle circuit, which can make the electric motor power-off quickly and protect the bearing, the bearing bush and the bearing seat from being burned off. In maintenance, only the bearing, the bearing bush and the bearing seat are repaired, the electric can be used again, which effectively reduces the damage of the electric motor and extends the service life of the whole electric motor.
Description
Technical field:
The utility model relates to motor, and particularly a kind of security performance is good, not fragile, has the New-type electric machine of safety protection function.
Background technology:
Motor is the power source of using always, is widely used in various fields, and it mainly is made up of shell, stator, rotor and coil, and structure is relatively stable.In the prior motor use, but usually because rotor bearing or bearing shell and bearing bit loss are bad, cause rotor collision stator to produce friction damage, the overheated coil that burns out, motor can't be worked, and can only stop work, and maintenance difficulty is big, time-consuming, effort sometimes because of maintenance cost is big, can only be done discarded the processing.
The utility model content:
The purpose of this utility model exactly will for the public provide a kind of simple in structure, security performance good, has the New-type electric machine of safety protection function.
The utility model comprises stator, rotor and coil; stator comprises stator core and shell; different is: be provided with insulating barrier between stator and rotor; be connected with stator sample line and rotor sample line on stator and rotor respectively, rotor sample line and stator sample line are connected in the secondary circuit that is provided with protector.
Described insulating barrier is arranged between the outer border of stator core and the shell or two ends of rotor lid and the equipped position of shell.
Described rotor sample line can be arranged on rotor or connect on the conductive parts with rotor.
Described stator sample line is arranged on stator core or the shell.
General motor when operate as normal, once take place bearing or bearing shell and bearing bit loss bad after, rotor just collides stator and produces friction and burn out motor, causes rotor, stator and coil all charged, operating personnel are as getting an electric shock easily because of carelessness; The utility model is because of being provided with insulating barrier between stator and rotor, when rotor and stator because of bearing or bearing shell and the bearing bit loss is bad when being damaged, the motor rotation power supply can not pass on the shell, has effectively protected operating personnel's safety.Simultaneously, rotor collision stator core, the rotor sample line and the stator sample line that are connected in the secondary circuit that is provided with protector form the loop, and motor is cut off the power supply at once, form a kind of effective protection, and can be because of overheated around ring coil; Like this, during maintenance,, can re-use, effectively protect the damaged condition of motor, prolong the whole service life of motor as long as fix bearing, bearing shell and bearing position.
Description of drawings:
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among Fig. 1: 1 shell, 2 stator cores, 3 coils, 4 rotors, 5 insulating barriers, 6 rotor sample lines, 7 stator sample lines, 8 protectors.
