Description
Technical field:
The utility model relates to a kind of ground structure of plastic packaging motor.
Background technology:
The tradition dc brushless motor in order to remove static and unnecessary electric current, all with the structure of motor stator, these static and unnecessary electric current are drawn outside the motor by ground connection, guarantee motor normal reliable trouble free service.For some dc brushless motors that adopts metal end, stator core can be linked to each other with metal end, static on the stator core and unnecessary electric current are taken away by metal end; But for the dc brushless motor of insulation crust, this mode is no longer suitable.
The purpose of stator grounding is: a. can test the insulation status between winding coil and the stator core, and monitoring motor safety quality prevents security incident; B. improve EMC, promptly remove static.
The following problem of ground structure ubiquity at the dc brushless motor of insulation crust: complex structure, the manufacturing cost height is installed and used cumbersome.
Summary of the invention:
The purpose of this utility model provides a kind of ground structure of simple and reasonable, safe and reliable, the easy to manufacture and plastic packaging motor that cost is low.
The technical solution of the utility model is achieved in that
A kind of ground structure of plastic packaging motor, comprise stator core, be embedded in overhang insulation on the stator core, be wrapped in the coil windings on the overhang insulation and be injection-moulded in housing on stator core, overhang insulation and the coil windings, wherein in the cavity of housing, control circuit board is installed, be connected with metalwork one end on the stator core, the other end of metalwork passes housing and enters cavity and be communicated with ground connection place on the control circuit board.The utility model is connected with stator core by metalwork, and the metalwork plastic packaging is on housing, and the other end of metalwork connects control circuit board, utilize the ground connection place on the control circuit board that static and unnecessary electric current are drawn outside the motor, simple and reasonable, implement easily, low cost of manufacture, safe and reliable.
The motor outside can be drawn by lead by ground connection place on the above-mentioned described wiring board, implements easy and convenient.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is the A-A enlarged drawing of Fig. 1.
Embodiment:
As shown in Figure 1 and Figure 2, the utility model comprises stator core 1, be embedded in overhang insulation 8 on the stator core 1, be wrapped in the coil windings 2 on the overhang insulation 8 and be injection-moulded in housing 3 on stator core 1, overhang insulation 8 and the coil windings 2, wherein in the cavity 4 of housing 3, control circuit board 5 is installed, be connected with metalwork 6 one ends on the stator core 1, the other end of metalwork 6 passes housing 3 and enters cavity 4 and be communicated with ground connection place on the control circuit board 5.The motor outside can be drawn by lead 7 by ground connection place on the control circuit board 5.
Operation principle of the present utility model is: in the course of work, stator core 1 produces non-essential electric current, can locate by the ground connection that metalwork 6 is guided on the control circuit board 5, draws the motor outside by lead 7 again.Certainly the static that produces can be taken away by above-mentioned loop.
