Structure.
Background technology
Brshless DC motor is made of motor body and driver, is a kind of typical electromechanical integration brushless dc
Machine.The stator winding of motor makes three-phase symmetrical star connection more, quite similar with threephase asynchronous.Motor turns
The permanent magnet to have magnetized is stained on son, in order to detect the polarity of motor rotor, in the built-in position sensor of motor.Driving
Device is made of power electronic device and integrated circuit etc., and function is：The startup, stopping, brake signal for receiving motor, with control
Startup, stopping and the braking of motor processed；Receive position sensor signal and positive and negative rotaring signal, for controlling each power of inverter bridge
The break-make of pipe generates continuous torque；Receive speed command and feedback speed signal, for controlling and adjusting rotating speed；Protection is provided
With display etc..
Based on the performance that brshless DC motor is excellent, many fields are required for applying, however in miniature brushless direct-current motor
In, a long threaded rod is usually arranged in the closing component structure between shell and upper flange inside housings, then will be upper by screw
Flange is fixed in the housing；However this mode can occupy the space of enclosure interior, increase the volume of motor, be unfavorable for micro electric
The installation of machine.
Utility model content
The purpose of this utility model is to provide a kind of miniature brushless direct-current motors to have solved the problems in background technology.
A kind of self-locking structure of miniature brushless direct-current motor, including shell and upper flange, the shell are cylindric, shell
Inner wall be smooth surface, the upper ends of inner walls has internal thread；The lower end of the upper flange has matches with the internal thread
The external screw thread of conjunction, the upper end of the upper flange have the rib portion to extend internally, have in the rib portion and be arranged straight down
Threaded hole, there is at the inner wall of upper flange thread groove corresponding with threaded hole, one section of self tapping spiral shell is additionally provided with below thread groove
Silk slot.
Further, there are three the threaded hole is set, and mutually two-by-two apart from equal setting.
Further, there are three the hollow slots for appearing iron core for tool in the rib portion.
The beneficial effects of the utility model are：By the setting for cancelling stud so that the volume of shell itself is reduced, upper method
It is fixedly connected by way of screw-thread fit between blue and shell, under in addition also corresponding to threaded hole at the inner wall of upper flange
Side is equipped with self-tapping screw slot, and is pierced from threaded hole by self-tapping screw, and will carry out slicing to self-tapping screw slot, with
The mode of thread binding cooperates so that the combination between upper flange and shell is even closer.

Further, there are three the threaded hole 23 is set, and mutually two-by-two apart from equal setting.
Further, there are three the hollow slots 26 for appearing iron core for tool in the rib portion 22.
Operation principle：Pass through the setting for cancelling stud so that the volume of shell 1 itself is reduced, upper flange 2 and shell 1 it
Between be fixedly connected by way of screw-thread fit, be in addition equipped with corresponding to the lower section of threaded hole 23 also at the inner wall of upper flange 2
Self-tapping screw slot 25, and pierced from threaded hole 23 by self-tapping screw, and slicing will be carried out to self-tapping screw slot 25, with
The mode of thread binding cooperates so that the combination between upper flange 2 and shell 1 is even closer.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
