Technical field
The present invention relates to brshless DC motor field, more particularly to a kind of self-locking structure of miniature brushless direct-current motor.
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：Receive the startup, stopping, brake signal of 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, the closing component structure between housing and upper flange usually sets a long threaded rod 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.
The content of the invention
It is an object of the invention to provide a kind of miniature brushless direct-current motors to have solved the problems, such as in background technology.
A kind of self-locking structure of miniature brushless direct-current motor, including housing and upper flange, the housing is cylindric, housing
Inner wall for smooth surface, the upper end of inner walls has internal thread；The lower end of the upper flange has matches somebody with somebody 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 set 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 being used to appear iron core for tool in the rib portion.
Beneficial effects of the present invention are：By the setting for cancelling stud so that the volume of shell itself is reduced, upper flange and
It is fixedly connected between housing by way of thread fitting, in addition also corresponds at the inner wall of upper flange below threaded hole and set
There is self-tapping screw slot, and pierced by self-tapping screw at threaded hole, and slicing will be carried out to self-tapping screw slot, with screw thread
With reference to mode cooperate so that the combination between upper flange and housing is even closer.
