Description
Technical field
The utility model relates to design of electrical motor technical field, especially relate to a kind of strengthen the stable connection of rotor, with the motor of bracket.
Background technology
Along with the development of power electronic technology, servomotor is widely used in all trades and professions, its operation principle the signal of telecommunication received is converted to angular displacement on servo motor shaft or angular speed exports, control easily, small in volume, power output and torque greatly, facilitate speed governing, are used widely in recent years.
Existing electric machine structure generally comprises motor stator and is positioned at the rotor of motor stator, and rotor produces magnetic field by rotating relative to motor stator.But current existing this electric machine structure, when rotor high-speed motion time, easily occurs that position offsets, and even occurs phenomenons such as coming off time serious, affect motor and motor thereof connect shop equipment and can not run well.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of motor with bracket, by increasing by an analog bracket, to improve the rotational stability of rotor further.
For achieving the above object, the utility model proposes following technical scheme: a kind of motor with bracket, comprise end cap, motor stator and rotor, described end cap is arranged on one end of described motor stator and rotor, described motor stator comprises stator core and is wound on the stator coil on described stator core, described rotor is positioned at motor stator, and it comprises the rotating shaft being fixed with magnet on the surface, fixedly mounts an electric machine support between described rotating shaft and end cap.
Further, also comprise motor housing, between described motor housing and described stator coil, be formed with epoxy packages layer by perfusion.
Further, described stator coil outer filling is formed with BMC encapsulated layer.
Preferably, described rotating shaft is rotatably installed in the middle part of described electric machine support by the installing hole on described electric machine support, and its top is stretched out outside described end cap.
Preferably, described rotating shaft is rotated by motor bearings and is installed in the installing hole of described electric machine support.
Further, the installing hole of described electric machine support is also provided with lock screw.
The beneficial effects of the utility model are: the installation steadiness further increasing electronics rotor, avoid the phenomenons such as its displacement occurred in high speed rotating process, ensure that normal operation and the fail safe of motor.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical scheme of the utility model embodiment.
Shown in composition graphs 1 and Fig. 2, a kind of motor with bracket that the utility model discloses, comprise end cap 10, motor stator (not shown) and rotor 20, end cap 10 is arranged on same one end of motor stator and rotor 20, rotor 20 is arranged in stator, and rotates generation magnetic field.
Motor stator comprises stator core and stator coil, and stator coil winding is on the skeleton of stator core.The magnet (not shown) that rotor 20 comprises rotating shaft 21 and is fixed on rotating shaft 21 surface, one end of rotating shaft 21 is stretched out outside end cap 10.
In order to improve the rotational stability of rotor, the utility model is in the inner side of end cap 10 and increase installation one electric machine support 30 between rotating shaft 21 and end cap 10, thus in the process of rotating at rotor 20, carries out location to a certain degree and restriction to it.The middle part of electric machine support 30 arranges one for installing the installing hole 31 of rotating shaft 21, and rotating shaft 21 is rotatably installed in this installing hole 31 by a motor bearings 40.
Preferably, the installing hole 31 of electric machine support 30 is also arranged a spacing ring 50, spacing ring 50 is fixed on the installing hole 31 of electric machine support 30 by lock screw 51.
Further, in order to improve insulating properties and the resistance to pressure of stator coil, generally to encapsulate stator coil.The utility model provides two kinds but is not limited to this two kinds of encapsulating structures, and one is that motor also comprises motor housing (not shown), between motor housing and stator coil, form epoxy packages layer (not shown) by perfusion; Another kind omits motor housing, directly forms BMC encapsulated layer (not shown) at stator coil outer filling.
The utility model adds an electric machine support on existing electric machine structure, improves the stability of rotor turns, ensure that the normal operation of motor and improves its coefficient of safety run.
Technology contents of the present utility model and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present utility model and announcement; therefore; the utility model protection range should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
