Magnetic dead electricity braking motor or braking asynchronous motor.But the brake gear in current brake motor is all placed in casing, and outside is used
One protective cover is covered, and this motor volume is big, and moisture effect is poor, and because protective cover is relatively thin, soundproof effect is poor, so stopping
Che Shihui produces larger noise, easily produces hearing impairment to operating personnel and causes noise pollution to surrounding environment.
Utility model content
In order to overcome drawbacks described above, the utility model provides a kind of brake built-in electric machine, and the motor can be solved
There is the technical problem for easily producing loud noise pollution in use in existing motor.
The utility model is to solve the technical scheme that its technical problem is used：
One kind brake built-in electric machine, including motor body and braking device, the motor body include support,
Casing, rotating shaft, stator and the rotor being fixed in rotating shaft, the stator and rotor are located at casing Inner Front End, the tail of the rotating shaft
End and braking device are located at rear end in casing, and the braking device can unclamp and embrace the tail end of rotating shaft, described
The end of casing is provided with rear end cap.
Preferably, the mechanism that the braking device can unclamp and embrace the tail end of rotating shaft is, also including an electromagnetism
Body, the braking device includes pedestal and is sheathed on the brake disc of rotating shaft tail end, and the electromagnet can control brake disc
Separate and close.
Preferably, the braking device has the cooling-part for lowering the temperature.
Preferably, the cooling-part is fan.
The beneficial effects of the utility model are：The utility model includes motor body and braking device, the motor
Body has casing, stator, rotating shaft and the rotor being fixed in rotating shaft, and not only stator, rotor are located at motor body casing internal,
And the tail end and braking device of rotating shaft are also in the casing because casing typically all with thicker grey cast-iron or other
Aluminum alloy material, soundproof effect is good, therefore when braking device works, will not produce larger noise, is conducive to operation
The physical and mental health of personnel.Simultaneously as brake gear is installed in casing, moisture effect is good, will not occur to cause due to making moist
The situation that brake cannot work, and compact conformation, save space, are also prevented from brake gear and clash into what is caused by other objects
Damage.

In figure：1- motor bodies, 11- casings, 12- rotating shafts, 13- supports, 14- rear end caps, 15- terminal boxes.
Specific embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the utility model embodiment is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of brake built-in electric machine, including motor body 1 and braking device, it is described
Motor body 1 includes support 13, casing 11, rotating shaft 12, stator and the rotor being fixed in rotating shaft, and the stator and rotor are located at
Casing Inner Front End, the tail end and braking device of the rotating shaft are located at rear end in casing 11, and the braking device can
The tail end of rotating shaft is unclamped and embraces, the end of the casing 11 is provided with rear end cap 14.The utility model includes motor body 1 and stops
Car brake apparatus, the motor body 1 has casing, stator, rotating shaft and the rotor being fixed in rotating shaft, the stator, rotor
Positioned at motor body casing internal, the tail end and braking device of the rotating shaft are also located in casing, positioned at the rear end of casing
Portion, rear end cap 14 forms closing space with casing 11.Because casing typically all uses thicker grey cast-iron or other aluminium alloy materials
Matter, soundproof effect is good, therefore when braking device works, will not produce larger noise, is conducive to the body of operating personnel
Heart health, simultaneously as brake gear is installed in casing, moisture effect is good, will not occur to cause due to making moist the brake cannot
The situation of work, and compact conformation, save space, be also prevented from brake gear and the damage for causing is clashed into by other objects.Fig. 1
With shown in Fig. 2 only as one embodiment of the present utility model, the utility model be also applied for anodontia motor or other
Any kind of motor that brake gear can be placed in casing.The braking device has the cooling end for lowering the temperature
Part.The cooling-part is fan.Fan is used as cooling-part, when motor needs frequently to be operated, will not be produced
Heat is excessive and cause temperature to raise and cause the shortcoming of motor damages.
Wherein, the mechanism that the braking device can unclamp and embrace the tail end of rotating shaft is, also including an electromagnet,
The braking device includes pedestal and is sheathed on the brake disc of rotating shaft tail end, and the electromagnet can control brake disc to separate
With close.So that the power supply of the motor and braking device is synchronous as an example, the power supply of the braking device is from electricity
The lower end of terminal box 15 of machine is drawn, and during energization, electromagnet produces electromagnetic force to cause that brake disc is separated, i.e., brake disc unclamps rotating shaft
12, now motor being capable of normal rotation；During power-off, due to losing electromagnetic force, spring causes that brake disc closes, i.e. brake disc
Hold rotating shaft 12 tightly so that motor can in a short period of time stop inertia rotation, play the function of brake.Some brake gears
With the running just conversely, when being powered, electromagnet produces electromagnetic force to cause that brake disc closes, i.e., brake disc holds rotating shaft tightly
12, motor stalls；During power-off, brake disc is separate, and motor being capable of normal rotation.Certain the utility model is equally applicable to
The power supply of motor and braking device is asynchronous motor.
The course of work of the present utility model is：When motor is in energization rotary state, electromagnet generation electromagnetic force makes
The brake disc obtained in braking device is separated, i.e., brake disc unclamps rotating shaft, and now motor being capable of normal rotation；When needs are stopped
Che Shi, then carry out power down process, and because electromagnet loses electromagnetic force, spring causes that the brake disc in braking device is closed
On, i.e., brake disc holds rotating shaft tightly so that motor can in a short period of time stop inertia rotation, play the function of brake, this
Working method is planted for the power supply of motor and braking device is synchronous.Also electricity can be worked as by the way of line asynchronous
When motivation is powered, brake gear power-off, and during electric motor circuit breaking, brake gear is powered.
It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility,
Various modifications and improvements can be made, these belong to protection domain of the present utility model.Therefore, the utility model patent
Protection domain should be determined by the appended claims.
