The utility model relates to a motor, particularly to a variable frequency motor. The variable frequency motor comprises a housing, a front end cap, a rear end cap, a rotating shaft, a plurality of stators, and a rotor, wherein the stators are fixed upon the inner wall of the housing; the rotor is fixedly connected to the rotating shaft; the stators are around the rotor; and the rear end cap of the motor is provided with a brake capable of stopping the rotation of the rotating shaft, with the brake being fixed to the rear end cap via a detachable bolt. The variable frequency motor further comprises a heat radiation apparatus for the heat radiation of the motor and the brake, with the heat radiation apparatus being fixed to the rear end cap via a connecting piece. The variable frequency motor features convenient braking and convenient mounting and dismounting of the brake. Moreover, the variable frequency motor can rapidly radiate the heat generated by the brake for braking motor and the heat generated by the motor, thereby prolonging the service lifetime of the motor.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of variable-frequency motor.
Background technology
Along with frequency converter increasingly extensive application in industrial control field; The use of variable-frequency motor is also increasingly extensive; Can only under specified situation, could stable operation compare with common electric machine, variable-frequency motor mechanical automation degree and production efficiency all improve a lot.Existing variable-frequency motor is when stopping operating; Can only rotor stopped operating through cutting off the electricity supply, inertia can not stop immediately but rotor tends to, if it is stopped immediately; Then need special brake apparatus; Braking inconvenience and production cost is higher, and can produce great amount of heat in the braking procedure, influences motor useful life.
The utility model content
Inconvenient, that production cost is high, braking the produces heat effects motor problem in useful life can only brake and brake to the utility model to existing variable-frequency motor when off-position, provide a kind of no matter switch on or powering-off state under all can easily rotor be stopped immediately and production cost is lower, the variable-frequency motor in prolongation motor useful life.
The purpose of the utility model realizes through following technical proposals: a kind of variable-frequency motor; Comprise housing, front end housing, rear end cap, rotating shaft, stator and rotor; Said stator is fixed on the inwall of housing, and rotor is fixedly connected in the rotating shaft, and track ring is around in peritrochanteric; The brake that rotating shaft is stopped operating is installed on the rear end cap of said motor; Said brake is fixed on the rear end cap through hinged bolt, and said variable-frequency motor also comprises the heat abstractor that motor and brake are dispelled the heat, and said heat abstractor is fixed on the rear end cap through connector.
Adopt this programme, the brake that rotating shaft is stopped operating is installed on the rear end cap of motor, like this brake and variable-frequency motor are made as one, therefore do not need special brake apparatus, can realize braking, reduced production cost variable-frequency motor.Because brake acts on the rotating shaft of variable-frequency motor, therefore no matter under the situation that energising still has a power failure, open brake and can realize braking motor.Simultaneously brake utilizes hinged bolt to be fixed on the rear end cap, can easily need be with its installation or removal.Through connector the heat abstractor that motor and brake are dispelled the heat is installed on the rear end cap, the heat that dispels the heat when heat that produces in the time of can be with the brake braking motor and machine operation distributes fast, prolongs the useful life of motor.
As preferably, said brake and heat abstractor outer periphery are equipped with fan housing, and said fan housing is fixed on the rear end cap.Fixing fan housing on the rear end cap can protect brake and heat abstractor not to be damaged, and makes the profile of motor also more attractive in appearance simultaneously.
As preferably, described heat abstractor is a blower fan.Blower fan and fan all have air-supply, heat dissipation capability, but fan is used for dispelling the heat, ventilation, and forced air supply then must be used blower fan.When brake is braked motor, can produce a large amount of heat, at this moment just need carry out the forced air supply heat radiation, heat is in time distributed, delay the aging of brake and motor motor internal.
As preferably, said brake is an electromagnetic brake.It is fast that electromagnetic brake has response speed, advantages of simple structure and simple.
In a word, it is convenient and the brake installation and removal are also more convenient to the utlity model has braking, and the heat that dispels the heat when heat that produces in the time of simultaneously can be with the brake braking motor and machine operation distributes fast, prolongs the useful life of motor.

Embodiment
A kind of variable-frequency motor; As shown in Figure 1, comprise housing 1, front end housing 2, rear end cap 3, rotating shaft 4, stator 5 and rotor 6, said stator 5 is fixed on the inwall of housing 1; Rotor 6 is fixedly connected in the rotating shaft 4; Stator 5 is surrounded on around the rotor 6, and the electromagnetic brake 7 that rotating shaft 4 is stopped operating is installed on the rear end cap 3 of said motor, and electromagnetic brake 7 is fixed on the rear end cap 3 through hinged bolt.Be provided with the blower fan 8 that motor and brake are dispelled the heat at the left end with rotating shaft 4 and electromagnetic brake 7 same level lines, said blower fan is fixed on the rear end cap 3 through connector 9.Electromagnetic brake 7 is equipped with fan housing 10 with blower fan 8 outer periphery, and fan housing 10 also is fixed on the rear end cap 3.
On the rear end cap 3 of motor, be installed with the electromagnetic brake 7 that rotating shaft 4 is stopped operating, like this brake 7 and variable-frequency motor be made as one, therefore do not need special brake apparatus, can realize braking, reduced production cost variable-frequency motor.Because electromagnetic brake 7 acts on the rotating shaft 4 of variable-frequency motor, therefore no matter under the situation that energising still has a power failure, open electromagnetic brake 7 and can realize braking motor.Simultaneously electromagnetic brake 7 utilizes hinged bolt to be fixed on the rear end cap 3, can easily need be with its installation or removal.Blower fan 8 through connector 9 independently be arranged at electromagnetic brake 7 around; The heat of generation in time distributes when braking with electromagnetic brake 7 countershafts 4 when rotating machine operation through the fan blade on the blower fan 8; Delay the aging of electromagnetic brake 7 and motor, prolong the useful life of motor.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition the equivalent form of value that those skilled in the art change or revise the installation site and the mounting means of brake falls within the application's appended claims institute restricted portion equally after the content of having read the utility model instruction.
