Abstract
The utility model relates to a variable frequency motor with a fan in the front, comprising a motor housing, and a motor shaft, a stator and a rotor mounted in the motor housing. The variable frequency motor is characterized in that the fan is mounted in the front end of the motor shaft via a flat key; an encoder rack is fixed in the rear end of the motor housing, wherein an encoder is mounted on the encoder rack, and a shaft of the encoder is connected with the rear end of the motor shaft via a shaft coupling; a fan housing is arranged outside the fan; an encoder cover is arranged outside the encoder; and a shaft-used block ring is arranged in the end portion of the fan. The variable frequency motor with the fan in the front has the advantages that the fan and the encoder of the variable frequency fan are respectively mounted in the front and rear end of the motor shaft, and do not influence each other; the fan is arranged in the front end, cooling effect of the motor is better, and the encoder is installed conveniently and firmly and not easy to damage; and the special encoder cover is mounted outside the encoder, so as to prevent the encoder from damages or influences of dust, water and oil.
Description
Technical field
The utility model relates to the preposition variable-frequency motor of a kind of fan, and especially a kind of electric motor fan and encoder are installed on respectively the structure at motor shaft two ends, belong to the electric machine structure technical field.
Background technology
Along with the develop rapidly of converter technique, the application of variable-frequency motor is increasingly extensive.In order to control more accurately the rotating speed of variable-frequency motor, in the situation that the encoder model is certain, encoder be mounted for key.
At present, when motor is installed, normally adopt the afterbody that electric motor fan and encoder is installed on jointly motor, and such mounting means has just had influence on the installation of encoder, makes encoder not have the fixed position.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of fan preposition variable-frequency motor, and the fan of this variable-frequency motor and encoder are installed on respectively the two ends of motor shaft, makes fan, encoder cooperate tightr with motor.
The technical scheme that provides according to the utility model, the variable-frequency motor that a kind of fan is preposition, comprise electric machine casing, mounted motor axle, stator and rotor in electric machine casing, feature is: the front end at described motor shaft passes through the flat key provided with fan, at the rear end of electric machine casing regular coding device frame, at the encoder frame encoder is set, the axle of encoder is connected by shaft coupling with the rear end of motor shaft.
At described fan outer setting fan housing.
At described encoder outer setting encoder cover.
End at described fan arranges shaft block ring.
The beneficial effects of the utility model are: the fan of variable-frequency motor described in the utility model and encoder are installed on respectively the front and back end of motor shaft, are independent of each other; Fan is preposition, and the cooling effect of motor is better, and encoder is easy for installation firmly, not fragile; And, special encoder cover is housed outside encoder, prevent that dust, water, oil from damaging encoder or affecting encoder work.
