Description
Technical field
The utility model relates to a kind of wound rotor three-phase asynchronous motor, specifically is used for derrick crane, belongs to field of power equipment technology.
Background technology
Before the utility model was made, in prior art, the power set that use on the derrick crane normally adopted wound rotor three-phase asynchronous motor, and the cooling of threephase asynchronous has from fanning cold type and adding two kinds of structures of blower fan forced air cooling formula.Centrifugal fan from fan cold type structure is installed in the shaft extension end, the blower fan that adds blower fan forced air cooling formula is installed in non-shaft stretching end, the cooling air of these two kinds of structures all is to enter from non-shaft stretching end, through collector ring, enter motor stator cooling air channel cooling stator core, discharge from the air port of shaft extension end end cap then, make carbon brush contact the carbon dust that is produced with collector ring and accumulate on the motor winding, this type of cooling has reduced the useful life of wound rotor three-phase asynchronous motor.Because the tower machine needs serial-resistance speed-regulation with wound rotor three-phase asynchronous motor, fan the cold type wound rotor three-phase asynchronous motor certainly when low-speed running, cooling effect is very poor, causes motor temperature too high and burn motor.Though it is better to add the cooling effect of blower fan forced air cooling formula wound rotor three-phase asynchronous motor, add blower fan the tower machine is increased with wound rotor three-phase asynchronous motor overall volume and weight, this motor that is the high-altitude is used needs improved shortcoming.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of wound rotor three-phase asynchronous motor is provided, and makes carbon brush contact the carbon dust that is produced with collector ring and does not accumulate on the motor winding, can increase the service life; Fan can keep stable air quantity and blast, the good cooling results of motor with a constant rotating speed rotation; Can alleviate the motor overall weight, the motor volume is constant.
Main solution of the present utility model is achieved in that
The utility model mainly adopts inner cap, bearing assembly is installed on the shaft extension end of rotor successively, collector ring is installed on the rotor and is connected with the rotor winding, flange end cap links to each other with stator, the stator of again rotor being packed into, carbon brush is fixed on the housing and links to each other with stator, the brake end cap links to each other with housing, feature be fan by Bearing Installation on the fan flange, the fan flange is fastened on the brake end cap, fan can rotate freely, synchronizing wheel is installed on fan, micromachine is connected with motor flange, and synchronous pulley is installed on the motor shaft of micromachine, and motor flange is connected with the brake end cap, synchronous belt is fixed on the brake end cap, and cover cap is covered.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because fan is installed in non-shaft stretching end, cooling air enters the motor stator cooling air channel from the shaft extension end, the cooling stator core, through collector ring, and carbon brush is contacted the carbon dust that is produced discharge with collector ring from air outlet, make carbon brush contact the carbon dust that is produced with collector ring and do not accumulate on the motor winding, can prolong the useful life of wound rotor three-phase asynchronous motor, the carbon dust that has solved fan inner-cooled wound rotor three-phase asynchronous motor accumulates the technical barrier on the motor winding; Because the rotating speed of fan is determined that by micromachine with the rotor irrelevant to rotation of wound rotor three-phase asynchronous motor, fan can keep stable air quantity and blast with a constant rotating speed rotation, makes the good cooling results of motor; The cooling effect that adds the blower fan forced air cooling is arranged, and the motor that adds blower fan forced air cooling formula structure has compact conformation, alleviates the characteristics of motor overall weight; Improve a lot, but the motor volume is constant, the characteristics that weight does not increase from the cooling effect of fanning the motor of cold type structure.
