Abstract

The utility model discloses an external rotor motor. The motor comprises a rotor, a stator and a rotating shaft. The rotating shaft is installed at a center of the rotor and is cooperated with a stator through bearings installed on two ends of a stator center hole. The rotating shaft and the rotor are cast into one body. A stator core portion is provided with a heat dissipation tube which carries out heat dissipation through using a heat dissipation medium. Two ends of the heat dissipation tube lead out a stator external portion which is connected with the external heat dissipation tube. According to the motor of the utility model, the rotating shaft and the rotor are cast into one body; the structure is compact; balance and stability of motor running are increased; the heat dissipation tube is arranged on the stator; the heat dissipation medium is used to take away heat generated by a winding in the stator so that motor efficiency is increased.

Description

External rotor electric machine
Technical field
The utility model relates to a kind of motor, especially a kind of external rotor electric machine.
Background technology
Existing motor product, by the arrangement of stator and rotor, can be divided into inner rotor type motor and external-rotor motor.Inner rotor type motor rotor is rotatably installed in stator interior, and external-rotor motor rotor is rotatably installed in stator outside.In a lot of application scenarios, external rotor electric machine, because its cooling performance is undesirable, causes motor performance to be affected, and efficiency can not maximize.
Utility model content
The utility model technical issues that need to address are to provide a kind of good cooling results, the external rotor electric machine that electric efficiency is high.
For addressing the above problem, technical solution adopted in the utility model is: a kind of external rotor electric machine, comprise rotor, stator and rotating shaft, its shaft is arranged on rotor center, and coordinate with stator by the bearing that is arranged on two ends, stator center hole, described rotating shaft and rotor are integrated casting, are provided with the radiating tube that utilizes heat eliminating medium heat radiation at stator core, motor stator outside is drawn at the two ends of radiating tube, is connected with external cooling pipeline.
The snakelike stator core that is distributed on of described radiating tube.
The beneficial effect that adopts technique scheme to produce is: the utility model rotating shaft and rotor are integrated casting, compact conformation, balance and the stability of motor rotation have been strengthened, radiating tube is set on stator, the heat that utilizes heat eliminating medium that winding in stator is produced is taken away, and improves the efficiency of motor.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1, stator, 2, rotor, 3, radiating tube, 4, rotating shaft.
Embodiment
Below in conjunction with accompanying drawing, utility model is described in further detail: as shown in Figure 1, this Novel external rotor motor comprises rotor 2, stator 1 and rotating shaft 4, its shaft 4 is arranged on rotor center, and be cast into one with rotor, it coordinates with stator by the bearing that is arranged on two ends, stator center hole, make its concentricity better, stability after having assembled is better, balance and the stability of motor rotation have been strengthened, in order to improve the performance of motor, increase work efficiency, the core setting of stator, utilize heat eliminating medium (water, wet goods) heat radiation radiating tube, motor stator outside is drawn at the two ends of radiating tube, be connected with external cooling pipeline and increase cooling effect, to increase work efficiency.Described radiating tube is connected to form by many single tubes and elbow, is distributed on stator core, finally forms serpentine coil, and all draw from one end of stator at its two ends.
