Abstract
The utility model relates to an air-cooled series excited DC motor, which comprises a casing, a rotating shaft, a rotor, a stator, a carbon brush, a commutator, a front end cover and a rear end cover, and is characterized by further comprising a fan, wherein the casing on the upper end of the commutator is provided with an air inlet, an air outlet is arranged in the rear end cover, and the fan is mounted on the outer side of the casing and is communicated with the air inlet. The air-cooled series excited DC motor has the advantage of effectively discharging heat and cooling the interior of the casing.
Description
Technical field
The utility model relates to a kind of DC motor, relates in particular to a kind of air-cooled series excitation DC motor.
Background technology
Existing series excitation DC motor is mainly as the motor of slush pump, rotating disk and the winch in oil field, and it comprises casing, rotating shaft, rotor, stator, carbon brush, commutator, front end housing and rear end cap; Because this series excitation DC motor can produce very large heat in use, and be a relatively space of sealing in casing, if can not timely casing inside be lowered the temperature, break down while easily causing series excitation DC motor to use.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide a kind of can carry out to casing inside the air-cooled series excitation DC motor of effective heat extraction cooling.
Technology contents of the present utility model: a kind of air-cooled series excitation DC motor, it comprises casing, rotating shaft, rotor, stator, carbon brush, commutator, front end housing and rear end cap; It is characterized in that it also comprises blower fan, be provided with an air inlet on the casing of commutator upper end, be provided with air outlet on rear end cap, assembling is in the casing outside and be communicated with air inlet.
The advantage that the utility model compared with prior art had is: the utility model is lowered the temperature to casing inside by blower fan, thereby makes to guarantee the normal operation of series excitation DC motor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in Figure 1, a kind of air-cooled series excitation DC motor, it comprises casing 1, rotating shaft 2, rotor 3, stator 4, carbon brush 5, commutator 6, front end housing 7 and rear end cap 8; It is characterized in that it also comprises blower fan 9, be provided with an air inlet 1.1 on the casing 1 of commutator 6 upper ends, be provided with air outlet 8.1 on rear end cap 8, blower fan 9 is arranged on casing 1 outside and is communicated with air inlet 1.1.
