Abstract
The utility model relates to a series excited DC motor for oil fields, 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 in that the front end of the commutator is wrapped with a layer of protective belt. The series excited DC motor for oil fields has the advantage of improving arc resistance capability of the commutator.
Description
Technical field
The utility model relates to a kind of DC motor, relates in particular to a kind of oil field series excitation DC motor.
Background technology
Existing oil field is the motor mainly as slush pump, rotating disk and the winch in oil field with series excitation DC motor, 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 electric arc in use, ring fire is easy to the commutator front end is caused damage, and has shortened thus the useful life of oil field use series excitation DC motor.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide a kind of oil field series excitation DC motor that can improve the anti-electric arc ability of commutator.
Technology contents of the present utility model: a kind of oil field 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: at the commutator front end, be surrounded with one deck boundary belt.
The advantage that the utility model compared with prior art had is: the utility model is the anti-electric arc ability of commutator and the moistureproof ability that can improve by boundary belt, thereby has improved the useful life of oil field use series excitation DC motor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of oil field 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: at commutator 6 front ends, be surrounded with one deck boundary belt 9.
