Abstract
A high efficiency and energy-saving motor used in a pumping unit is provided, which comprises a seat, a fan, an end cover, a stator core with windings, a rotor core and a fan hood, and is characterized in that: a rotor winding on the rotor core consists of a rotor upper winding and a rotor lower winding, which are short-circuit connected into a star shape or a delta shape. The utility model has the advantages of simple structure, convenient maintenance, high efficiency, big torque after being started, good energy-saving effect, etc. Being capable of being operated for years under severe outdoor condition, the utility model is particularly applicable to oil fields, and can also be used under full load for starting other appliances, such as a draught fan, a pump, etc.
Description
(1) technical field
The utility model relates to a kind of motor.
(2) technical background
A large amount of oil pumpers is being used in oil fields such as China's grand celebration, Panjin, triumph, Xinjiang, is that it is supporting at present
The series motor, the lower and oil pumper of its starting torque needs very high starting torque, for the oil pumper that makes the oil field rotates, often adopts high-power grade motor.Ubiquity low load with strong power phenomenon has been wasted a large amount of energy like this.
(3) summary of the invention
For addressing the above problem, the utility model provides a kind of high-efficient energy-saving motor for oil pumping machine.
The technical scheme that adopts
High-efficient energy-saving motor for oil pumping machine comprises support, end cap, band winding stator core, rotor, fan guard, fan.Its major technique feature is that motor rotor is a winding-type, is wound with rotor upper strata winding and rotor lower floor winding on the rotor core, and rotor upper strata winding becomes at the end short circuit with rotor lower floor winding
Shape, but also short circuit becomes △ shape.
The utility model is subseries of threephase asynchronous, is to be the supporting a kind of novel motor of oil pumper specially, and structurally rotor adopts two layer winding and becomes at the end short circuit
Type or △ type adopt this structure, make that the motor starting electric current is little, and starting torque is big, and starting is level and smooth; During normal the operation, efficient is higher, power factor is high, save the energy, reduces the pressure drop of power supply network, the utlity model has higher mechanical property, the rotating speed of motor can change with the variation of pump load, thereby has improved oil pumping stalk force-bearing situation, has prolonged the useful life of equipment.Facts have proved, the motor of the utility model 15kw can replace existing used for oil extractor 22kw motor, 22kw can replace 37kw, 30kw can replace 45kw, 37kw can replace 55kw or 75kw, and promptly alternative high two power grades series motor has good energy-saving effect, can save energy 10%-17%, the utlity model has simple in structure, easy to maintenance, the efficient height, starting torque is big, advantages such as good energy-conserving effect, well operation all the year round under the mal-condition in the open air is particularly suitable for the oil field and uses, also can be used for fully loaded other place that starts of requirement, as blower fan, water pump etc.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.Fig. 2 is the structural representation of the utility model rotor winding.
(5) embodiment
High-efficient energy-saving motor for oil pumping machine, comprise support 1, fan 2, end cap 3, band winding stator core 4, rotor core 5, fan guard 6, its structural feature is to put on the rotor core 5 around the home to be made up of rotor upper strata winding 7 and rotor lower floor winding 8, and rotor upper strata winding 7 becomes with the end of rotor lower floor winding 8
Shape connects.
Claims (2)
1, high-efficient energy-saving motor for oil pumping machine, comprise support (1), fan (2), end cap (3), band winding stator core (4), rotor core (5), fan guard (6), it is characterized in that the rotor winding on the rotor core (5) is made up of rotor upper strata winding (7) and rotor lower floor winding (8), rotor upper strata winding (7) becomes at the end short circuit with rotor lower floor winding (8)
Shape or △ type.
2, high-efficient energy-saving motor for oil pumping machine according to claim 1, it is characterized in that rotor upper strata winding (7) and rotor lower floor winding (8) make respectively in the end winding short circuit become △ shape or
Shape.
