Abstract
The utility model relates to an electric machine, particularly an energy-saving AC electric machine. The energy-saving AC electric machine is characterized in that a slot wedge used is made of metal material with favorable magnetic conducting performance. Because the metal magnetic-conducting slot wedge is used, not only the slot wedge has high intensity and is convenient to manufacture, but also the utility model has the advantages that the additional loss, the no-load current and the starting current of the electrical machine can be effectively reduced, the power factor and the efficiency of the electrical machine are improved, the temperature rise of the electrical machine is reduced and the service life of the electrical machine is extended.
Description
Invention field
The utility model relates to motor, especially a kind of energy-conservation alternating current machine.
Background technology
As everyone knows, the slot wedge material that uses on various alternating current machines at present is mao bamboon and epoxy resin bonded fiber.Because the influence of motor fluting is big in the air gap change of notch place motor, has therefore increased electric machine rotor surface loss and pulsation loss, the no-load current of motor also increases thereupon, has reduced the power factor of motor, makes temperature rise increase decrease in efficiency simultaneously.For addressing this problem, magnetic slot mud and magnetic slot-seal have obtained certain application.Yet magnetic slot mud uses inconvenience, the magnetic slot-seal processed complex, and these two kinds of slot wedge intensity all can not be satisfactory, therefore promotes unsatisfactory.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation alternating current machine, compares with common alternating current machine, and the complexity and the cost of manufacturing process are suitable, but the energy-saving effect of motor is good.
The purpose of this utility model is achieved in that a kind of energy-conservation alternating current machine, it is characterized in that, motor uses magnetic property good metal slot wedge.
Described metal slot wedge is made by the alloy of steel or steel, and the surface of slot wedge is through insulation processing, and the shape of slot wedge can be writing board shape, also can make circular shape, perhaps the inverted V-shaped shape.
Advantage of the present utility model is as follows:
Because, motor uses magnetic property good metal slot wedge, so, at motor notch place effective air gap contraction in length, the power factor of motor is improved, and the no-load current and the supplementary load loss of motor diminish, and then efficiency of motor improves, the starting current and the temperature rise of motor simultaneously also can reduce, and prolonged the useful life of motor.
Again because insulation processing has been carried out on the material surface of used magnetic property good metal slot wedge, is safe so use this metal magnetic conducting slot wedge for motor.Simultaneously, owing to be the metal magnetic conducting slot wedge, its intensity height, the facility of drawing materials, varied in thickness is flexible, makes rule become and is more prone to.
Also because, used diameter to be φ 1.0mm and following enamel insulated round copper wire thereof, the kelvin effect of winding is not obvious during machine operation, has further reduced the loss of electric machine, makes energy-saving effect more remarkable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.Among the figure: the 1-slot wedge; The 2-winding; The 3-stator core; The 4-slot liner.
Embodiment
Below in conjunction with accompanying drawing in detail execution mode of the present utility model is described in detail;
A kind of energy-conservation alternating current machine, its structure is identical with common alternating current machine.Slot wedge (1) is substituted common ring and is supported glass-cloth board or bamboo wedge by magnetic property good metal material.As specific embodiment, the material of slot wedge is steel Q-235A.A kind of manufacture method of slot wedge is: stamping-out-unhairing limit-moulding-surface insulation is handled.The concrete grammar that surface insulation is handled can be to be coated with one deck transformer oil on the slot wedge surface, perhaps floods the insulating varnish that motor windings is used, can also be with other surface insulation processing method.
Need to prove that the material that this specific embodiment uses is steel Q-235A.Slot wedge also can be the steel of other models, the perhaps metal material of other magnetic conductions when implementing the utility model.
The shape of this metal magnetic conducting slot wedge both can be tabular, also can be other shapes such as circular shape or inverted V-shaped shape.
The employed metal material thickness of slot wedge should be between 0.5-2.5mm.
