Abstract
A single-phase motor (10) particularly for submersed pumps, characterized in that it comprises an annular capacitor (14) interposed between the pump coupling head (15) and the stator winding pack (12).
Description
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a kind of single-phase motor that is used for immersible pump.
Background technology
Common employed motor is a kind of monopole asynchronous motor that requires two stator winding that 90 ° of phase differences are arranged to start.
The power supply place that a kind of method that is used for realizing two winding phase shifts is a winding therein inserts a permanent electric capacity that connects.
Such motor is to be roughly main body cylindrical and that comprise the stator winding group by one to constitute, and this stator winding group is ordered about the rotor rotation that head stretches out in pump coupling head place.
This motor and pump unit equipment are used for reaching deeply the well of hundreds of rice.
If electric capacity is integrated in the control panel of motor, just the line of electric capacity need be linked motor, thereby will use the cable of three lead-in wires to add ground wire.
In order to address this problem, a possible solution is exactly that motor is equipped with an internal capacitance, and it is provided with connection in described motor interior, and is drawn out to the motor outside with the cable of a two-conductor line and band earth connection.
This solution can be directly connected on the mains supply motor.
In some existing solutions, the hydrostatic column of motor is in the bottom, and just relative with the coupling head of pump part is provided with a compartment that is used for holding electric capacity.
Although electric capacity is integrated in the motor body can saves control panel, this solution is defectiveness also.
As described, electric capacity is actually the bottom that is placed on motor, just with stator winding group and the common relative end of electrical connector of drawing from the pump coupling head.
Therefore the service cable of electric capacity must carry out appropriate insulation and be adjacent to pass whole motor with the stator winding group, and has increased the complexity on the motor geometry; Need perhaps to be provided with that one one side has power connection, opposite side has the suitable winding that electric capacity connects, even but to produce this winding automatically be possible, this also can make it become complicated.
Summary of the invention
The objective of the invention is to solve or alleviate significantly the existing problem of single-phase motor that traditional immersible pump is used.
An important purpose provides a kind of motor, and it need not to insert a plate that comprises electric capacity just can be directly connected in circuit, and has reduced the quantity of lead.
Another object of the present invention is to eliminate the electrical wiring that passes at the stator winding place, also need not the winding that provides special.
It is more clear that this target and the purpose of these and other will become hereinafter, and they are to comprise that by a kind of being characterised in that one places the single-phase motor that is used for immersible pump of the annular capacitor between pump coupling head and the stator winding group to realize.
Brief description of drawings
From description, become more clear in the other features and advantages of the present invention meeting to a preferable but non-exclusive embodiment of the present invention.This embodiment carries out illustrated in indefiniteness example mode.In these accompanying drawings:
Fig. 1 is a sectional arrangement drawing according to motor of the present invention;
Fig. 2 is the stereogram of the electric capacity of a use in motor shown in Figure 1;
Fig. 3 is the drawing in side sectional elevation of electric capacity shown in Figure 2.
Embodiment
Referring to accompanying drawing, the pump motor that is used to dive under water according to the present invention generally is marked with by reference number 10.
Motor 10 is monopole asynchronous motors, and it is contained in one and is roughly in the columniform box main body 11.
One group of stator winding 12 is housed in the main body 11, and in these stator winding, comprises a rotor 13.
Stator winding group 12 is made of the stator winding of two separation.One in these two stator winding is connected on the power supply, and another links to each other with an electric capacity, and this electric capacity is generally identified by reference number 14.
Electric capacity 14 is one and places the annular capacitor between stator winding group 12 and the pump coupling head 15.
In fact, coupling head 15 is provided with the screw element 16 that is used for fixing pump, and it is not represented in the drawings, but it is any well-known type.And the head 17 of rotor 13 stretches out from coupling head 15.
Head 17 is connected on the pump shaft.
Electric capacity 14 advantageously is a thin-film capacitor, is made of the longitudinal tensile strain plate 18 around a tubular support 19, and is contained in the box spare 20 of a tubulose.This box spare 20 has been filled resin and has been inserted for plate 18 in the end.
Box spare 20 is provided with inside and outside cannelure 21 at tubular inner wall 22 places.
Particularly, inner cannelure 21a is used for allowing the connection lead 23 of plate 18 pass, and outside cannelure 21b allows the power line of stator winding group 12 pass.
At last, tubulose box spare 20 usefulness resins 24 fill up so that plate 18 insulation.
In fact can find that the present invention has realized target and the purpose wanted.
Especially, clearly be that the special shape of electric capacity can be placed on the favourable position described electric capacity.
Disclosed content is incorporated here among the disclosures in Italian patent application PD2000A000085 of priority that the application requires, for your guidance.
