Abstract
The utility model discloses a stator skewed slot structure of a shielding electric pump, and is characterized in that skewed slots (2) are arranged on an inner surface of an annular stator (1) of the shielding electric pump, the included angle between the skewed slots (2) and the central axis of the stator (1) is 5 to 15 degrees, and a plurality of skewed slots are evenly distributed on the circumference. The stator skewed slot structure of the shielding electric pump is simple in structure, ingenious in design, and reasonable in layout, can reduce electromagnetic vibration and noise, and improve operational reliability and safety of the pump.
Description
Technical field
The utility model relates to a kind of shielded electric pump internal structure, particularly a kind of shielded electric pump skewed stator slot structure.
Background technology
The motor that shielded electric pump is used adopts threephase asynchronous more, and threephase asynchronous on the make, offer skewed slot (being rotor chute) on cast-aluminum rotor and copper casting rotor more, after being provided with skewed slot, can weaken the magnetic wave electromotive force that harmony wave produces, thereby reach the caused additional torque in reduced harmonic magnetic field, reduce electric and magnetic oscillation and noise, make the operation that pump can be more reliable and safe in working site.But if the rotor of powerful asynchronous motor adopts method processing and the making of lower copper bar, just the more difficult processing of rotor chute does not generally all have skewed slot on therefore hard winding.So need now a kind of Novel electric pump configuration that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, can reduce the shielded electric pump skewed stator slot structure of electric and magnetic oscillation and noise, raising pump operation reliability and fail safe.
Technical solution of the present utility model is: a kind of shielded electric pump skewed stator slot structure is characterized in that: on shielded electric pump stator 1 inner surface of ring-type, offer skewed slot 2, the angle between skewed slot 2 and stator 1 axis is the 5-15 degree.
Described skewed slot 2 is a plurality of, and is uniformly distributed on circumference.
The utility model compared with the existing technology, has following advantage:
The shielded electric pump skewed stator slot structure of this kind of version, it is simple in structure, designs ingenious.Traditional threephase asynchronous machine need to be offered skewed slot on rotor, thereby realizes the purpose of the magnetic wave electromotive force that the weakening harmony wave produces, but, in the motor of some type, can't on rotor, offer skewed slot, therefore can't address the above problem.The utility model has creatively been offered skewed slot on stator, both met need of work, convenient processing again, manufacture craft is simple, improvement cost is cheap, therefore this skewed stator slot structure has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
the accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment stator.
Fig. 2 be in Fig. 1 A-A to view.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1 and Figure 2: a kind of shielded electric pump skewed stator slot structure, shielded electric pump stator 1 ringwise, at it on annular inner surface, offer a plurality of skewed slots 2, and these skewed slots are uniformly distributed on circumference, its quantity can be arranged according to actual needs, has an angle between the axis of skewed slot 2 and stator 1 simultaneously, and the scope of this angle is the 5-15 degree.
Claims (2)
1. a shielded electric pump skewed stator slot structure, it is characterized in that: on shielded electric pump stator (1) inner surface of ring-type, offer skewed slot (2), the angle between skewed slot (2) and stator (1) axis is the 5-15 degree.
2. shielded electric pump skewed stator slot structure according to claim 1 is characterized in that: described skewed slot (2) is for a plurality of, and is uniformly distributed on circumference.
