Description

Permanent-magnet synchronous submersible motor
Technical field
The utility model belongs to technical field of motors, relates to a kind of permanent-magnet synchronous submersible motor.
Background technology
Motor is very extensive in all trades and professions application, and the generating total amount of electrical consumption world 60-70%, the efficiency therefore improving motor is the energy-conserving and environment-protective problem of entire society, and current people devise various high efficiency motor.Existing people upgrade in the manufacturing process of motor and the selection of material, do not obtain the solution of essence from structure, and the efficiency of motor still needs to improve.
Notification number is the Chinese patent of CN202872593U, disclose a kind of three-phase induction asynchronous machine, comprise casing, be equipped with rotating shaft in described casing, in described rotating shaft, circumference is fixed with rotor, is arranged with the stator fixing with casing circumference outside described rotor, it is characterized in that, described rotor is formed by silicon steel plate stacking and rotor is embedded is connected to mouse cage, and described stator is also formed by silicon steel plate stacking, and described stator internal fixtion has three phase sine distributed winding.This motor power saving rate is good, reduces use cost, is huge to the saving of power consumption, is very favorable to the saving of resource, the protection of environment and improvement, and this motor manufacturing is convenient in addition, low cost of manufacture.
But motor temperature directly decides the performance index of complete machine, temperature is too high will affect service life and the efficiency of motor.No matter which kind of motor must consider temperature index and how heat dissipation problem in design of electrical motor process.The motor of current various cooling structure is numerous, and its cooling structure adopts recirculated water or oil cooling but mostly, and this type of cooling can only cool the part-structure of motor, and cannot reach comprehensive cooling, there is the drawback that cooling effect is poor.
Therefore, according to the problems referred to above and in conjunction with prior art, need to propose one more reasonably motor.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of permanent-magnet synchronous submersible motor, has energy-efficient feature.
For achieving the above object, the utility model provides following technical scheme: a kind of permanent-magnet synchronous submersible motor, comprises casing, and described casing comprises housing, front end housing and rear end cap; Be provided with stator, rotor and rotating shaft in described casing, described casing be provided with front end housing and rear end cap; Described rotor is embedded with multipole permanent magnet and mouse cage; Described front end housing and rear end cap are fixed by welding on housing; Described rotating shaft two ends are fixed on casing by bearing, and wherein one end penetrates described front end housing; Insulation cold oil is filled in described casing; Forward end seal circle is provided with between described front end housing and rotating shaft; Air gap between described stators and rotators is 1.4 ~ 2.3mm.
Compared with prior art, the utility model has the advantages that:
Casing internal fills insulation cold oil, can cool by the assembly (comprising stator, rotor, winding etc.) all to motor internal, and relative to adopting the circulating type of cooling at present, cooling effect significantly promotes; Be provided with this front and back ends sealing ring accordingly at the front and back ends of motor simultaneously, prevent insulation cold oil from oozing out; Owing to not containing air in insulation cold oil, also stop the problems such as motor internal assembly gets rusty, extended the useful life of motor; In addition, due to sound insulate propagate in cold oil time, its Oscillation Amplitude can be suppressed, and therefore, insulation cold oil also serves the effect reducing motor noise; In addition, owing to having filled insulation cold oil in casing, the change of magnetic flux can be caused, and the size of magnetic flux is decided by the size of gaps between rotor and stator, therefore, consider and the utility model relates to a kind of synchronous machine, and experimentally gained, the size of air gap is set in 1.4 ~ 2.3mm, to ensure the efficient object of machine operation.
Further, the spacing of described permanent magnet and stator is 13.2 ~ 15.6mm.
Further, described insulation cold oil is tung oil or silicone oil or linseed oil or transformer oil.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the utility model embodiment.
Accompanying drawing marks: 1, housing, and 2, front end housing, 3, rear end cap, 4, stator, 5, rotor, 6, rotating shaft, 7, insulation cold oil, 8, forward end seal circle, 9, mouse cage, 10, permanent magnet.
Embodiment
With reference to Fig. 1, the utility model embodiment is described further.
A kind of permanent-magnet synchronous submersible motor, comprise casing, casing comprises housing 1, front end housing 2 and rear end cap 3; Be provided with stator 4, rotor 5 and rotating shaft 6 in casing, casing be provided with front end housing 2 and rear end cap 3; Rotor 5 is embedded with multipole permanent magnet 10 and mouse cage 9; Front end housing 2 and rear end cap 3 are fixed by welding on housing 1; Rotating shaft 6 two ends are fixed on casing by bearing, and wherein one end penetrates front end housing 2; Insulation cold oil 7 is filled in casing; Forward end seal circle 8 is provided with between front end housing 2 and rotating shaft 6; Air gap between stator 4 and rotor 5 is 1.4 ~ 2.3mm.
Compared with prior art, the utility model has the advantages that:
Casing internal fills insulation cold oil 7, can cool by the assembly (comprising stator 4, rotor 5, winding etc.) all to motor internal, and relative to adopting the circulating type of cooling at present, cooling effect significantly promotes; Be provided with this front and back ends sealing ring accordingly at the front and back ends of motor simultaneously, prevent insulation cold oil 7 from oozing out; Owing to not containing air in insulation cold oil 7, also stop the problems such as motor internal assembly gets rusty, extended the useful life of motor; In addition, due to sound insulate propagate in cold oil 7 time, its Oscillation Amplitude can be suppressed, and therefore, insulation cold oil 7 also serves the effect reducing motor noise; In addition, owing to having filled insulation cold oil 7 in casing, the change of magnetic flux can be caused, and the size of magnetic flux is decided by the size of gaps between rotor 5 and stator 4, therefore, consider and the utility model relates to a kind of synchronous machine, and experimentally gained, the size of air gap is set in 1.4 ~ 2.3mm, to ensure the efficient object of machine operation.
